What I'm looking for

I'm seeking a Head of Engineering (Red Team) role focused on automated attack pipelines, Kubernetes isolation sandboxing, adversarial vulnerability discovery, failure mode analytics, and machine learning operations.

At SAMSARA, I architect secure runtime sandboxes and operational guardrails with Kubernetes and Docker to evaluate adversarial prompt injections. I also lead technical evaluations of automated tool-use logs, using statistical analysis to identify vulnerabilities and enforce security gates.

I maintain async Python microservices and REST APIs that process real-time telemetry events. My work with the platform team helped reduce MTTR by 40%, and I mentor developers and participate in engineering recruitment.

Previously, I worked on high-load systems at SHOPEE and refactored legacy modules into REST API primitives at GITLAB. At BKASH LIMITED, I directed secure platform design and supervised an engineering squad; at PATHAO, I built real-time location-tracking data routers and websocket configurations.
