Senior🎓
Top SchoolLionel Tatkeu is a Senior AI Engineer based in Toronto with 8+ years building production-grade AI systems, from agentic RAG infrastructures and LLM pipelines to full-stack applications. He architects enterprise AI solutions that combine LLMs, vector databases, and orchestration layers, and has delivered 20+ projects across the UK, France, Mexico, Canada, and Africa while working closely with stakeholders to drive adoption. Technically fluent across Python, FastAPI, Node.js, TypeScript, React/Next.js, LangChain, LangGraph, and LLM fine-tuning, he’s driven measurable impact such as an 83% latency reduction in pipelines and 60% faster procurement cycles. Lionel founded AgentBridge, an open-source framework to make legacy systems AI-ready without rewrites, and co-founded Kawlo, an edtech platform that scaled to 200K+ users. He combines product ownership and hands-on engineering—having led data platform architecture and major refactors—to translate business needs into scalable, maintainable AI products. Constantly curious, he bridges academic training in data science with pragmatic deployment experience to help organizations move from prototypes to mission-critical AI.
