An accounting platform for French freelancers and auto-entrepreneurs.

I worked on it for almost four years, across most of the stack: product features, APIs, payments, banking integrations, electronic invoicing, infrastructure and deployments.

A big part of the job was also modernizing an older codebase while keeping a production SaaS running for real users.

Internal engineering agents built to handle recurring development work.

They can pick up tasks, work inside an existing repository, make changes and open or advance pull requests while the surrounding software keeps control of the workflow.

I worked on improving the system and making the agents more useful and reliable in day-to-day engineering work.

I built VULX because API security checks are much more useful when they happen while you’re building, not after something reaches production.

It scans OpenAPI and Swagger specifications against the OWASP API Security Top 10 and turns what it finds into concrete remediation steps that can be used in CI.

My own music streaming app.

You search for a song, press play, and Cocofy handles the rest from my server.

I built it mostly because I wanted to understand the whole path myself: search, downloading, storage, streaming and the infrastructure behind it.

Basically: my own little Spotify.
