- AI integration into your product: LLMs (Gemini, GPT, Claude), data extraction from your documents, chatbots, process automation

- Secure REST API development (Node.js, Express, PostgreSQL, MongoDB)

- Website redesign, front-end migration, pixel-perfect Figma integration

- Automated testing (Vitest, Playwright, Cypress), CI/CD, production deployments

- SEO-optimized landing pages, accessibility, responsiveness

I work autonomously or integrated into your team: I define the needs with you, I code, I test, and I deliver to production.

As each project is different, I offer support with a daily rate adjusted to your needs: from €345 to €850 / day, depending on the scope, technical challenges, complexity, and expected level of involvement.
