During a two-month period, Khánh Nguyenduy focused on backend and configuration improvements across the axonivy-market/marketplace and axonivy-market/process-analyser repositories. He enhanced the Feedback API’s robustness by refining error handling for missing users and feedback, ensuring the API returned appropriate responses instead of runtime exceptions. This work, implemented in Java and XML, improved client experience and system reliability. In the process-analyser repository, Khánh addressed project configuration issues by removing redundant resource definitions from Eclipse settings, which stabilized build and deployment processes. His targeted bug fixes demonstrated a methodical approach to API development and configuration management, contributing to healthier, more maintainable codebases.
