🎒 Developer @ React • NestJS • Artificial intelligence 🤖 (OpenAI, LLMs, generative...)

I’m Jean-Vincent Quilichini, a product-driven engineer who enjoys turning complex systems - data, backend architecture, cloud infrastructure, and AI into production software that performs, scales, and stays understandable.

I build end-to-end products where Big Data meets applied AI: high-volume ingestion pipelines, search and analytics, LLM-powered enrichment, and clean user experiences on top. My work focuses on solving messy, real-world problems (latency, cost, observability, and maintainability) so teams can ship confidently and iterate without fear.

Strong engineering fundamentals : from React and Next.js frontends to NestJS, Fastify, and Express backends, I design systems with clear boundaries (DDD, CQRS when it makes sense) and APIs that stay boring in production.

Data at the core : PostgreSQL, MongoDB, Elasticsearch, Redis (structured, unstructured, search, real-time signals). I build pipelines, analytics, and relevance layers that turn raw data into decisions.

Applied AI, not hype : LLMs and generative AI are tools, not the product. I integrate them where they add leverage (automation, enrichment, summarization) while keeping evaluation, guardrails, and observability front and center.

Performance and UX matter : from shaving milliseconds on APIs to crafting fast, accessible interfaces with Tailwind, shadcn/ui, or Material UI, I aim to make complex systems feel simple. When needed, I’ll reach for WebAssembly or Three.js to push the browser further.

Production discipline : CI/CD, cloud infrastructure (AWS), Linux environments, monitoring, QA, and cost awareness are part of the job. I like releases that are uneventful.

I’m motivated by elegant solutions to hard problems and systems that are powerful and resilient.
Curious by default, pragmatic by choice, I build software that holds up long after the demo.

DM “MEET” or grab 10 minutes on my calendar and let’s put the machines to work so your people can do theirs.
