Rennes is an engineers' city: digital, telecoms, cybersecurity, with companies that know what good code is. We work with them remotely, from Aix-en-Provence, applying the same standards: TypeScript, tests, CI, documentation, and security taken seriously from the first commit, in English or French.

## What we do

### Secure applications and APIs

Proven authentication, secrets out of the code, monitored dependencies, audit logs, an audit before production: the rigour of the Rennes cyber cluster applied to your project.

### Business tools for agri-food

Traceability, production tracking, cooperative and supplier portals, ERP connection: applications for Breton manufacturers.

### Websites for local authorities and non-profits

RGAA accessibility, GDPR, publishing by non-technical teams, controlled budget: websites that last.

### Reinforcement for technical teams

A senior remote developer plugged into your Git, reviews and CI, for a defined period.
