Adeel I.

Senior React and Next.js engineer with 12+ years of experience, working with clients on Upwork since 2013. I help startups and product teams ship fast React apps, and I fix the ones that got slow, messy or hard to change after a quick launch. Recent work outside Upwork: • Top-3 global pharmaceutical company in Basel: led frontend architecture for data-heavy analytics apps. Cut the bundle from 19.5 MB to 4 MB and dev server start from 10s to 400ms. • Baker McKenzie: enterprise React and TypeScript apps for an international law firm. • Glassnode: crypto analytics platform. Material UI contributor #59 with 29 merged PRs. What I do: • New builds and MVPs in Next.js, React and TypeScript, with Node.js or NestJS backends and PostgreSQL • Performance work: bundle size, Core Web Vitals, slow renders, build times • Cleaning up fast-shipped or AI-assisted codebases so new features stop breaking old ones • Design systems and component libraries (Material UI, shadcn/ui, Storybook) • AI features in production, including RAG and LLM integrations How I work: remote, clear async updates, overlap with US and European hours. I take on a small number of clients at a time so each one gets senior attention. Send me a message with what you're building and where it's stuck, and I'll tell you honestly whether I'm the right fit.
