About Alexandre

I offer complete technical support, from design to production, on projects of all sizes: MVP, development from scratch, redesign, or scaling.

I work across the entire stack (front-end, back-end, infrastructure) with a pragmatic approach, adapted to your level of maturity, whether you have a specific need or just an idea to structure.

I pay particular attention to security, GDPR / CNIL compliance, and code quality. I also optimize performance and improve existing systems when necessary.

Each delivery includes clear documentation and tools to facilitate maintenance and evolution.

Objective: reliable, scalable solutions aligned with your business challenges.
