Mikko Deriabin engineered and optimized CI/CD pipelines for the Alt-Org/Altzone and Altzone-WebPages repositories, focusing on build reliability, deployment traceability, and resource efficiency. He introduced date-based versioning and change-detection logic to streamline release management and reduce unnecessary builds, leveraging technologies such as GitHub Actions, Jenkins, and TypeScript. Mikko addressed cross-platform build challenges for WebGL and Android, implemented scheduled and manual triggers, and resolved asset integrity issues by updating metadata. His work emphasized automation, performance optimization, and configuration management, resulting in faster feedback cycles, improved audit readiness, and scalable infrastructure that supports both frontend and Unity-based development workflows.

January 2026 performance summary for Alt-Org/Altzone: Delivered a CI Build Optimization feature that skips CI builds when there are no repository changes. This targeted optimization reduced unnecessary builds, shortening CI run times and lowering resource usage, which accelerates feedback and developer velocity. No major bugs were reported or fixed this month; focus remained on performance and reliability of the CI pipeline. Overall impact includes faster delivery cycles, potential CI cost reductions, and improved engineering throughput. Technologies and skills demonstrated include CI/CD pipeline optimization, change-detection logic, Git commit traceability, and collaboration across the Altzone repository.

October 2025: Focused on stabilizing CI for Altzone-WebPages. Implemented a temporary workaround to unblock builds by removing the automation tests stage in the CI pipeline, addressing a blocking flaky-test issue. This allowed development to resume with faster feedback and preserved release readiness. The change was implemented via two commits: 3ab0920ddcad6b629097a62fdb0afc0ce45fd223 and 5c081b7f0190c2e6d5cb01a7ef9c1ef7a775647e. Next steps include investigating flaky tests to reintroduce the tests stage or implement more robust tests.

August 2025 performance summary for Alt-Org/Altzone: Focused on strengthening CI/CD reliability and deployment traceability through a date-based build versioning strategy. Delivered a standardized versioning scheme where the CI build version equals the current date in DD.MM.YYYY format, ensuring that all builds produced on the same day share the same version. This change improves deploy traceability, simplifies release management, and reduces version-related confusion in audits and hotfix cycles. The work is infrastructure/quality-focused and lays groundwork for future release automation.
