Distinctive Features of More Experienced Programmers

To what extent do intermediate, senior, and lead developers vary from one another?

If you are in the process of hiring a developer, you may be wondering about the differences between Junior, Midlevel, Senior, and Lead developers. These distinctions mainly come down to their level of experience and expertise, although they may be subtle. When looking for a new team member, it is important to bear in mind that a Junior developer will require close monitoring and frequent code reviews, making it less suitable for creating the framework for a whole website. On the other hand, a Senior developer is not necessarily needed to help a team that is already in place to track issues and bottlenecks.

However, it is not unusual for companies to encounter difficulties when recruiting skilled programmers. Businesses are often seeking experienced and senior developers with extensive relevant knowledge. Nevertheless, the skill and experience levels may not always be of equal importance for all projects.

When recruiting, it is essential to identify applicants who possess the relevant skills and experience for your team and project, rather than simply focusing on the most experienced. Therefore, it is important to consider which developer level is best suited for the project: Junior, Midlevel, Senior, or Lead?

What’s the Difference Between a Front-End Developer and a Back-End Developer while Creating Software?

Let us examine the two main roles necessary for the building of a web application, prior to examining the distinctions between Junior, Midlevel, Senior and Lead developers.

Your project’s code can be written in a number of different languages. You need to ensure that you have a front-end and a back-end developer to ensure the success of your application. The front-end developer is primarily responsible for the visual design and user interaction on your website, whilst the back-end developer is responsible for tasks such as maintaining databases and writing programs. Working together, they are able to provide a vibrant and engaging online space. Both are essential for the success of your application.

Listed below are some key abilities required for any of these positions:

Abilities as Both a Front-End and Back-End Developer

When determining the appropriate level of expertise for a project, it is important to take into account the scope of the project and the associated responsibilities. For example, you may choose to employ a Junior role to manage databases and data collection. This individual can begin by taking on manageable tasks and learning from more experienced team members. With time, they can be trained in the way your business operates. For major changes to the user interface, it is advisable to bring in a Senior developer with a front-end specialism. Additionally, a web designer with a creative approach is also necessary.

Here are the knowledge areas included by each degree of competence, as well as the advantages of employing someone with certain backgrounds.

Apprentice Programmers

Essential Abilities for Entry-Level Web Designers and Programmers

Web Markup Languages

First and foremost, programmers need fluency in these three languages. Definitely not up for discussion!

The combination of HTML, CSS and JavaScript is essential for successful web development. Each of these technologies has unique properties and benefits, making them ideal for creating and managing websites.


The acronym “HTML” refers to the HyperText Markup Language. To put it simply, it’s a website’s framework.

HTML is a markup language, which uses tags to identify and determine the purpose of content on a web page, rather than using a programming language for operations.

This blog post is an example of how HTML tags can be used to create the featured image, title, subheadings and body paragraphs.


CSS, which stands for Cascading Style Sheets, is HTML’s cosmetic (seriously).

This language primarily focuses on the visual presentation of HTML elements in a web browser. HTML is used to create the structure of a website, while Cascading Style Sheets (CSS) is used to add the finishing touches, such as colour schemes and font sizes.

We would greatly appreciate it if you could take the time to revisit our online store. Our brand has taken great care in developing the colour scheme and fonts to ensure the best possible user experience. CSS is responsible for displaying all of the content on the page, otherwise, the content may not be visually appealing.


Before continuing with JavaScript, it is important to take a break. As a web designer, you are experienced in HTML and CSS and can create a website with a high level of aesthetics. Have you considered all of the elements required for the site?

In today’s digital world, the success of a website is determined not only by its visual appeal, but also by its ability to motivate people to take action. For example, if you are creating a website for your business, you want to attract visitors and expand your online visibility. You hope that those who stumble upon your website will choose to make a purchase. It is therefore essential to create functional interactions. This is one of the main reasons why JavaScript was developed.

JavaScript is a programming language that enables websites to create interactive elements, such as confirmation dialogues, call-to-action buttons and other dynamic components, based on the user’s actions.

Created Using Adaptive Mindsets

Responsive design is an approach to designing graphical user interfaces that enables information to be optimised for a variety of display sizes. Websites that are able to provide a seamless user experience across desktop, mobile and tablet devices have been designed with responsive design concepts in mind and implemented in their code accordingly.

