Over thirteen months, Brian Baalma developed and maintained the AirQo-api repository, delivering robust backend systems for air quality data management. He engineered scalable RESTful APIs and background jobs using Node.js, JavaScript, and MongoDB, focusing on reliability, security, and maintainability. Brian implemented features such as role-based access control, dynamic device status monitoring, and tenant-specific configuration, while optimizing data aggregation and validation pipelines. His work included refactoring authentication flows, enhancing caching with Redis, and improving error handling and logging. By addressing both architectural and operational challenges, Brian ensured the platform’s APIs remained performant, secure, and adaptable to evolving business requirements.

November 2025 (AirQo-api) focused on improving the accuracy and reliability of device online status signals for non-deployed and mobile devices. Delivered a targeted enhancement to the Online Status Update workflow by refactoring the job to exclude devices with a deployed status from updating the primary isOnline field. Introduced STATUSES_FOR_PRIMARY_UPDATE to clearly control which device statuses trigger the primary update, and added comprehensive unit tests covering updateRawOnlineStatus and the new constant. Alongside feature work, performed code quality improvements including cleanup of unused variables/imports and improved sinon stubs. These changes reduce unnecessary updates, enhance data quality for downstream analytics, and improve maintainability and test coverage.
