Concise monthly summary for 2025-04 focused on the hiero-mirror-node repository. No new features delivered this month; primary work centered on stability and environment reliability. Major bug fixed: Docker Compose volume ownership/permissions issue by enforcing UID/GID 1000 for app-config across services, resolving volume permission errors in local and CI contexts. This fix involved applying the commit 524abaea0cc6f63268c5ba7578e0c51a6f35a036 and ensures consistent access rights for mounted configuration. Impact: eliminates permission-related failures, simplifies developer onboarding, and improves reliability of local development and CI pipelines. Technologies/skills demonstrated: Docker, Docker Compose, UID/GID mapping, volume permissions, debugging, patch management in a monorepo context.

January 2025 monthly summary focusing on the ERC-20 test suite refactor in hashgraph/hedera-smart-contracts, improving test dependencies, organization, and CI reliability. The work strengthens release readiness by clarifying dependencies and structuring test groups for maintainability and faster onboarding.

December 2024: Delivered development-environment enhancements in the hiero-mirror-node repo to streamline local API access and operator controls. Implemented an Nginx API proxy in the Docker dev environment to route requests to backend services (gRPC, REST, Web3) via a single entry point, reducing setup friction and simplifying local development. Expanded rate-limiting controls and messaging to enable finer operator control (lower minimum QPS from 100 to 1) and clearer feedback distinguishing general vs gas-per-second limits.
