Started the project with a monolithic back-end to move quickly and match early requirements. As the product grew, helped transition the system toward a microservices setup.
Set up CI/CD for the services and used GitHub Actions to automate builds, tests, and deployments.
Built backend features primarily in TypeScript, focusing on maintainability and reducing runtime errors.
Worked with Docker during development and deployment as the architecture evolved.
Used Postgres and MongoDB depending on service needs, and made improvements around performance and reliability.
Automated daily leaderboard reward distribution so rewards were calculated and delivered consistently with minimal manual work.
