What I'm looking for

I seek senior engineering roles where I can lead full‑stack projects, mentor teams, and build secure, scalable web and mobile products in an agile environment.

I am a senior full‑stack engineer with over 11 years of experience building scalable web and mobile applications, with more than half my career spent working remotely.

I have led development of HIPAA‑compliant healthcare platforms, designed micro front‑end architectures, and built performant backend APIs using Node.js, TypeScript and GraphQL.

My work delivers measurable impact — improving UI/UX to increase users by 20%, reducing bundle sizes by 40%, and raising test coverage to 60% while mentoring peers and participating in code reviews.

I thrive in agile teams, collaborate closely with PMs, designers and QA, and focus on pixel‑perfect implementations using modern stacks (React, Next.js, React Native, Angular, AWS, Docker, Kubernetes).
