Backend developers are in charge of creating the structure and logic for all software projects. They construct the functionality behind our favorite programs and maintain and enhance it over time, so we can use them without too many errors and issues.
- Technical debt and over-engineering
Technical debt occurs when developers violate the SOLID and DRY principles by taking shortcuts, such as omitting testing or code review and refactoring. This might happen when a project falls behind schedule or goes over budget. In this case, developers take a calculated risk by releasing the MVP before it is ready.
Other times, developers get sidetracked or too focused and forget the KISS (keep it simple, stupid) principles. As a result, they overcomplicate inconsequential topics using needlessly sophisticated procedures. Essentially, instead of concentrating on aspects that influence overall performance or bottlenecks, they over-optimize elements that are not as important. As a consequence, critical functionalities operate poorly, and end-users have a negative experience.
How to Avoid It
Rebuilding a project entails twice the effort and twice the cost (best case scenario). So, communication is the first step in preventing excessive technical debt or over-engineering in your project. If you are a product owner or project manager, ensure that your team understands the requirements. More crucially, a clear and realistic list of deliverables, their priority, and dates. Chaotic criteria, such as “everything is critical and everything must be completed by tomorrow,” will be greeted with turmoil.
Instead, begin with a small MVP that highlights a few key features and expand from there. With each release, your engineers have an opportunity to consider the next set of essential features and choose which technologies and techniques to use.
- Inadequate or non-existent testing
Testing is a crucial aspect of the development process. It enables developers to detect and correct flaws and problems in real-time. While it is hard to test everything, it is critical that developers design and execute tests for as many situations as feasible throughout each stage. Improper testing or omitting tests entirely results in an unpredictable and unreliable backend. Aside from that, maintenance is hard since your developers will never know what is wrong and why.
How to Avoid It
Write and run tests both when developing new features and after addressing particular issues. Use the agile approach of TDD (test-driven development), where you create, test, and repair before moving on. In the long run, this will save the project a lot of time and money since you will uncover and repair issues before they damage anything else.
Another method is to have someone evaluate your code. A pair (or many) of fresh eyes is always encouraged, whether it be a CTO, your tech lead, or other members of your team.

- Not inspecting or evaluating static code
Peer-to-peer code reviews are often used in development firms. When a developer is ready to submit a feature, the code is sent to another developer for evaluation. This individual personally reviews each line, and if everything is in order, the code is pushed to the main branch.
Static code analysis, also known as source code analysis, is a more automated procedure that examines the code before it is delivered. Static code analysis tools are used by developers to examine code against development rules such as MISRA and report back.
How to Avoid It
First, trust your staff and be open to comments. Your team members each have their own set of talents that will boost the quality of your job. They also have diverse experiences that may provide you with insights you may not have considered.
At the same time, there are several tools available for automated static code analysis that may be useful. So, choose one that is right for you and your project and adopt it as soon as feasible.
- Technology and tool chaos
There are several programming languages, frameworks, libraries, and tools that developers utilize on a regular basis. As a result, each developer has their preferences and often disagrees with one another over which technology is ideal for a given circumstance.
How to Avoid It
Before beginning the project, ensure that you and your team agree on and keep to a set of tools that you will use throughout the development process. This is not the time to be innovative or adventurous. Using too many tools or a too complicated toolset will make the project harder to manage since the developer in charge will need to understand all of the technology utilized in the development process.
