Freelancer profile translated to English.

Description

Fullstack developer for over 12 years, I support startups, SMEs, and software publishers from idea to production.

My main stack today: end-to-end TypeScript — Next.js 15 / React on the front-end, Node.js (AdonisJS, NestJS) on the back-end, PostgreSQL and Redis for data, all in a monorepo (Turborepo, Bun) with GitHub Actions CI/CD. I also develop mobile applications in Flutter (iOS + Android), and I work with Rust or Go on performance-critical components.

For the past two years, a significant part of my work has focused on integrating AI into products: LLM agents, MCP servers, RAG, multi-model gateways, and business workflow automation.

The main areas I work in are:

- Rapid prototyping and MVPs: transforming an idea into a live product

- Industrialization: taking an MVP and making it scalable, tested, and monitored

- SaaS, back-offices, and client portals

- Flutter mobile applications (iOS + Android)

- API design and monorepo architectures

- AI integration: agents, RAG, LLMs, workflow automation

- Refactoring and performance audits

I also work on:

- Connecting to external services (Stripe, GoCardless, MangoPay, Brevo, Firebase)

- Setting up production environments (Docker, GitHub Actions, Heroku, AWS, VPS, Cloudflare)

- Unit, functional, and integration testing

- Blockchain development: Solidity smart contracts, wallets, crypto payment gateways

Feel free to contact me: I ensure your project is clear to all parties and break it down into deliverables to give you visibility on timelines and budget.

See you soon,

Kevin
