At Chemelex, I developed Angular features for TracerLynx.Next and TraceCalcPro for Buildings, tools used to design industrial heat-tracing systems. My work included component and document management features, plus insulation configuration with validation rules.
I designed database schema changes, contributed to discussions on normalization, and wrote production patch scripts for a breaking schema change. I also integrated Angular components with backend REST APIs and helped improve the interface through stakeholder design walkthroughs.
I built SyncUp, an open-source Kanban application, with a NestJS REST API and PostgreSQL transactions that prevent task-order conflicts under concurrent requests. I secured the API with JWT authentication and ownership checks, and used Claude Code to help develop the Angular frontend, tests, and project documentation.
