PROFILE
Eugene Buldakov
Worked on the LedgerHQ/actions repository to automate and secure CI/CD workflows for hardware testing environments. Delivered features such as Speculos orchestration in GitHub Actions, enabling scalable, repeatable test setups with configurable runner options and extended AWS IAM role durations. Improved reliability by refining readiness checks, standardizing environment variables, and enhancing workflow reproducibility. Hardened security by migrating sensitive CI inputs to GitHub secrets, reducing exposure risk. Strengthened ingress routing by adopting the traefik-trusted class for better traffic control. Leveraged skills in AWS, Kubernetes, and Shell Scripting, with changes implemented in Bash and YAML to support robust, maintainable DevOps pipelines.

Mar 1, 2026March 2026 — LedgerHQ/actions: Strengthened ingress routing and security by migrating to the traefik-trusted class, enabling tighter control over inbound traffic and reducing misrouting risk. The change is documented in commit 1d7fc1ec8f8f175c83d3a6216a7b5a0c5be34d23 with PR reference (#467). No major bugs were fixed this month; focus was on configuration hardening and preparing for secure, scalable deployments. This work demonstrates hands-on capabilities with Traefik-based ingress, security best practices, and concise, commit-driven delivery.

Nov 1, 2025Led a security hardening improvement in LedgerHQ/actions by migrating sensitive CI inputs (seed, speculos_role, speculos_cluster) from workflow files to GitHub secrets, reducing exposure risk in CI configurations. Implemented via a focused change linked to TSDINT-990 (commit 9d11f0f856b24780e7045e2ab6ba578b1320875f). Result: stronger secret management with no user-facing changes and minimal CI disruption.

Oct 1, 2025October 2025 — LedgerHQ/actions: Delivered reliability and reproducibility improvements for Speculos integration. Fixed readiness checks to prevent indefinite deployment waits by capping curl retries and correcting the ingress readiness loop, reducing CI flakiness. Introduced configurability for Speculos workflow: made speculos_version mandatory input for start-speculos and configured the AWS region via environment variable to standardize testing environments. These changes enhance automation reliability, reproducibility across environments, and faster safe releases.

May 1, 2025May 2025 summary for LedgerHQ/actions: Delivered automated Speculos CI/CD orchestration and environment management, enabling scalable, repeatable hardware testing in GitHub Actions. Implemented start/stop of Speculos with runner configuration options (public vs dedicated), enhanced seed handling, and extended initialization scripts. Migrated management to Speculos runners and hardened workflows; updated templates and run_id handling to improve reliability. Increased AWS IAM role duration to 6 hours to support longer test environments. These changes improved CI reliability, reduced manual setup, and accelerated feedback for hardware testing.
