About

I’m a senior/lead full-stack engineer with 10+ years building scalable, cloud-native web platforms end to end—from architecture and secure authentication to production operations and reliability. I’ve led delivery of microservices on AWS and improved performance and throughput using Kubernetes, CI/CD, and strong observability practices.

I also integrate AI capabilities into real workflows, using LLM-powered automation, retrieval (RAG), and human-in-the-loop review to reduce operational load while maintaining safety, traceability, and governance. I enjoy turning complex system needs into dependable services, tightening security with OAuth2/OIDC and JWT patterns, and partnering across teams to ship faster with confidence.
