About this gig

Need a web app that works in production, not just a demo?


I build full stack apps with NextJS, React, TypeScript, Node and MongoDB. My main project is ByggExp, a live paid SaaS for construction firms: website, admin panel and mobile app on one backend.


What I can build:

  • MVPs and SaaS products
  • Customer portals and booking systems
  • Login, roles and user accounts
  • REST APIs and database design
  • Stripe payments and email
  • Fixes and new features in existing NextJS or React apps

How it works:

  1. Message me with your idea before ordering
  2. I reply with a written scope and a fixed price
  3. Progress updates during the project
  4. Delivery with source code in your GitHub and a deploy

You own 100% of the code. Clean TypeScript, responsive UI, GDPR-aware data handling.


Based in Stockholm (CET). English, Swedish or Russian.
