What I'm looking for

I seek remote roles where I can build scalable web/mobile products, improve reliability and developer productivity, and work collaboratively on impactful features.

I am a full‑stack software engineer with experience building high‑scale web and mobile applications using React, Next.js, TypeScript, Node.js and Python. I have delivered measurable product impact — increasing user retention by 40%, reducing production bugs by 35%, and accelerating development speed by 25% — while prioritizing usability, API automation and best practices.

I thrive in remote and collaborative settings, creating reusable component libraries, performance improvements and automation that save time and reduce errors. My work spans frontend, backend and mobile (Flutter/React Native), and I enjoy solving problems that improve product reliability and developer productivity.
