I design and ship production software on my own: Next.js, TypeScript, Supabase, Postgres, Vercel, and LLM agent workflows. Nine products built and running. Based in Osijek, Croatia — EU company, EU VAT, EUR invoicing, CET.
A B2B tyre-distribution portal with a technical-equivalence engine: when the requested article is unavailable it computes valid substitutes from the specification and ranks them without crossing a technical band. Multi-language, six supply states, full audit of every claim on screen.

How I work
Good fit
Next.js / React / Supabase / Postgres builds
Adding AI or LLM features to an existing product
Rapid MVP and prototype work
Document processing and data-extraction pipelines
Internal tools and dashboards
Well-scoped pieces with a clear definition of done
Not a fit
On-site work
Large legacy codebases in unfamiliar stacks
Native iOS / Android beyond React Native
Full-time team embedding
Terms
€450/day, remote, invoiced monthly in arrears in EUR, 30 days. VSN j.d.o.o. is a Croatian limited company with an EU VAT number, so invoicing inside the EU is straightforward.
I am happy to start with one small, self-contained piece so you can see the work before committing to anything further. Most agencies I speak to prefer that, and so do I.
