Over seven months, Dovhanych engineered robust CI/CD automation and release workflows for the trezor-suite and trezor-firmware repositories, focusing on reliability, security, and traceability. He automated emulator and cross-platform binary builds, streamlined artifact distribution using AWS S3, and enhanced release governance through metadata management. Leveraging GitHub Actions, Bash, and YAML, Dovhanych migrated authentication to OIDC and GitHub App tokens, reducing operational risk and improving access control. His work included bug fixes for CI reliability, optimized change detection, and enabled private repository builds, resulting in faster feedback cycles and reduced manual intervention. The solutions demonstrated depth in DevOps, scripting, and release engineering.

April 2025 monthly summary: Delivered automated release improvements and security-focused CI/CD enhancements across trezor-suite and trezor-firmware, driving faster, more reliable releases and stronger access control. Key features include: streamlined staging release workflow by removing AWS credential and suite-production gating for autoupdate test uploads; creation of browsable release artifacts in S3 release storage for easier discovery; and a comprehensive overhaul of CI authentication using OIDC and GitHub App tokens to replace user tokens. In firmware, CI authentication and token management moved to GitHub App integration, with fixes to token generation and environment variable handling to improve reliability and repository synchronization. Overall impact includes reduced release friction, lower operational risk, improved security posture, and clearer visibility into artifacts. Technologies/skills demonstrated include GitHub Actions, OIDC, GitHub App tokens, CI/CD automation, AWS-free staging workflows, S3 artifact indexing, and environment variable governance.
