October 2025 monthly overview: Cross-repo stability improvements and CI/CD enhancements focused on deployment reliability and integration readiness. In keboola/keboola-as-code, ETCD compatibility and version alignment were improved: legacy ETCD image reintroduced to support older provisioning workflows, and ETCD updated to 3.6.2 across docker-compose and docs to maintain version consistency. In keboola/mcp-server, release workflow improvements and agent-specific tagging were implemented to enable safer canary and production deployments, and Devin AI API domain was added to the well-known domains allowlist to support future integration. These changes reduce operational risk, shorten release cycles, and demonstrate proficiency with Docker Compose, ETCD version management, CI/CD workflows, and domain allowlisting.

July 2025 focused on delivering robust event-driven capabilities and stabilizing core Keboola repos. Key features delivered include MCP-side event dispatch integration in the MCP context, an MCP server version upgrade, integration of event triggers in the tool_errors decorator, and the addition of integration tests for tool execution. In keboola/keboola-as-code, we implemented backward-compatible config parsing enhancements for orchestration IDs and dependsOn, strengthened Linux build/release reliability by ensuring the GPG tool is present, and added handling for empty remote table downloads along with tests. Major reliability and quality improvements were achieved across both repos, including updates to mocked client events and MCP context usage, code linting to flake8 standards, timezone-based instead of UTC handling, removal of certain REST-endpoint usages, and extensive test alignment. Overall, these changes improve production readiness, reduce release risk, and enable more predictable, event-driven workflows. Technologies/skills demonstrated include Python, pytest, flake8, CI/test automation, event-driven architecture, mocking and test coverage, encryption context enhancements, timezone handling, and security tooling (GPG) in Linux release processes.
