Sep 1, 2025September 2025 highlights for masslight/ottehr: Delivered a major overhaul of the template creation/application workflow, including full template generation across all observations, deduplication of resources before stamping, batched application for performance, and a UI refresh after applying templates. Implemented global template/version governance with versioning in exam schema/config, List templates endpoint, and feature flags, plus renaming of global templates. Added telemedicine enhancements (waiting room button, candid facility naming) and expanded template capabilities (HPI handling, X-ray as a procedure type, FHIR resources scaffolding, and template expansion with fuzzy search). Strengthened reliability and testing through e2e test fixes, ICD-10 search improvements, date selector fix, and general build improvements. Expanded reporting and observability (incomplete encounters reporting, visits overview, daily payments, data table), along with task observability improvements and admin tooling. Demonstrated proficiency in TypeScript/types, EHR/FHIR scaffolding, serverless patterns, UI/UX work, and performance optimization.
