Yuliya H.

I’m a Full-Stack Web Developer building web applications and extending existing systems — with a strong focus on backend logic, API integrations, and production reliability. What I help with: • Web apps & internal dashboards (roles, access control, structured user flows) • REST APIs, webhooks, data sync, secure data flows • Payment-connected workflows and third-party integrations (scoping → implementation → staged releases) • Performance & stability in production (Core Web Vitals, caching, bottlenecks) • Clean UI implementation from Figma with maintainable components How I work: I structure features as components/modules, keep changes predictable, and avoid “quick fixes” that break production later. I can join an existing codebase and improve it safely, or build new modules end-to-end.
