Developed and delivered the DDM Java Code Generator feature for the strata-org/Strata repository, enabling automated generation of Java source files from DDM dialect definitions. This work involved creating sealed interfaces for categories, record classes for operators, static factory methods, and an Ion serializer to facilitate interoperability with Lean. The implementation included comprehensive tests to validate Java compilation and round-trip conversion between Java, Ion, and Lean, ensuring robust cross-language workflows. Leveraging skills in Java, Lean, and code generation, the developer improved build and test automation, streamlined integration through tooling, and reduced manual boilerplate, accelerating development and safer refactoring processes.
