Worked on Camunda Modeler and BPMN tooling, delivering five new features and two bug fixes in one month. Enhanced CI reliability in the camunda/camunda-modeler repository by implementing milestone creation idempotency, preventing duplicate milestones in automated pipelines. Improved user experience in bpmn-io/diagram-js by introducing opt-in multi-selection outlines, and expanded Zeebe integration in bpmn-js-properties-panel with configurable task listeners. Updated dependencies and documentation, streamlined release management, and refined GitHub Actions workflows for better build status visibility. Utilized JavaScript, Shell scripting, and YAML, applying skills in CI/CD, front-end development, and version control to increase productivity and maintain project compatibility.
