This platform concealed complex Kubernetes details, enabling rapid product iterations with a 40% acceleration in delivery speed.Engineered Product Delivery Tools: Spearheaded the development of customer-side product delivery tools, encompassing deployment topology visualization, backup, upgrade, rollback, and log viewing capabilities, which reduced delivery time by 80% for the delivery engineers.Migrated Compilation to Tekton: Led the migration of app compilation from Jenkins to Tekton, delivering a visual pipeline platform. Integrated test coverage and security scanning, boosting Tekton's usage by 50% with significant reduction in compilation time compared to Jenkins.Introduced Pod CPU Monitoring Solution: Deployed a pod container CPU monitoring operator, automating Java thread stack printing during cpu spikes. This solution complemented Prometheus monitoring, resulting in a significant reduction in troubleshooting time.Automated Vertical Pod Autoscaler Operator: Developed Rust-based VPA generating operator. Extended VPA's functionality, leading to its widespread adoption in company Kubernetes clusters. This resulted in a significant increase in Node memory utilization, rising from ~70% to ~90%, bolstering cluster stability and eliminating the need for manual node scaling and eviction.Log Compression & Backup Solution: Developed a log compression and backup program, categorizing and storing business logs in Alibaba Cloud OSS. This reduced hot storage days for Alibaba Cloud SLS logs, translating into a cost saving of approximately ~50% for the company (across ~500 applications with daily traffic of ~10TB). Additionally, implemented log thawing and retrieval features, enabling developers to easily access application history logs.Monitoring System Contributions: Participated in the development of a comprehensive monitoring system, including error log detection, traffic anomaly detection, multi-source alarm convergence, and fault self-diagnosis.Work Order System Development: Contributed to the development of a work order system, automating the process of applying for and creating KVM virtual machines and maintenance work for applications, Alibaba Cloud ECS, SLB and other resources.
