What I'm looking for

I seek roles building scalable backend and full-stack systems using Node.js and modern JavaScript, in collaborative, agile teams that value code quality, mentorship, and measurable user impact.

I am a Senior Software Engineer with eight years of experience designing and building scalable digital products across consulting, media, and streaming platforms. I specialize in Node.js backends, JavaScript frameworks (React.js, Angular.js), and API development, and I consistently apply OOP and TDD to deliver clean, testable, and maintainable code.

At Spotify I developed and optimized large-scale audio streaming services, introduced microservices for improved scalability, and mentored junior engineers; previously I built full‑stack applications for consulting clients and gained foundational engineering experience early in my career, using Docker, Git, SQL/NoSQL databases, and Agile practices to deliver reliable production software.
