What to do:

• Design and extend transpiler/compiler components (ANTLR4 grammars, lexers, parsers, AST/IR models) that translate legacy Natural source code into modern Java (Spring Boot) applications, ensuring generated output is correct, idiomatic, and enterprise-architecture compliant.

• Develop and maintain the translation pipeline in Java: AST-to-IR mappers, IR-to-Java lowering passes, code generators (Spring services, repositories, DTOs), and REST APIs that expose transpilation as a service.

• Define and validate translation correctness by writing unit and integration tests against representative source fixtures and verifying that generated Java code compiles and behaves as expected.

• Diagnose and fix defects surfaced during transpilation (e.g., malformed generated code, incorrect type or naming mappings) by tracing root causes through the pipeline

• Support build, integration,
