Performance Developers

Hire Performance Developers

It is imperative that all types of software, such as web, mobile, desktop and cloud applications, maintain high levels of performance. Any amount of lag or slowdown experienced by users during tasks can lead to dissatisfaction, and if not addressed quickly and thoroughly, can have a detrimental effect on the company’s reputation.

It is essential to prioritise performance when designing next-generation online applications, mobile applications, desktop software products, and backend systems. All stages, components, and application modules must be designed to operate at an optimal level in order to ensure the success of the system.

It is critical to recruit performance developers with the necessary knowledge and expertise to identify and remove performance roadblocks, in order to ensure the highest levels of performance. These performance developers must possess the skill to ensure that all components of your application work quickly and efficiently.

The question is why there is a lag in performance.

Software performance is a critical part of the software development life cycle. Research has demonstrated that many performance issues are caused by inadequate coding techniques, such as the utilisation of an extra loop or an inefficient algorithm. Poor coding practices can lead to performance bottlenecks, which can negatively impact the user experience and potentially reduce the software’s value. Therefore, it is important for software developers to be aware of the impact their coding practices may have on the performance of their software.

Not because application developers are careless or unable to provide high-performance software.

When constructing an application, experienced software developers will make informed estimates regarding the necessary modules, data structures, and algorithms. However, these estimations have the potential to lead to a decrease in the overall quality of the program they have developed.

At times, it is not the code itself that hinders the performance, but rather how the code responds to a given condition, event, or data set. This can make it difficult for Quality Assurance Engineers and Testers to identify such flaws.

It is possible that there are other elements that could be hindering performance. As external Application Programming Interfaces (APIs) and libraries only offer an interface to the product, there is no way to gain an understanding of the intricacies of how the product functions.

For what purpose do you need Performance Developers?

It is evident that there are multiple possibilities that could contribute to a decreased level of application performance. Consequently, it is essential to bring on board performance developers who possess the necessary qualifications and expertise to consistently identify and address any issues with the software’s performance.

For instance, let us consider an airline booking service that offers passengers the capability to complete a variety of tasks, from purchasing tickets to digitally checking in and selecting their seats, adding baggage, selecting meals, using frequent flyer points, and much more. If we take into account the sheer magnitude of the development effort that is needed to make this system available through different media, it is easy to understand the complexity of the project.

  • Major desktop browsers on all of the most popular platforms.
  • Every mobile device’s browser.
  • Apps for both the Android and iOS platforms.
  • Internet service for data aggregation systems.
  • The registrar’s desktop computer.
  • In charge of the airport’s self-service check-in stations.
  • Apps designed specifically for use by the flight crew and ground employees.

All of this software must also be compatible with the airline’s existing back-end systems.

In order to build such an ecosystem, a big group of application developers with expertise in each technology would be needed.

Due to the intense level of competition, there is no room for delays, not even for a single day. Allowing for the possibility of weeks of delays is simply not an option. Therefore, it is essential that the software is created correctly the first time, without the need to remake it, since this would take up valuable time which could be spent on other aspects of the project.

Helpful Resources and Technology for Performance-Based Software Designers

Many resources exist to aid developers in their quest to create faster and more efficient software.

  1. Stress, load, and performance evaluations

    Application performance testing is an umbrella term that encompasses a range of tests, including performance testing, load testing, and stress testing. Through these tests, the functionality of a program is evaluated in multiple conditions or levels of usage or demand. To measure the performance of an application with various numbers of users, many metrics can be used, such as CPU utilisation, CPU activity, memory usage, page faults, instruction execution time, and Garbage collector utilisation.
  2. Assessment Tools for Performance

    When profiling is conducted at a more detailed level, it is possible to gain insight into the performance of a single logical process, such as saving a record, making an online payment, or querying a customer file. Instead of evaluating the entire transaction, only a small portion is analysed using conventional performance metrics such as CPU and memory utilisation. Further exploration is conducted on items like query execution plans, class instances, method call times, function call stacks, etc.
  3. Caching Resources

    Content Delivery Networks (CDNs) are an effective tool for performance developers, as they can be used to cache static and frequently visited items closer to the user, thus reducing the load on the system. Additionally, edge computing is a strategy that can be employed to improve user experience, as it allows for the storage of data specific to a certain geographic region on servers that are located in close proximity to the users.
  4. Communicating Without Being Together

    Upon being informed that the findings will be sent to them in due course, the user may conclude the session. This enhances both the efficacy and the level of service delivered to the end user. To achieve this, the work may be broken down into smaller, more controllable portions and tackled sequentially.
  5. Maintenance

    In order to ensure that your application is performing at its best, it is important to implement a routine maintenance plan that includes emptying the server cache, removing database logs, and recovering unreferenced memory. Additionally, your system architecture should be designed to facilitate automated upkeep. This will help to minimise the time and resources spent on manual maintenance tasks.

Functions and Obligations of Performance Builders

A Performance Developer is a software professional who works in close collaboration with all members of the software development team, including business analysts, programmers, quality assurance specialists, system administrators, database administrators, and network administrators. They have the technical skills and expertise necessary to develop a variety of web applications, mobile applications, online services, and distributed desktop applications for a broad range of industries and domains.

Their primary duty is to detect and eliminate any obstacles that may slow down the program under load.

  • From the very beginning of the development process, they use performance engineering and agile development practices.
  • They need to include code for reviewing performance within the application’s source code to provide real-time monitoring and diagnostics.
  • The team is cognizant of the fact that performance issues are often the result of components that are interdependent. Therefore, they are actively searching for solutions that will allow them to separate components, with the aim of enhancing the performance of the overall system.
  • Engineers specialising in system performance often look for strategies to switch from synchronous to asynchronous channels of communication.
  • Developers that specialise in performance use sophisticated profilers to examine every detail of the code.
  • During integration, they put the merged codebase through both traditional load testing and extensive performance testing.
  • Algorithm and data structure optimisation is a top priority across all of the program components.
  • They collaborate with those who build databases to enhance performance for the most common queries.

Fortunately, many of the issues that hamper the performance of an app can be addressed with the assistance of performance engineers. Engaging performance developers with the appropriate qualifications, educational background, and expertise enables you to avert these types of problems from the outset, allowing you to concentrate on creating a truly first-rate product.
