What I'm looking for

I seek remote roles where I can build performant React/TypeScript products, contribute across stack, work in small Agile teams, and deliver measurable business impact.

I am a React developer with 3+ years of experience in TypeScript, Node and REST API, having delivered 8+ commercial React+TypeScript applications and led three Agile projects for remote US/EU clients. I focus on performance optimization, measurable business outcomes, and reliable remote delivery with EST/CEST overlap.

My work spans frontend and backend responsibilities: building core features, integrating REST APIs, and improving load times (examples include a 35% loading-time improvement and a 45% surge in direct bookings for a client site). I also deliver cross-platform/mobile MVPs and internationalized products that increase user engagement and SEO performance.

I thrive in small remote teams, using tools like Jira, Slack and CI/CD to deliver on schedule; I teach programming part-time, emphasizing quality, documentation, and onboarding improvements that reduce design-debt and speed up new-hire productivity.
