Digital factory – custom software

Powehi's Digital Factory designs custom business software delivered in full ownership on a sovereign, reversible open source foundation. Unlike SaaS solutions that lock in your data and processes, our approach guarantees technological independence: source code delivered, hosting of your choice, zero vendor lock-in. We cover the full cycle: functional scoping, UX design, API-first development (FastAPI, NestJS), modern front-end (React, Vue), automated testing, CI/CD and production deployment. Our BPM-first method maps and optimises your processes before coding. Result: applications that fit your business, evolve with you and reduce iterations by 30-40%. Tech stack: React, TypeScript, FastAPI, PostgreSQL, Docker, Kubernetes, GitLab CI. Sovereign France/EU hosting with OVHcloud or Scaleway.
