I lead scalable React and TypeScript frontend platforms and testing strategy.
UkraineWhat I'm looking for
I lead the frontend of Healthbridge’s admin platform at Bluepes, guiding a team of three engineers through architecture decisions, code reviews, and technical direction in React and TypeScript.
I introduced a Playwright end-to-end testing flow with page objects, SSE mocking, and accessibility checks, then expanded unit and component coverage with Jest and React Testing Library. I build real-time, maintainable features with React Query, Server-Sent Events, and feature flags.
Previously, I built and maintained a shared React component library at ProArch for around five products, and developed financial-analysis interfaces and Highcharts visualizations for consultants. During engagements with Twilio and Trane, I delivered full-cycle web features, APIs, onboarding and pricing experiences, and equipment-data visualizations.
I focus on performance, security, and maintainability: profiling re-renders, stabilizing references, remediating Snyk findings, and keeping build tooling current. I’m open to remote lead and senior frontend roles.
