Context: HealthTech startup; early hire; platform work on PTHD (RWE) and EDA (Data API). Highlights - TypeScript migration: consolidated a fragmented codebase and led JS → TS conversion (backend). - PTHD (RWE Web & Mobile): designed SoE/Scheduling (visits → milestones → tasks; statuses: draft / submitted / locked; CRON updates). - eCRF/ClinRO (HIVE): integrated forms with a rules engine (visibility, validations, pre-fill), plus audit trail and permission management. - Data ingestion: built FHIR/HIVE pipelines via RabbitMQ; added Fitbit integration. - EDA (Embleema Data API): REST for PTHD read-replica MongoDB extraction with DTO → OMOP mapping (JSON/CSV); paginated/filtered endpoints; OpenAPI/Swagger docs; observability (Winston/Sentry); Keycloak security. - Security / Quality: Keycloak (OIDC) SSO, SonarQube quality gates, tests (Jest / Vitest / Cypress), CircleCI. - Study Designer (SD): Java → TypeScript migration and full integration into PTHD. Stack: React, React Native, TypeScript, Vite, React Query, Formik/Zod, Node.js/Express, MongoDB/DocumentDB, RabbitMQ, Keycloak, Jest/Vitest/Cypress, PM2, CircleCI, Swagger/OpenAPI, Winston, Sentry, @mikro-orm/mongodb, Docker.
