Full Stack Developer at Lumitech building teleradiology SaaS, including a 52-table schema and 160 API endpoints.

At Lumitech, I’m the main author of a teleradiology and medical-imaging SaaS, contributing about 70% of its API and web code. I designed its 52-table PostgreSQL schema and built 160 endpoints with role-based access control across 88 permissions.

I also built the DICOM study pipeline, including a DICOMweb proxy and OHIF viewer, and automated radiology report generation with templated worksheets. At Lumitech, I shipped rider-triggered SOS and hazard alerts that reach affected race classes within five seconds.

At Lexicon Labs, I built a consumer PWA and quiz funnel for an AI nutrition and weight-loss coaching platform. I also delivered a web application and real-time voice-chat client for a multi-tenant agentic RAG platform.
