PROFILE
Hao Wang
Over a three-month period, contributed to the HHS/simpler-grants-gov repository by delivering seven backend features focused on data integrity, security, and maintainability. Work included streamlining the database by removing obsolete tables, enhancing the data model with foreign key constraints, and introducing a flexible authentication system supporting both JWT and API keys. Leveraging Python, SQLAlchemy, and Flask, implemented structured workflow management using lookup tables and enums, while expanding unit test coverage and updating documentation to support deployment and governance. The approach emphasized reducing technical debt, improving operational risk, and laying a scalable foundation for future automation and access control enhancements.
