Over mij
I'm a Senior Software Engineer with 5+ years of experience building data-heavy web apps and e-commerce products with React, Next.js, TypeScript and Go. Today I build a multi-tenant e-commerce platform handling 300K+ products for a Swedish software company, working directly with clients from requirements to release.
On Fiverr I build admin dashboards, SaaS MVPs and AI chatbots, convert Figma designs to React, and fix apps made with Lovable, Bolt and Cursor. I use Claude Code daily, so you get senior-quality work, delivered fast.
