Igor enhanced the CI pipeline for the matter-labs/zksync-os-server repository by expanding CUDA architecture support, focusing on improved compatibility and testing coverage for CUDA-enabled components. He updated the CI configuration to propagate CUDAARCHS values (80, 89, 90) through both CMake and Rust libraries, ensuring that automated tests accurately reflected a broader range of GPU environments. This work, implemented using YAML for CI/CD automation and leveraging DevOps practices, reduced deployment risks and improved feedback loops for GPU-related builds. Over the month, Igor concentrated on engineering reliability and cross-architecture testing rather than bug fixes, demonstrating depth in CI/CD and CUDA integration.

October 2025 — Strengthened CI and CUDA compatibility for matter-labs/zksync-os-server. Key feature delivered: Expanded CUDA architectures in CI (CUDAARCHS=80;89;90) with propagation to CMake and Rust libraries to improve testing coverage of CUDA-enabled components (commit ac05a35d79a194f2829bdc4682977c395001e970). No major bugs fixed this month; focus remained on CI reliability and cross-architecture testing. Impact: reduced GPU deployment risk, faster feedback loops, and higher build confidence across CUDA architectures. Technologies/skills demonstrated: CI/CD automation, CUDA architectures, CMake, Rust, GitHub Actions.
