Several Cron Jobs are still developing using spring batch • Security Audit Issue was investigated for XML injection. I have developed a algorithm to sanitize XML injection. The algorithm is inspired from Balance Parentheses Algorithm. I also wrote 50+ test cases for Junit to ensure the algorithmic accuracy. • Customizing nio multipart and transport libs multipart file parsing algorithm to support special boundary parsing and without boundary implementation. • Given opportunity to investigate memory leak issues and find out root cause why application has memory leak ,change application implementation to fix memory leak and found no issue any more and Special Characters are handle specially to support client requirements. • Migrate mulesoft middleware to webflux. 15k+ lines of codes are written but there is no any duplicate lines of codes and designed generic web architecture to maintain loosely coupling. It is highly scaleable and maintainable. It can communicate with 10 different interfaces. Customized log formation is implemented to support elastic search efficiently.Load test , performance test and concurrency test are passed successfully and also has no blockhound issue. now project is running on STG.Optimal way junits are written one method covers lots of line code coverage using parameterizeTest technique just we have to add xml test files. code coverage 97% •IDRequisition project is developed using intra mart framework which is based on terasoluna framework. • Migration Struts to Spring boot. Custom spring security was implemement. there was different roles and coresponding permission. some JSTL classes was customised to support spring boot.junits are written such way easily can covery all line writting minimum code and code coverage is 97% • Migration Spring boot 1.5.6 to 2..4 Show less
