PROFILE
Henry Heikkinen
Worked on the Opetushallitus/viestinvalityspalvelu repository, delivering features that enhanced infrastructure reliability, security, and developer experience. Over five months, implemented environment-aware DNS management, automated dependency updates with Renovate, and improved CI/CD pipelines using AWS CDK and GitHub Actions. Addressed security by enforcing npm install best practices and integrating vulnerability alerts, while also refining Lambda permissions and SQS reliability for robust backend workflows. Improved developer tooling with dynamic tmux session naming and clarified build logs through Maven batch mode. Used TypeScript, Shell scripting, and YAML to automate processes, streamline deployments, and ensure maintainable, auditable changes across cloud environments.

Mar 1, 2026March 2026: Delivered a security hardening feature for Opetushallitus/viestinvalityspalvelu by adding ignore-scripts to npmrc, ensuring npm install does not run lifecycle scripts. This reduces the attack surface and strengthens the security baseline for dependency installation. Commit 4ecd75fabcdea501beb975f816cfa7827f099c7f ('Add ignore-scripts true to npmrc'). No critical bugs fixed this month in this repository. Impact: improved security, safer deployments, and a clearer, auditable change. Technologies: npm configuration, DevSecOps practices, configuration-as-code.
