I contributed to the REST API for a multi-tenant education platform, working with TypeScript, Express, Prisma, and PostgreSQL. My work included request validation, authentication and role-based access control, plus contributions to API documentation and automated tests.
I built a browser-based analytics platform for CSV and Excel files, with data validation, KPI calculations, visualizations, and reports. I also built a FastAPI RAG research prototype for clinical reference questions, with source references and citation validation.
