Додаткова інформація

I've spent most of my career working across the full application stack, so I'm comfortable moving between frontend development, backend services, and databases depending on what a project needs. I enjoy building new features, but I'm equally comfortable working with existing codebases, understanding how different parts of a system fit together, and making improvements without introducing unnecessary complexity.
My experience includes modern JavaScript applications built with React, Next.js, Vue.js, and Node.js, as well as backend systems developed in C#, Python, PHP, and Java. I've also worked with older applications that needed maintenance or modernization, so I understand that choosing the right technical approach often matters more than introducing the newest framework.
I pay particular attention to API design, database performance, and code maintainability. When something isn't working as expected, I prefer to understand the underlying issue rather than just apply a temporary fix. Whether it's a slow SQL query, an unreliable integration, or a frontend feature that has become difficult to maintain, I try to find solutions that are practical and sustainable.
I'm comfortable working independently and taking ownership of features from start to finish, but I also enjoy collaborating with other developers, discussing technical approaches, and reviewing code. I believe good software engineering is about more than writing code that works. It's about building something that other developers can understand, maintain, and improve over time.
