I will build a fast modern web app in react and nextjs

FAST, TYPED, TESTED. NOT A TEMPLATE.

I've spent 6+ years building production React - three of them as Senior Frontend Developer at a German enterprise software company, where I took a codebase from 0% to 90% test coverage.

WHAT YOU GET

• React 19 + Next.js + TypeScript throughout, no any, no guesswork
• - Server-side rendering and real Core Web Vitals, not a Lighthouse screenshot
• - Responsive down to 320px, accessible by default (WCAG)
• - Multi-language and role-based access if you need it
• - Real tests: Vitest, React Testing Library, Playwright
• - Clean commits, CI pipeline, handover docs your team can read

ALSO GOOD AT

Rescue work. If you inherited something slow, untyped or untested, I stabilise it before adding anything new.

PROOF

My portfolio at iamsaeed.dev is twelve 3D WebGL scenes in a single React canvas with hand-written GLSL, and it still ships an accessible server-rendered fallback. I take both halves of that seriously.

Message me with your scope and I'll give you an honest estimate.
