5+ years building full-stack platforms and data systems

I build full-stack web applications, backend services, and data pipelines that power production products. My work covers API design, database architecture, ETL and data flow reliability, cloud infrastructure, and frontend systems that deliver fast, maintainable user experiences.

2+ years building AI workflows for businesses

I design and ship AI workflow solutions that reduce manual work across operations, support, and internal tooling. This includes LLM-powered automations, retrieval and prompt pipelines, and AI integrations that turn business processes into reliable, measurable workflow systems teams use every day.
