What I build with Next.js

Next.js is the React framework I reach for when a site needs to be fast, SEO-friendly and interactive at once - marketing sites, headless storefronts, dashboards and full-stack apps. I build and refine Next.js projects end to end: frontend, API routes, rendering strategy and performance.

Many Next.js requests are refinement and rescue: improving Core Web Vitals, migrating from Pages to App Router, upgrading old versions, fixing hydration and SEO issues, and adding features to an existing codebase. I also build new sites and apps from scratch.

I work as an independent developer - you communicate directly with me, with clear estimates and full responsibility for the architecture and result.

Why Next.js and why me

Next.js combines the interactivity of React with server rendering and static generation - so you get a modern app feel without sacrificing SEO or speed. I build fast, maintainable frontends that rank and convert.

Fast by default

SSR, SSG and ISR deliver instant pages and top Core Web Vitals scores out of the box.

SEO-friendly

Server-rendered HTML, clean metadata and structured data help pages rank in Google.

Full-stack ready

API routes and server actions let one codebase handle frontend and backend logic.

Maintainable code

Typed, componentized React that your team can extend long after launch.

Work directly with a specialist

No middlemen: you communicate directly with me - from architecture to launch and support.

Long-term support

I maintain the project after launch: updates, fixes and new features as your product grows.
