Modified HAProxy (load balancer) code asynchronously to incorporate user authenticationBackend code written in C++ to handle the HTTP traffic coming from load balancerMultiple processing threads and writing threads implementationThread secure implementation of backendThe tasks require extensive knowledge of socket programming, computer networks, https/https protocols, linux and C programming. Moreover, I used GDB for debugging purposes.

It was published in Bell Labs as trade secret.The research was supported by analytical as well as simulative approach. System level simulator based on C++ was used to validate the research ideas.

Wrote MSP430 firmwares.Wrote optimized printf function for Code composer Studios.Wrote power saving examples for Ultra Low Power MSP430 advices.Black box testing of next generation ultra-low power debugging tool.Wrote test cases for FPGA implementation of 32 bit MSP432 MCU.Tested forward compatibility of existing debugging solutions with the FPGA implementation of 32 bit MSP432 MCU.

I developed traffic dimensioning tool for MSC's over Microsoft Excel through VBA scripts.Traffic segregation into calls and signalling over circuit switch and packet switched nodes was the end goal of the tool I developed.

Development of a simulation test bed for 802.11n WLAN standard in C++. In addition to that I implemented the interleaving/de-interleaving and channel estimation for the project. This experience provided my sound theoretical knowledge of OFDM and MIMO systems with a practical dimension. In addition to that programming over pipelined multi-core architecture was a great learning and challenging experience. After the project ended I shifted to GUI development for LISA tool over QT creator. LISA is… Show more Development of a simulation test bed for 802.11n WLAN standard in C++.
