Lead fullstack engineer at Randall Mechanical who built an internal React component library and AI knowledge assistant.

At Randall Mechanical, I own fullstack delivery for internal operations tools, from React and TypeScript interfaces to Go services on GCP. I built a component library used as the base for new internal tools and an AI knowledge assistant that draws on equipment manuals and past job notes.

Previously, I built scientific workflow applications at Thermo Fisher Scientific and customer-facing web apps at Sunbase. My work has included breaking monoliths into microservices, moving services to GCP, and building data pipelines for BigQuery.
