What I'm looking for

I seek senior technical leadership roles where I can lead engineering teams, design scalable cloud-native systems, apply AI/automation, and drive measurable cost and performance improvements.

I am a results-driven Technology Director with over 15 years of experience leading engineering teams, architecting microservice-based systems, and delivering cloud migrations that cut costs and improve reliability. I have led cross-functional teams to build core services (authentication, file storage, messaging, payments), implemented near real-time analytics, and deployed AI-powered automation that dramatically reduced errors and processing time.

My work includes achieving a 30% reduction in AWS costs by moving from EC2 to Kubernetes, designing an automated invoice-processing system that reduced human error from 4% to 0.3%, and building high-throughput file services handling 150 TB and 250 uploads/sec. I prioritize scalable architecture, operational efficiency, and practical use of AI to drive measurable business outcomes.
