About this gig

You're not hiring a developer you're getting a Senior Lead Frontend Engineer with 9+ years of hands-on experience building production-grade, scalable React applications used by real users at scale.

I specialize in:

  • React.js & Next.js (App Router, SSR, ISR, CSR)
  • TypeScript including full JS TS migrations
  • Scalable frontend architecture & design systems
  • UI performance optimization (Core Web Vitals, rendering strategies)
  • Tech leadership, code reviews & team mentoring

What I've delivered in production:

  • Reduced runtime errors by 30% through a full JavaScript TypeScript migration on a large codebase
  • Improved UI performance by 25% using advanced rendering techniques (memoization, lazy loading, virtualization)
  • Led high-performing frontend teams, driving velocity and code quality across sprints

Who this is for:

  • Startups needing a solid, scalable frontend from the ground up
  • Teams who need a senior engineer to fix performance bottlenecks or refactor messy code
  • Companies migrating from JavaScript to TypeScript
  • Projects that need Next.js architecture done right (SSR vs SSG vs ISR decisions)

What you'll get:

  • Clean, well-documented, production-ready code
  • Architecture that scales not just code that
