May 1, 2025May 2025 - KurrentDB delivered three focused outcomes: 1) Rich log event metadata properties enabling arbitrary log properties and richer analytics; 2) Documentation cleanup and upgraded guidance with stricter certificate requirements to improve onboarding, security, and upgrade reliability; 3) CI/CD pipeline cleanup and stability improvements to reduce build failures and streamline deployments on Ubuntu runners. Business value: enhanced observability, safer upgrade experiences, and more reliable CI/CD with less developer toil. Technologies/skills demonstrated: data modelling for logs, security/compliance updates, GitHub Actions/CI optimization, Docker/runner management, and documentation discipline.
