Entry-level Full-Stack Developer specializing in web and mobile apps

Santa Cruz, CA1y exp

“Full-stack developer who has built multiple end-to-end products including a flight search platform, an AI-powered personal finance app, and a React Native workout app. Particularly interesting for teams needing someone who can combine modern React/Next.js frontend work with backend APIs, AI integrations, and pragmatic performance optimization in production-style projects.”

“Frontend engineer with experience building backend-driven UI systems (JSON-schema-based rendering) to enable rapid business-driven screen changes, including collaboration across design/backend/product/QA at Ozon Seller Center. Also created an internal npm package that generates TypeScript API clients from OpenAPI docs—initially for one project, later rolled out company-wide with CI testing and version pinning support.”

“Frontend engineer who has owned delivery as the only FE developer on a client project (Eltel), stepping into UX/UI and occasionally supporting backend while modernizing a React codebase incrementally. Known for replacing heavy legacy third-party UI libraries with simpler custom React components to improve performance and maintainability, and for working effectively in Scrum teams with strong QA practices (e.g., high unit test coverage and Playwright E2E where possible).”
