About Me
I'm a Senior Software Engineer with over 10 years of experience building production platforms across geospatial analytics and fintech. My expertise spans full-stack development, AI systems integration, and cloud-native architecture.
I specialize in Python and TypeScript/Node.js, with deep experience in cloud-native delivery using AWS, Docker/Kubernetes, and Terraform. I have a proven track record of shipping LLM-powered features end-to-end, from data pipelines to APIs and user interfaces.
