About the studio
A small studio with a high bar.
B&Br Technology is a founder-led software studio in Boston. Sean Cheick Baradji leads every project and works with a small team of engineers and designers when the scope calls for it.

Sean started B&Br after years of building software where getting it wrong has real consequences: a health-tech platform that scores 180,000+ supplements and flags risky combinations, operations software for a short-term rental business, and a GPS-verified app for field crews.
Those projects taught us what most agencies learn the hard way. The best automation is the one your team forgets is there. The worst is a new tool someone has to babysit. We scope for the first and design out the second.
Today we take on websites, apps, internal tools and AI automation for growing businesses, with a small team of engineers and designers around a founder who stays on every project.
Whatever we build, the standard is the same: does it work correctly, will it last, and does it solve the actual problem?
Projects we've delivered
The kind of work we take on.
- Operations automationTurnFlowBookings turn into cleaning jobs on their own, cleaners prove the work with photos, pay reconciles itself, and every calendar is checked daily for missing prices and restrictions before they block a booking. The owner just approves.Live in production
- Data & AI platformPharmaGuideA pipeline turns raw label data into a scored catalog behind an API. A retrieval (RAG) assistant answers with checked PubMed citations, and 41 reviewed safety rules respond before any AI model is allowed to guess.Website live · mobile app in TestFlight
- Field workforce platformFieldOps AIEvery clock-in, photo and overtime request is GPS-stamped and tracked, so crews are paid correctly, supervisors see the day live, and disputed invoices are settled with proof.Live in production

How we think
Four rules we don't bend.
Accuracy over hype
We recommend tools because they solve the problem, not because they're trending. If a $20/month tool fixes it, we'll tell you.
Scope in writing
Every project has a written scope, exclusions and test cases before work starts. Done means the tests pass, not that the deadline arrived.
Ship, then iterate
You see working software every week. Real feedback beats long specifications.
Built to hand over
Your accounts, your repositories, your documentation. You should be able to run what we build without us.
