Independent product studio · Solo, end to end

I build small products that go all the way out.

Five things I designed, wrote, shipped and now run in production — an EU marketplace, messaging rails for AI agents, uptime monitoring, an LLM visibility tracker, and a pixel-art mobile game.

Each one is a real product with real users, a real bill to pay and a deploy pipeline I own. Below: the actual interfaces, framed the same way.

The
studio

One person, the whole stack. Design in the browser, ship on Friday, watch the graphs on Saturday.

Every project here started as a problem I actually had. Buy European came from how hard it is to tell where a product is really made. FastSend from wanting an agent to text me when a build breaks. AlertsDown from uptime monitoring that costs nothing and explains itself. Klairia from nobody knowing how their brand reads inside an LLM answer. ViroPop because after four SaaS products I wanted to make something that was purely fun.

I run them all on one Docker Swarm behind Traefik, with the same deploy workflow and the same guarded production access. Small surface, few moving parts, no team to coordinate.
