My primary role includes handling customer-reported issues. As part of the process, I have to communicate with the customer to understand the case, collect logs and other data for internal reproduction. Test environment ranges from single multi-GPU system to multi-node clusters with Infiniband interconnect. Running different flavors of Linux executing applications involves machine learning framework (PyTorch) and HPC applications (GROMACS, LAMMPS, NAMD, and OpenMM). Here I have an excellent opportunity to learn different ML/DL algorithms from simple CNN/RNN to LSTM/BERT. Also, I spent time on the backend, running kernels on GPU and optimizing them. I had exposer to MPI/UCX/NCCL and other communication protocols. I was able to build custom docker and singularity images with needed packages.

Dynavisor flagship product TorrentPro is responsible for IO (Storage and network) acceleration on servers. Here I had the opportunity to work on OpenShift, OpenStack, Kubernetes, and Docker. I am responsible to set up the demo and address customer queries regarding the product.

Worked on carrier Ethernet class 80 GHz millimeter wave radio mainly used for mobile backhaul and point to point link. Work profile include development and testing of BSP of board with ARM926EJS, Xilinx FPGA and MARVEL switch. Worked of L1 and L2 protocols like MAC, VLAN, QoS, OAM/CFM, Sync-E etc. Also got involved in verification of FPGA (verilog).Key Achievement:1. Worked on U-Boot and Thread-X.2. Successfully designed software development process and implemented open source tools like, MediaWiki for collaboration, TestLink for managing requirements and test case, Mantis for bug tracking and change management system.3. Developed automation framework with automated build system to trigger build, and execute test. 4. Also developed test script using GPIB interface to create real world scenario for microwave radio using lab instrumentation.

Mainly involved in designing and developing Test Automation System. Also involved in developing test strategies, plan, and test scenarios, for exercising and analyzing quality and performance. Key Achievement: Designed and developed the automation framework for booting and running the test on multiple systems at the same time. Worked on OS Protection Profile project developing test scenarios and script for Audit, ACL, Capability & roles, User Management, Trusted management module. Participated in DO178 certification of BSP and CSP. While developing test automation executed many tests for ARINC, SNMP, SSH, SSL, CPU Power control, times, POSIX and many Hardware related analysis.

I was involved in the development of an automation system and test script for regression and performance test. Key Achievement: 1. I was awarded ownership of Solaris platform testing for TCP/IP, ICMP, VLAN, and EBO (Embedded Browser Optimization) modules. 2. Worked on Subscriber data base, RADIUS, system heath monitor. 3. Developed ethereal/Wireshark dissector for proprietary protocols analysis. 4. Developed client emulators using Perl.

Here I was providing technical expertise for designing, developing and testing of the embedded system. Most of the projects where on VxWorks and pSoS. Here I used C, gnu tools, Diab compiler, Tornado IDE and Tornado debugger extensively. And also used Bash, TCL, and Python for writing tests script. Key Achievements: 1. Participated in developing the BSP for wrSBC7457, PPC604 based board for VxWorks 5.5. 2. Participated in porting, developing and testing SSL, SSH, and IPSec protocols onto VxWorks. 3. Validated CDB89712 BSP (Strong-Arm Controller based Board). 4. Validated VxWorks BSP for Sandpoint boards (Evaluation boards provided by Motorola), supporting Processors MPC8240, MPC750, MPC755 and MPC7400. 5. Developed "software quality plans", "acceptance specifications" and "test cases (in C and Python/TCL)" for functional and performance testing for SSH, SSL, and IPsec. 6. Resolved few long-standing problems with WindRiver system's CD making software script and UDP protocol testing tool for which I was awarded.
