• I was involved in the architecture team of Finacle, Infosys . My work was to incorporate latest technologies & enhance the quality of the existing product.
• o Design and Develop Memory Leak Detection tool for C/C++.
• This tool required overriding of system-calls (malloc, calloc, free etc) & user-defined functions, storing the information in a Hash-list and printing the detailed leak report at run-time with least effect on the performance of the actual process. The report depends on the amount of information present in the executable or shared objects(upto 10 levels of backtracking).The tool was made for OS type Hp ,Sun ,Aix separately.
• o Heap Optimization for Caching.
• DB statement caching lead to better performance but considerably increased the Heap-size. Some critical Algorithmic changes were done to improve both the performance & the Heap growth.
