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.
April 2026: Stability and reliability focus for the matter-labs/zksync-sso authentication flow. Resolved a critical edge case where the callback page closing prematurely before token fetch could leave users logged out, by updating the Prividium SDK to 0.15.1. This change improves session reliability, reduces login friction, and aligns with our goal of a seamless sign-in experience. Work is tracked via commit 90ec7e08dec361ab0c217ec16532e91ca5b7b16b and related PRs (m atter-labs/zksync-prividium#1020, PR #271).

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.
