Hi, I'm Picklu Paul

Engineering leader, author, speaker and consultant
who is passionate about driving AI security
and DevSecOps at scale.

About Me

I'm a Engineering leader, author, and consultant with 10+ years of experience building and scaling AI security, DevSecOps, and platform engineering teams. At Grab, I lead AI security—developing an LLM-powered triaging engine and establishing AI guardrails, cutting false positives by 85%. I've led security and infrastructure functions across AWS, GCP, and on-prem, with hands-on expertise in Python, Kubernetes, Terraform, and GitOps. As the author of Demystifying DevSecOps in AWS and a keynote speaker at executive conferences in Singapore, India, Indonesia, and Thailand, I bring a strategic, hands-on approach to scaling secure, high-impact systems.
