Developed the Company Members Management feature for the Monolith-Station/Monolith repository, introducing a new membership schema that establishes player-user relationships and ownership status within the system. Leveraged C#, Entity Framework, and database management skills to design and implement a dedicated database migration supporting the updated schema. Addressed deployment challenges by applying an emergency Postgres migration fix, ensuring data integrity and a safe rollout. This work enhanced ownership visibility, access controls, and governance, directly improving onboarding processes and auditability for Monolith users. The feature focused on robust data modeling and migration validation, reflecting a methodical approach to backend development and system reliability.
