HI, I'M BADR
I build web and mobile products end to end: the interface, the services behind it, and the cloud it runs on. I also build the agent workflows my teams review, test, and ship with.
About / bio
I'm a senior full-stack engineer with 10+ years building fast, accessible web and mobile apps. I work across the whole stack: React and Vue on the front end, Python and Node behind them, and the cloud they run on. I care about strong TypeScript, thoughtful testing, and a user-centered mindset. I like working with product teams to deliver measurable outcomes, and mentoring other engineers along the way.
Tools & stack
AI / how I build
I don't just use AI tools. I build the workflow around them, so custom agents and skills handle the routine passes: drafting specs, reviewing pull requests, running smoke tests. The judgement calls stay with me. Every agent is scoped to the conventions the codebase already documents, so what comes back is something I can actually review.
Case studies
Three products I designed and built, from the first sketch to the app stores. Each one has its own story: why it exists, how I built it and what it changed.
01 / Selected work
French hospitals need doctors at short notice, and filling each shift meant emails, phone calls and paperwork. I designed and built Medzair to take that work off everyone's plate, from the hospital's request to the signed contract.
02 / Selected work
Polypro is an online language school where adults practise speaking with an AI tutor, on the web, iPhone, iPad and Android, with portals for companies and a back-office for the team. I led the mobile app and in-app billing.
03 / Selected work
Property managers handle repairs by phone, email and spreadsheets, and nobody knows where a job stands. I built Locafix end to end, from the website to the mobile app: one shared timeline for managers, tradespeople, tenants and owners, from the first report to the signed-off job.
Approach
Great software isn't just about shipping features. It's about building systems that are maintainable, secure, and pleasant to work in. I focus on long-term quality, so teams can move fast without bracing for what breaks next.
