I'm Younes Lesfer, a software engineer working across AI engineering, product development, and software architecture. I take ideas from a vague brief to a production system — scoping, proof of concept, backend, frontend, deployment, and the support that comes after. Most of my work sits where AI meets product: turning model capability into features that hold up in the real world.
I like problems where the hard part isn't the model — it's turning capability into something people can actually use, trust, and rely on in production. That's the work I care about, and it's the thread through everything below.
I build LLM-powered products, assistants, and workflow tools around concrete operational needs — designed to fit real workflows, respect permissions and constraints, and deliver value under practical limits, not just demo well.
I design backend foundations that stay understandable as products, teams, and requirements grow — clear module boundaries, sensible data models, and APIs that other people can build on.
I build frontend surfaces that wire cleanly into APIs, content systems, and real business workflows — fast, accessible, and honest about state.
I treat testing, CI, deployment, and maintainability as part of shipping, not cleanup afterwards — so what goes live keeps working.
