Summary
🤩
Rockstar🎓
Top SchoolNicolas Juelle is a Senior Software Engineer based in Montpellier with 11 years of hands-on experience building full-stack web and AI-driven products. He blends backend expertise in Node.js/NestJS and DynamoDB with modern front-end work in React and Vue, and has repeatedly introduced E2E testing, CI/CD and observability into teams. Recently focused on LLMs, prompt engineering, STT and production optimisation (OpenAI/Azure, Langfuse), he drives practical AI integrations rather than just experiments. As a former lead developer and tech lead, he pairs coding with specification writing, code review and team management to reduce regressions and accelerate delivery. He frequently ships side projects—browser extensions, RAG chatbots and LangChain-powered APIs—showing a knack for turning prototypes into deployable features. Comfortable across product, ops and R&D, he prefers pragmatic solutions that scale in production.
