Michal contributed to the golemfoundation/octant repository by engineering robust deployment pipelines and backend systems focused on stability, scalability, and security. He implemented environment-specific configurations and automated CI/CD workflows using Python, YAML, and Helm, enabling safer upgrades and streamlined release management. Michal addressed complex issues such as database migration consistency with Alembic, secure contract detection for Ethereum EIP-7702, and SQL injection prevention via SQLAlchemy. His work integrated Cloudflare proxying, improved multi-network support, and maintained compatibility with evolving APIs. Through careful versioning, infrastructure management, and backend testing, Michal delivered maintainable solutions that reduced deployment risk and improved operational reliability.

July 2025: Delivered a correctness-focused improvement to contract detection in golemfoundation/octant by ensuring EIP-7702 delegated EOAs are correctly identified as non-contract addresses. Updated the is_contract check to validate the EIP-7702 signature, aligning behavior with the EIP and reducing misclassification risks for authorization flows and tooling that rely on contract-detection results. This change enhances system reliability and security posture with minimal risk and clear auditability.
