My approach is to understand the business problem first and then build solutions that are easy to maintain and scale. I also have extensive experience reviewing code, mentoring developers, improving application performance, and resolving production issues. Whether it's optimizing database queries, reducing API response times, refactoring legacy code, or designing a new microservice, I focus on delivering solutions that work well in production.
