Full Stack Software Engineer with 5+ years of experience delivering production-grade web applications across Angular, React, Vue.js, Next.js, Python-Django, and NestJS ecosystems.

I specialize in building end-to-end systems — from architecting efficient REST APIs and optimizing PostgreSQL databases, to crafting seamless, performant frontends. I bring a strong QA mindset to everything I build: I've automated E2E testing pipelines, resolved 200+ critical bugs in production, and consistently improved system stability across teams.

Beyond engineering, I bridge the gap between technical execution and business outcomes — whether that's collaborating with cross-functional teams, leading hiring processes, or digitizing national sports infrastructure.
