About me
I'm a full-stack web developer specializing in React, Next.js, Node.js, and TypeScript. I build fast, scalable web applications and websites — from sleek landing pages to full SaaS products — with clean, maintainable code throughout.
I work across the entire stack: pixel-perfect frontends, solid REST APIs, third-party integrations, and deployment. I write TypeScript by default and care about code quality, not just getting things to "work."
What I can build for you:
- Landing pages and business websites (Next.js, TailwindCSS)
- SaaS applications and web app MVPs
- REST APIs and third-party service integrations
- Migrations from legacy stacks to modern technologies
I communicate clearly, hit my deadlines, and keep you updated throughout the project — no surprises. If you need someone who can take ownership of a project from start to finish, let's talk.
