About Me
AI Engineer & Full-Stack Developer.
I'm Obi Ebuka, an AI Engineer and Full-Stack Developer with 4+ years building production-grade systems. I specialise in deploying agentic AI systems and RAG pipelines that help companies automate workflows and scale intelligently.
I've built and shipped AI-powered platforms across healthcare, energy, advertising, and e-commerce — integrating OpenAI API, LangChain agents, and intelligent automation into real products serving thousands of users.
My engineering philosophy: AI should do the heavy lifting. I build systems where agents handle repetitive operations autonomously — so businesses reduce costs, move faster, and scale without hiring.
