ABAdrien Bonvallet

About

One independent business, one point of contact, and tools that run in production.

I'm Adrien Bonvallet, an independent developer and EPITECH graduate. I build AI-based automation tools for companies handling too many documents by hand: reading emails, extracting from PDFs, and turning raw data into something teams and clients can act on.

I spent a year at California State University Long Beach, then worked in full-stack and mobile development at Sopra Steria Real Estate Software, maintaining applications used daily by social housing operators. That is where I saw that the real cost of software sits in the processes around it, not in the code itself.

I run a one-person business, which means something simple for you: the person scoping the project is the same one writing the code and answering six months from now. No sales layer, no chain of subcontractors.

How I work

Saying no when needed

If automation isn't worth it at your volume, I say so during the diagnostic instead of selling a build.

Shipping to production

A demo proves nothing. What counts is the tool running on Monday morning when nobody is watching.

No black box

You see what the tool extracted, with what confidence, and you can correct it. Every step is traceable.

Making you independent

Documentation, handover and readable code. The goal is that you could replace me, not that you can't.
