The studio
A studio built to kill agency waste.
fullstack.house is an AI-native software studio. We ship whole products — frontend, backend, infrastructure, AI — owned by seniors, not handed across a five-person team.
Why we exist
The founder left classic agencies precisely to kill the "five people, a month, budget evaporates" pattern. Most products in our portfolio were a one-person job — done well, done fast — once you remove the coordination tax and the handoff chain. So we removed them.
How we're different
AI is the first interlocutor for every task, not a buzzword. One senior owns each build end to end — research, delivery, testing, and closing the loop with you. We start from proven open source and tailor the last 20%. And every feature ships with automated tests and demo data, so quality is built in, not bolted on.
The founder
fullstack.house was founded by Jacek Tomaszewski — 20+ years shipping full-stack products end to end across TypeScript, infrastructure, commerce and AI. The studio is the headline; the founder is the credibility behind it.
Beyond delivery, that means the senior judgment a CTO brings: setting the architecture, making the build-vs-buy and stack calls, running technical due diligence, and getting a team and its standards off the ground. The public track record is concrete — a decade of conference talks and merged pull requests to the open source we build on, from Next.js to MikroORM.
