What we do
We build websites, web applications, and backend systems that are lightweight, secure, and easy to maintain. We also support specialized crypto cases with a strict proof-of-ownership process.
How we work
We start with goals and constraints, then propose the simplest stack that achieves them. That usually means avoiding bloat and keeping dependencies under control.
Where we operate
We’re based in Prague, Czech Republic, and work with clients across Europe and beyond.
