01 About

I build AI automations and agents that take real work off people’s plates — and the fast, reliable systems underneath them: Python and Node.js services talking over gRPC, Kafka and RabbitMQ, on Kubernetes I design and operate myself.

Full stack engineer with 5+ years in production across healthcare, e-commerce, automotive and consumer apps. I’ve led a 20+ microservice healthcare platform from requirements to Terraform-managed GKE environments, led backend teams of up to six engineers, and cut server response times by ~40% through Redis caching and database optimization.

Today my focus is AI and DevOps: agents and automation pipelines wired into real business workflows, LLM-powered document extraction, and integrations with Kimi, Hume AI and AssemblyAI — shipped through infrastructure as code and CI/CD. CKAD certified, with working knowledge of Go.
