COD3RS

Passionate developers working together. A community of developers, designers and tech enthusiasts with hubs in Esbjerg, Denmark and Košice, Slovakia.

Open-source collaboration, knowledge sharing without gatekeeping, and support for developers at every level. We also run Hack Esbjerg — a 24-hour hackathon hosted with EASV that brings together over a hundred students and developers.

Y-A-S - software team building full-stack applications

Y-A-S

We build software. Yet Another Solution is a small team crafting full-stack applications — from backend APIs to polished web interfaces.

Small team, real ownership: no hand-offs between account managers and engineers. We pick boring, reliable technology and move in short loops — discovery, build, review, ship.
