Poland

Message

At pakke.dk, I own the backend of a Danish parcel shipping platform, including carrier integrations, pricing, and routing. I also built Refundify from zero, with a Django and PostgreSQL backend, a Next.js frontend, and carrier refund recovery.

I built a Rust/Axum parcel-shop finder with a two-tier cache, and shipped an ASP.NET Core integration with the Uniconta OData API. I work with coding agents daily and review their code carefully, especially where plausible answers can fail at the edges.
