PROFILE
Edison Wang
Eddie contributed to the UWOrbital/OBC-firmware repository by building and refining backend systems focused on data integrity and maintainability. He developed a data access layer using Python, FastAPI, and SQLAlchemy, abstracting direct ORM calls to improve modularity and type safety. Eddie introduced typed primary keys for data wrappers, reducing runtime errors and clarifying database operations. He implemented a new callsigns data model with automated CSV migration and PostgreSQL indexing, enhancing lookup speed and reliability. Additionally, he created migration tooling and documentation, streamlining future updates. His work emphasized robust error handling, environment validation, and comprehensive unit testing for production readiness.

Nov 1, 2025Summary for 2025-11 (UWOrbital/OBC-firmware): Delivered two primary features with associated reliability improvements and validation work. 1) Callsigns Data Model & Auto-Population on App Startup: introduced a new callsigns data model, migrated existing data from callsigns.csv, and ensured automatic population of the callsigns table on startup, with PostgreSQL indexing to speed lookups. (Commits: a052725728a3a2b76a6f1ddc002d229ebedd65b4; PR #623). 2) Database Environment Variable Validation: added validation to ensure required database environment variables exist in the .env file, improving error handling and configuration reliability (Commit: c46f41555b4fcb42e59c74930fc02216d42a61f1; PR #644). Impact and outcomes: Increased data integrity for the callsigns data, faster startup and lookup times due to indexing, and stronger configuration safeguards reducing deployment issues. The work enhances reliability, maintainability, and confidence in production deployments. Technologies and skills demonstrated: Python/FastAPI, PostgreSQL, CSV processing, data migrations, environment/config validation, unit testing, and documentation alignment with PRs.

Oct 1, 2025October 2025 (2025-10) monthly summary for UWOrbital/OBC-firmware: Delivered a major type-safety enhancement by typing primary keys for data wrappers. Refactored wrappers to accept a generic PK type and standardized PKs: MainCommandWrapper and MainTelemetryWrapper use explicit integer PKs, while other wrappers use UUID. This change reduces runtime key-related errors and makes database operations clearer, enabling safer data handling and easier maintenance. No major bugs fixed this month; focus was on design and maintainability. Overall impact: improved data integrity and developer productivity through stronger typing and clearer data operation semantics. Technologies/skills demonstrated: type-safe generics, refactoring for strong typing, codebase maintainability.

Sep 1, 2025September 2025 monthly summary for UWOrbital/OBC-firmware: Delivered a new MCC Data Access Layer Wrappers and refactor of the main_commands endpoint to use the wrapper, accompanied by tests. Introduced wrappers for MCC data models to replace direct ORM calls with an abstracted data access layer, covering Commands, CommsSession, MainCommand, MainTelemetry, PacketCommands, PacketTelemetry, Packet, and Telemetry. Refactored main_commands to utilize get_all_main_commands wrapper to centralize data access and simplify maintenance.
