Worked on enhancing the reliability of the AvaProtocol/EigenLayer-AVS repository by introducing comprehensive unit tests for the builder.go helper functions. Focused on critical backend flows involving user operations and paymaster requests, the approach centered on increasing test coverage to reduce regression risk and support safer future refactoring. Leveraged Go for backend development and unit testing, establishing a robust foundation for continuous integration stability. The work did not involve bug fixes but prioritized preventative quality measures, ensuring that core logic remains dependable as the codebase evolves. This effort contributed to more reliable workflows and improved confidence in ongoing development processes.