Recent research has indicated that in 2023, 16.2% of all internet users will be mobile users, a significant increase from the current level. According to Statista, by 2023, 80% of the world’s population is expected to own a smartphone. Furthermore, the data also shows that 69.4% of users have shopping applications installed on their mobile devices, and 55.4% of shoppers are using their smartphone to make purchases.

A missed chance to attract new clients is what happens when your website lacks a responsive design.

Frameworks for JavaScript

It has been highlighted how important it is for young front-end engineers to have a good understanding of JavaScript. Despite its essential role in web development, JS can present some challenges. This is the reason why frameworks exist.

JavaScript frameworks provide developers with access to pre-built code libraries, allowing them to save time by avoiding the need to create solutions from scratch or from the ground up. This enables them to focus their efforts on higher value tasks.

It is not essential for a junior front-end engineer to be knowledgeable about the numerous JavaScript frameworks available; however, it is important that they can quickly become familiar with the frameworks which are necessary for the website development project.

Node.js, React.js, AngularJS, and Vue are some of the most well-known JavaScript frameworks.

Verifying and Fixing

As a front-end developer, even with little experience, it is important to devote time and energy to learning testing and debugging techniques. Although bugs are a natural part of the development process, they can cause major issues if they go undetected until late in the cycle. It is the responsibility of developers to aim to write and maintain bug-free code, which can be achieved through regular testing.

In web development, testing can encompass a range of approaches, from functional testing that focuses on a particular feature to unit testing that isolates an individual line of code that may be causing an issue.

By utilizing these procedures and collaborating with an experienced developer who is proficient in testing and debugging, you can be confident that your upcoming website or the one they are managing will be free from errors and will operate effectively.

Web Efficiency

Speed is an important factor to consider when assessing web performance. Optimising a website’s performance ensures that pages are displayed quickly and efficiently within the user’s web browser.

Web pages which take a long time to load are often not well received. Most people will not stay on a website, regardless of how attractive it is, if it takes too long to load. This is something which should be avoided when creating a website for your business. It is important to remember that your brand is made up of the products you offer and the story you tell about them.

Web pages that load quickly are highly appreciated by visitors and are more likely to result in return visits. Studies have found that if a website fails to capture a user’s attention in three seconds, 40% of visitors will abandon the page. Slow loading speeds can potentially lead to a loss of customers for even the most established businesses. For example, the BBC reportedly loses 10% of its visitors for every second that its website takes to load.

Front-end developers possess the expertise to optimize and accelerate website performance. It is essential to ensure that your developer has experience with back-end systems to gain such capabilities. It may be possible to speed up the website by reducing the size of the CSS and JavaScript files, or it may be contingent on the image format used. Professional front-end developers are able to tackle any issue that may be causing a slowdown in website performance.

Controlled Versions of Files

Software technologies known as version control systems are beneficial to programmers, as they enable tracking and implementation of changes to code over time. Each alteration to the code is recorded in the version control system’s database. If a mistake is made while developing a website, the original code, stored in the repository, can be used to rectify the issue, thereby eliminating the need for panic.

Your developer can trial new ideas for the website by simulating them in a Version Control System (VCS) before making any changes, thus avoiding potential issues.

Due to the ever-evolving nature of websites, Visual Studio Code (VSC) has become an essential resource for developers. This is because the complexity of these systems has created a range of challenges that must be addressed. Fortunately, VSC provides a degree of flexibility when it comes to mistakes, ensuring that developers can quickly get back on track.

Jobs for a New Programmer

It is important to remember that junior developers require regular oversight and code review. They have not had the same level of experience as more seasoned developers, so may be more prone to making errors or overlooking issues. Even if the junior developer is working on an existing process, senior or mid-level team members will need time to train and evaluate their work.

The primary responsibilities of junior developers include the following:

  • Help the manager of software development with programming and design tasks.
  • Join corporate planning sessions and provide input.
  • Improve your coding knowledge by updating and expanding your horizons.
  • Code and keep it updated.
  • Fix small issues and keep an eye on the technical health of internal systems.
  • Attend to the demands of the development staff.
  • Obtain feedback from users on the features of the software.
  • Fill out paperwork.
  • Prototype new features and test them out.

