Senior front-end developer building scalable React/TypeScript products with test-driven code quality.
PolandWhat I'm looking for
I’m a Senior Front-End Developer with 6+ years of experience delivering production-grade web applications using React, TypeScript, and Next.js. I’ve built scalable UI architectures from scratch, including headless SDK libraries, complex data-driven interfaces, and CI/CD-automated delivery pipelines, with a strong code-quality mindset (80%+ test coverage standards).
At Andersen Lab, I lead architecture decisions across state management, API integration patterns, and component library design, while maintaining 80%+ coverage using Jest, React Testing Library, Vitest, and visual regression testing (Storybook + Chromatic). I’m also deepening my agentic AI expertise through agentic AI development work with Claude Code, MCP integrations, and custom skill workflows, and I take pride in mentoring teammates and collaborating closely with Product and backend partners.
