Over the past year, intSheep worked extensively on the yaklang/yaklang repository, building advanced static analysis and risk management tooling for code security and compliance. Leveraging Go and Java, intSheep engineered features such as SSA graph export, batch scanning via gRPC, and risk disposal lifecycle management, focusing on scalable analysis and robust data modeling. The work included deep refactoring for concurrency, dependency tracking, and test coverage, as well as integration of AI-assisted rule authoring and JSON-based data export. This approach improved reliability, reduced edge-case failures, and enabled safer, faster releases, demonstrating strong backend development and static analysis expertise.
