What I'm looking for

I’m looking for a team where engineering quality, system design, and product impact are equally valued—helping ship reliable, high-quality systems with strong performance, maintainability, and accessibility.

I’m a Senior Frontend Developer with 10+ years of experience building complex, data-intensive web applications—from real-time analytics dashboards and microfrontend ecosystems to enterprise SaaS and collaboration platforms.

I architect scalable React/TypeScript systems and design real-time communication layers using WebSockets and SSE, integrating backend-driven workflows through REST, GraphQL, and modern API layers.

I build UI as infrastructure: reusable component libraries, Storybook-driven design systems with token-based theming, and consistent experiences across multiple teams and products. I also own features end-to-end, covering system design, API integration, CI/CD pipelines, and production monitoring.

I’m focused on performance, maintainability, and accessibility—continuously improving metrics, reducing bundle size, and delivering scalable frontend architecture through tight collaboration with product and backend teams.
