Deo Shankar

Deo is a Cloud & AI Architect who lives at the intersection of large-scale systems, data platforms, and modern Generative AI. With over a decade of experience across telecom, BFSI, manufacturing, security, retail, and e-commerce, he has designed and operated production systems on AWS and other major clouds, often under strict reliability, security, and cost constraints.

Deo started as an engineering graduate and later completed a master’s in Data Science and Management, giving him a rare combination of deep systems engineering and solid foundations in statistics and machine learning. Over the years he has led large technical teams, closed multi-million-dollar cloud deals, and been hands-on with everything from Software Engineering to Data Engineering , MLOps/DevOps, Artificial Intelligence and GenAI architectures

His recent work focuses on making GenAI usable and safe in real systems, not just as a demo. He builds tools like AI Sentry (aisentry.co) for AI security and governance, AI Architecture Audit (aiarchitectureaudit.com) for stress-testing AI designs, and open-source security and infra tooling(secscan-cli) available on PYPY. He is particularly interested in probabilistic thinking, retrieval-augmented generation, tool-using agents, and metacognitive architectures—systems that “know when they don’t know.”

Deo wrote Demystifying Generative AI for the kind of engineer he works with every day: smart, experienced software professionals who are tired of vendor hype and shallow prompt tips, and who want solid mental models that connect probabilities, algorithms, and systems.
