About this gig

Is your app slow, outdated, or hard to maintain? Lets turn it into a high-performance masterpiece.

Building a website is easy; building a scalable, high-converting, and lightning-fast experience is hard. Most developers leave you with "spaghetti code" that breaks. I specialise in taking existing Next.js projects and transforming them into premium digital products.


What I Offer:

  •  Refactoring: Converting messy code into clean, modular TypeScript architecture.
  •  Redesign: Modernising your UI/UX with cutting-edge aesthetics (Glassmorphism, 3D backgrounds, smooth scroll).
  •  Optimisation: Achieving 90+ scores on Google Lighthouse (LCP, FID, CLS).
  • ️ Bug Squashing: Fixing those persistent React hydration errors and logic flaws.
  •  Feature Expansion: Adding new pages, dashboards, or API integrations.

Why Me?

  • Expertise in Next.js 15, React, TypeScript, Tailwind CSS, etc.
  • Focus on User Experience: I don't just write code; I design for your users.
  • Clean Code: I follow industry best practices so your app is easy to scale later.
  • Direct Communication: You get regular updates and a collaborative partner.
  • Tech Stack I Use: Next.js (App Router), TypeScript, Framer Motion, Lenis Scroll, Three.js.
