About Omar

Embedded systems engineer, trained in demanding industrial environments

After several years developing and validating critical embedded systems, I design agentic AI systems, full-stack applications with integrated AI, all built with the same rigor: measured, tested, production-ready.

What I do today
→ Agentic systems & RAG: agents and document search engines with citations, which perform real tasks rather than just answering
→ Full-stack development: backend APIs (Python/FastAPI) and interfaces (Next.js/TypeScript), end-to-end
→ Software development with integrated AI: applications where the language model is a product component
→ Business automation connected to your existing tools

What I bring from my embedded and industrial background
→ Test and validation rigor applied to AI systems: accuracy, cost, and latency measured before any production deployment
→ Field experience in demanding industrial sites
→ Familiarity with strict specifications and technical documentation

Let's start with a feasibility audit of your processes before any development
