React / Next.js Frontend DevelopmentAntzelo Balliu
Production-grade frontend development using React and Next.js, built by a senior engineer with ~9 years of experience shipping web products across B2B, B2C, and enterprise SaaS.
Whether you need a greenfield Next.js app, a legacy migration to React, or new features on an existing codebase, I bring the full picture: architecture, component systems, state management, API integration, performance tuning, and CI/CD.
What I work with daily:
TypeScript, React 18+, Next.js (App Router & Pages), Redux, TanStack Query, Apollo GraphQL, REST, Tailwind CSS, Vitest/Jest, GitHub Actions, Vercel.
Who this is for:
Product companies, startups, and teams that need a senior frontend engineer who can own a surface end-to-end, not just write components. I've done this at Rokoko (motion capture), Persado (enterprise AI SaaS), and Welcome Pickups (travel marketplace).
