About Mathis

Hello!

Passionate Fullstack Developer with 5 years of immersion in tech, I assist you in the design and development of your Web and Mobile solutions.

My background is hybrid: I have the rigor of large corporations (Bouygues Telecom, Ministry of the Interior) and the agility of startups (Rutafem, Wenly). I don't just write code, I make sure it meets your business objectives.

What I can do for you:


Application Creation"From Scratch": From idea to production (Web & Mobile).

**Modern Frontend Development**: Responsive and performant interfaces (React, Next.js).



**Backend & API Architecture**: Scalable and secure systems (Node.js, Express, PostgreSQL).



**DevOps & Deployment**: Setting up robust environments (Docker, Kubernetes, CI/CD).



**Technical & Product Consulting**: I challenge your ideas to optimize the MVP and time-to-market.

My Preferred Tech Stack:


**Front**: React.js / Next.js / React Native (Expo) / Tailwind CSS



**Back**: Node.js / Express / Firebase / Supabase / Prisma



**Infra**: Docker / Kubernetes / Vercel / OVH


Why work with me? Having co-founded my own projects, I understandyour budget, timeline, and quality constraints.I am proactive, transparent, and solution-oriented.
