Ovo Okpubuluku, Senior AI Engineer and Technical Lead

Typing intro

Portfolio LinkedIn Credly Accredible Profile views


👋 Hi, I'm Ovo

What I build: enterprise data, retrieval, agentic workflows, ML inference, production

I'm a Senior AI Engineer and Technical Lead at Tactable, where I own end-to-end delivery of production AI systems for tier-1 Canadian banking and AdTech clients across Microsoft Azure, GCP and AWS. I take RAG agents, agentic workflows, ML inference pipelines and full-stack AI apps from solution architecture through security review, compliance and deployment.

Before tech, I spent over a decade leading teams under real consequence: running bank branch operations in Nigeria with a zero-fraud record, then leading safety-critical field crews in Alberta's energy sector. That background still shapes how I deliver. I own the work end to end, I care about risk, and I bring people along.

Making the switch into Data Science and ultimately AI Engineering has been the best career decision I have made.
