PROFILE
Daniel Krueger
Daniel Krueger contributed to the hivemq-edge repository by engineering robust API infrastructure and enhancing backend reliability over four months. He stabilized and versioned the REST API using OpenAPI 3.0, enabling automated client code generation and smoother downstream integration. Daniel refactored polling and adapter coordination, introduced the COMBINE protocol adapter, and improved data flow reliability through TagManager integration. His work included rigorous code cleanup, annotation standardization, and migration to generator-driven workflows, primarily using Java, Gradle, and YAML. By addressing runtime stability, build automation, and licensing compliance, Daniel delivered maintainable, well-documented features that improved developer experience and system interoperability.

Mar 1, 2025March 2025 (2025-03) - hivemq-edge: Delivered Release Candidate RC 2025.6-SNAPSHOT by upgrading all modules to 2025.6-SNAPSHOT and introducing the OpenAPI 3.0 schema for the HiveMQ Edge REST API (versioned 2025.6-SNAPSHOT). This establishes a stable API contract for clients, enabling automated client code generation and smoother integration with downstream systems. The changes are captured in two commits: 8487621ee8d3fc48fd89604e98d12ecabc112ef8 (version bump) and 4930b30f7085fc036655d1d11d6df8002738f521 (add OpenAPI for 2025.6-SNAPSHOT). Overall, improved API stability, client onboarding readiness, and release engineering governance across the hivemq-edge repository.

Dec 1, 2024December 2024 brought stabilization and API consistency across hivemq-edge. Key outcomes included substantial code quality enhancements (nullability/final/static annotations), API-domain alignment (DomainTag cleanup and removal of protocolId), improved Tag API handling (empty responses and optional fields), a refreshed OpenAPI surface with regenerated specs and updated tests, and standardized MQTT tag naming. Across bug fixes and stability patches, startup reliability, data URL parsing, and sync behavior improvements reduced edge-case risks. Versioning and OpenAPI versioning updates prepared the project for upcoming releases and ecosystem compatibility. Overall, these deliverables improved reliability, developer experience, and business value for API consumers and operators.
