Over a 20-month period, contributed to the signal18/replication-manager repository by architecting and delivering a robust platform for database replication, backup, and cluster management. Leveraging Go, React, and SQL, the work spanned backend API development, frontend UI/UX, and infrastructure automation. Implemented features such as Restic-based backup orchestration, OpenSVC integration, and granular access control, while enhancing reliability through concurrency management and comprehensive error handling. The approach emphasized modular design, test coverage, and observability, resulting in scalable, secure workflows for MySQL/MariaDB deployments. Continuous improvements to configuration management, logging, and deployment tooling enabled safer operations and streamlined developer and operator experience.

Dec 1, 2025December 2025 — consolidated improvements across Restic task orchestration, cluster replication and failover, and core monitoring, delivering stronger backup reliability, safer failover, and improved observability. Key outcomes include RESTIC task queue API endpoints (resume, pause, cancel, move) with FetchTask integration; FetchTask invocation enhancements across AddBackupTask, AddPurgeTask, and AddUnlockTask, plus a deferred FetchTask invocation in InitRepo to improve task management. Cluster replication and failover enhancements provide refined ChangeMaster options, backup-recovery retry counts, and corresponding UI/configuration improvements for MasterRetryCount. Backup flexibility expanded with SFTP support via backup-restic-local-repository configuration. Core Schema Monitoring was consolidated across the cluster, delivering master-slave comparison, API endpoints, scheduler integration, and UI support with improved error handling and configuration flow. A centralized logging mechanism was introduced with Pushover integration to standardize log messaging and alerting. Supporting UI and metrics work includes frontend refactor cleanup and renaming metrics handling (FetchStats).

Dec 1, 2024December 2024 (signal18/replication-manager) delivered security, reliability, and onboarding improvements at scale. Key features delivered include: GitLab login support with ACL-based shared clusters view; Admin-only global settings access; peer API handling with token persistence; automated log directory creation for error_log and slow_log; onboarding enhancements including peer registration UI, registration email, and success text notification. Additional improvements included CORS hardening (setting Access-Control-Allow-Origin to '*'), logout token removal, and governance-oriented changes such as enforcing verified GitLab emails for peer access. Major bugs fixed include: fixes to ensure consistent peer cluster list display after the patch (peer list bug fixes); race-condition fix when initializing privileges to prevent access-denied for generated keys; graceful error handling for failed read responses; 404 handling for peer requests; and cleanup preventing keys from being stored in git. The month also laid groundwork for better performance and observability (reduced pull frequency; enhanced logging/monitoring; and deployment hygiene). Overall impact: increased security, multi-tenant readiness, improved developer and user experience, and stronger reliability. Technologies/skills demonstrated include OAuth/GitLab integration, ACL/RBAC refactoring, token lifecycle management, CORS configuration, concurrency/race-condition handling, proactive logging/monitoring, and config/service plan management.
