PROFILE

Ghislain Cheng

Ghislain Cheng enhanced deployment reliability and observability for the zama-ai/fhevm and zama-ai/kms repositories by developing and refining Helm chart configurations. He improved smart contract deployment workflows by implementing idempotent checks, optional post-deployment verification, and controls to prevent unnecessary redeployments, leveraging Kubernetes features such as nodeSelector, tolerations, and affinity for flexible scheduling. In addition, Ghislain optimized monitoring for kms-core by updating service monitor configurations and enabling image tag relabeling, which improved metrics collection and incident detection. His work, primarily using Shell and YAML, demonstrated a strong grasp of DevOps practices and contributed to safer, more maintainable deployment processes.

February 2025 (Month: 2025-02) focused on observability and reliability in the zama-ai/fhevm repository. Delivered KMS-service monitoring improvements for kms-core by updating the kms-service Helm chart: switch the service monitor from headless to ClusterIP for proper metrics collection, enable image tag relabeling, and bump the Helm chart version to reflect changes. No major bugs fixed this month; all changes enhanced metrics visibility and deployment reliability, contributing to faster incident detection and smoother releases. This work demonstrates strong Kubernetes, Helm, and Prometheus capabilities with direct business value by improving monitoring coverage and deployment hygiene.
