Back to original languageAbout Baptiste
🔧 I design and develop robust APIs and back-end services, mainly with Node.js and NestJS.
I work on projects from scratch as well as on existing codebases to evolve or stabilize them.
My experience has led me to work in various contexts: high-volume SaaS, real-time applications, technical partnership integrations.
💡 I pay particular attention to code quality, maintainability, and architectural clarity — because a well-designed back-end means fewer bugs, less debt, and more long-term velocity.
