What I'm looking for

I’m looking for a team where I can build production React/Next.js apps, drive strong performance (Core Web Vitals), and accelerate delivery using reusable components and thoughtful AI-assisted development—while maintaining quality with testing and clean API integration.

I’m a Senior Frontend Developer fluent in English, with 5+ years building production apps using React, Next.js, and TypeScript. I focus on measurable outcomes—like an 83% performance improvement and 50% reduction in development time—through reusable component systems.

In my most recent role, I built web applications with Next.js and React using TypeScript and Redux, crafting clean, reusable interfaces with StyledComponents and Material UI. I also used agentic AI development tools—Cursor, GitHub Copilot, and Claude Code—to boost productivity on repetitive tasks, while integrating data via GraphQL with Apollo Client.

I’m equally serious about quality and performance: I test with Playwright, React Testing Library, and Jest; manage versioning with Git; and ensure delivery readiness with CI/CD. I’ve also migrated dashboards from Power BI to custom D3.js, cutting load time by 75%, and implemented server-side rendering to improve performance and SEO in dynamic applications.
