Anton Weltzien developed and enhanced core Element Templates features across the Camunda ecosystem, focusing on repositories such as bpmn-js-element-templates and camunda/element-templates-json-schema. He implemented support for advanced BPMN constructs like zeebe:calledDecision, priorityDefinition, and assignmentDefinition, integrating these into template factories and validation schemas using JavaScript and JSON Schema. Anton refactored update logic for maintainability, improved validation error reporting, and expanded test coverage with Chai and unit tests. He also delivered comprehensive documentation in camunda/camunda-docs, reorganizing content for clarity and onboarding. His work addressed configuration risks, streamlined template authoring, and improved deployment reliability for Camunda users.