Some Pros of Bringing on a Young Coding Team

  • Companies should not overlook the potential of young people, who often have an untapped aptitude. By investing in training, businesses can tap into this talent pool and secure top talent that could otherwise be lost. Many young developers demonstrate a high level of intelligence and a quick learning capacity, making them an ideal candidate for mentorship programmes. It should be seen as an investment, which can benefit both the company and the developer.
  • Junior members of an IT team are renowned for their ingenuity and originality, bringing fresh perspectives to challenging issues. They are often at the forefront of the latest technology and ideas, providing innovative solutions to difficult problems.
  • Senior developers have a great deal of flexibility due to their relatively free schedule outside of work. Whilst they may have other commitments, they are often open to working longer hours if it provides them with the opportunity to progress professionally.
  • Junior staff tend to be highly motivated and keen to gain experience and knowledge. This enthusiasm often leads to increased productivity and employees performing to their highest potential.
  • Salary reductions: IT professionals can be costly, particularly in countries with high living costs. Hiring a junior professional rather than an experienced one could save thousands of dollars.

To What Extent Do Junior Developers Work With Senior Developers?

The level of experience of a developer is closely related to the amount of responsibility they are assigned in the workplace. Entry-level job seekers have theoretical knowledge of computer science but lack practical experience.

Junior developers are defined as those with less than two years’ professional experience. Whilst they may only have a basic understanding of software, they have experience with practical tasks. Both tiers of developers can offer valuable contributions to a project, however the decision of which to choose should be based on the team’s individual requirements. For example, if only occasional help is required with a few tasks, then hiring an entry-level developer might be beneficial as they can be taught alongside existing staff. Furthermore, a junior developer who has worked on a similar project before may be employed; they are likely to have a better mastery of tools and a more comprehensive understanding of a development project, however they should still be supervised and monitored.

Intermediate Programmers

Required Abilities for Intermediate Web Designers and Programmers

Inline Style Sheet (CSS) Preprocessors

To ensure a consistent appearance across different web browsers, it is essential to have a developer with intermediate CSS proficiency. Midlevels are responsible for using CSS Preprocessors to produce CSS from the preprocessor’s syntax. Additionally, they must also ensure that the website remains consistent in their spare time.

Translators for JavaScript

JavaScript is an essential tool for any developer and it is expected that a Mid-Level developer has some knowledge of Transpilers. Transpilers allow code to be converted from one language to another without altering the original source code and are widely used in software development, especially by front-end developers.

  • CoffeeScript is a similar programming language to Ruby that may be used with the Ruby on Rails framework.
  • Microsoft is pushing TypeScript, which is a precise syntactical superset of JavaScript.


NoSQL, an acronym for “Not just SQL”, is a database employed for storing, replicating and retrieving information. This technology was developed by industry leaders such as Facebook, Google and Amazon to assist in the organisation and management of large volumes of data. To facilitate scalability, it is important for mid-level engineers to have an understanding of the database management system. The organisation and maintenance of the database will determine the ease of use for clients when accessing the site. Developers are able to manage data as well as optimize the functionality of the website.

Here’s more on finding and hiring a MongoDB programmer:

APIs, Servers, and Databases

Mid-level back-end developers should possess an in-depth knowledge of modern server technologies such as Nginx, Apache, and IIS, as well as a thorough understanding of Linux for managing databases and optimizing server performance. Additional expertise with web services and APIs is essential, particularly with protocols like Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) in order to ensure the successful running of the programme.

Interface and User Experience Design

As a Front-End Developer at an intermediate level, it is essential to possess a thorough understanding of User Interface (UI) and User Experience Design (UX). This position requires providing innovative solutions to improve the interactivity of websites and their UI. Additionally, the role involves working with other colleagues to identify and address issues, as well as collaborating with other departments to enhance the user experience.

  • Perform a code audit and implementation of the project.
  • Adhere to technical specifications and modify scripts as needed for the project.
  • Find areas of improvement in ongoing initiatives, and implement them.
  • Put into action and conduct software testing
  • Creating software quality assurance processes.
  • Collaborate with designers, QA testers, and the rest of the software development team to analyze the demands of the end users.
  • Work along with and coordinate the many parts of the organization
  • Maintainability relies on meticulous documentation of each step in the development process.

The Value of Hiring Experienced Developers

  • Mid-level employees, with two to four years’ experience, have greater autonomy than junior-level personnel. Their proven capability in dealing with similar tasks and issues makes them ideal for ensuring the independence necessary to carry out assignments and resolve difficulties.
  • Between Junior and Senior staff, there is sufficient expertise to generate ideas, but not to formulate a strategy. Having someone on the team who is experienced in the subject matter but not yet able to lead is a great solution if the team is already established.
  • Teamwork is essential for mid-level employees. Although they may not have direct superiors, they must work closely with others in their team and across divisions. This requires a collaborative approach, with all team members operating within the company’s policies and making their own decisions.
