Kevin — Senior Fullstack Developer
I design, I frame, I deliver, with one obsession: that the product truly works for those who use it.
Before coding, I spent 11 years creating content on YouTube and Twitch: 55,000 subscribers, 20 million views. There I learned to capture attention, simplify the complex, and think about the user before thinking about the technical aspects. I apply these reflexes to every project: that's what allows me to understand the 'why' before the 'how'.
For 6 years, I have been building fullstack applications in demanding environments: high-traffic e-commerce, SaaS, business platforms. I bridge the gap between product and technology: I talk to POs, I challenge specs, and I deliver clear, tested, maintainable code.
My stack
- REST, Node, Fastify, NestJS, PostgreSQL, ORM
- Front: React, Next.js, React Query, Tailwind, Material UI
- Redis, RabbitMQ, Websocket, OCR, Algolia
- Tests: a real requirement — unit, integration, end-to-end
AI in my workflow I integrate AI into the core of my development: Claude Code daily, skills and MCP servers (Playwright, Postgres...) to tool and validate work. Concrete result: I frame faster, I test better, and I deliver solid code.
Feel free to send me a message and present your product!
