What I'm looking for

I seek backend/full‑stack roles where I can lead technical work, improve test automation, contribute to open source, and grow within collaborative agile teams.

I am a senior software engineer with five years of experience delivering full-stack systems, leading backend teams, and contributing to open-source projects. I have led backend efforts for e-commerce and microfinance applications and maintain tests for GNOME's OPENQA.

My technical work spans Node.js/Express, Spring Boot/Java, PostgreSQL, Firebase, Playwright, and test automation using JUnit and OPENQA. I’ve migrated test suites, implemented task scheduling with Celery, and built front-end experiences with React and Next.js.

I enjoy problem-solving in agile teams, writing reliable tests, and mentoring peers while continuously learning new technologies to produce maintainable, production-ready software.
