How Code Reviews Made Me a Happier Developer
Something I've always wondered about I have always asked myself why, even with well-defined code guidelines, architectures, and design patterns, most of the time when I see a new application the code seems like it started from a good point and is getting messier and messier. I know devs are usually running against time, dealing with short deadlines and scope changes, and these are good excuses…
Writing clean, maintainable code is a challenge faced by developers, even when guidelines are well-established. Despite time constraints and evolving requirements, codebases often deteriorate into tangled, difficult-to-understand systems. Good code reviews prove invaluable in combating this code rot, making developers' lives easier and the codebase more robust.
When conducting a code review, I adopt the perspective of both the client and my future self. This mindset shifts the review from a simple approval task to a mission-driven effort. I assess whether the code supports the desired production feature, aligns with quality standards, and considers how I can assist my teammates through the review. My primary objectives during a review are to help colleagues, simplify my own future work, and ensure the codebase remains healthy and sustainable.
My motivations for code reviews stem from two core principles: first, I enjoy mentoring and teaching, using code reviews as a platform for career development and spreading knowledge of complex software architecture topics. For instance, when I encountered a microservice that had started with a strong hexagonal architecture and domain-driven design, I noticed some team members lacked the expertise to maintain the established standards.
Through constructive feedback, sharing resources, and discussions, I helped my team elevate their skills and maintain code quality.
Secondly, I dislike working under pressure or late at night. By thoroughly reviewing code, I prevent emergency tickets and ensure the application remains stable. I also gain confidence that the codebase is understandable and maintainable, which is crucial when modifications are required months down the line. Additionally, adhering to the appropriate architecture or design pattern for each situation simplifies future changes and extensions.
While I acknowledge the importance of automated checks like linting and code coverage, I believe code reviews should focus on higher-level aspects such as architectural coherence, quality standards, and team growth. In essence, a well-executed code review takes around 30 minutes to an hour of focused attention, yielding significant benefits: a codebase I'm comfortable with six months later, colleagues who are increasingly competent, and reduced stress for everyone involved.
The resulting positive impact extends beyond my team, contributing to a healthier company environment. Ultimately, code reviews are an investment that pays dividends in both my professional satisfaction and the success of the entire organization.
