Hello, I’m Loïc Lepinois
AI Engineer & Senior Tech Lead building AI agents and RAG systems in production

I build AI agents and RAG systems that actually run in production, right now for two SaaS products. With 10+ years as a developer and tech lead, I also help small teams write better code and ship things that last.

Services

01
AI engineering & LLM products
Real AI features for production: RAG over your own data, agents that can take actions, and the plumbing to keep it reliable. I stay provider-agnostic with the Vercel AI SDK, so you're never locked into a single model.
02
Technical leadership & team enablement
Hands-on tech leadership for junior or growing teams. Code reviews, architecture decisions, best practices, and mentoring to help teams gain autonomy and confidence.
03
Product & SaaS development
Design and development of solid SaaS products, from early MVPs to growing platforms. I focus on clean architecture, maintainability, and long-term product quality.
04
Pragmatic UX & product decisions
UX work tightly connected to development. Flow improvements, usability fixes, and product decisions that make features simpler to use and easier to maintain.

About me

After studying computer science at EPHEC and UCL, I spent over ten years as a developer and tech lead in startups, with a few years teaching young developers in Vietnam and Madagascar. Today I'm an independent AI Engineer and Tech Lead in Brussels. I build AI features that actually get used, and I help engineering teams grow more autonomous along the way. I also recently finished a UX certificate at ULB. Available in Brussels and remotely.
And now, here’s just me, posing for you 🫰
