Driven by a passion for cutting-edge technology and high-performance systems, I thrive on tackling complex challenges and contributing to the advancement of modern storage solutions.With over 10 years of experience developing high-performance storage solutions, I specialize in designing, optimizing, and maintaining Linux device drivers (Kernel Mode and Usermode SPDK) for Fibre Channel-SCSI and NVMe (FC-NVMe) storage adapters. My key strengths include:• Storage Protocols & Hardware: Extensive experience with Fibre Channel (FC), NVMe over Fabrics (NVMe-oF), FC-SCSI, and writing Linux device drivers for FC-NVMe storage adapters (Host Bus Adapters). I possess a deep understanding of how drivers interface with hardware and firmware, ensuring seamless communication and optimal performance.• SPDK & Userspace Frameworks: Skilled in writing high-performance, user-space storage applications using the Storage Performance Development Kit (SPDK) for improved efficiency and low overhead. • Linux Kernel Expertise: Comprehensive knowledge of the Linux kernel, including memory management, process management, process scheduling, interrupts and synchronization techniques. I am well-versed in working with low-level kernel components to deliver high-efficiency drivers.• Programming & Multithreading: Proficient in C programming and data structure , with expertise in multithreading, inter-process communication (IPC), and multicore programming for maximum performance and scalability.• Scripting & Automation: Skilled in Bash and Python scripting to automate processes and enhance development workflows.• Debugging & Profiling Tools: Strong experience with tools like GDB, Valgrind, Medusa, FIO, IO meter, XGIG FC Trace Analyzer, Sanblaze, and Jammer to debug and optimize storage systems and device drivers.• SDLC & Version Control: Full involvement in the Software Development Life Cycle (SDLC) and proficient with tools like Git, Gerrit, JIRA, and Klocwork for code quality and project management.

Embedded Software EngineerEpisteme Soft Pvt Ltd Sep 2014 - May 2016PROJECT SUMMARY:Title : Implementation of Routing Information Protocol (RIP). Environment : C, Linux. Tools used : GCC Compiler Description: The Internet is a very large network where millions of computer systems are interconnected. In this the IP protocol operates at layer 3 and takes care of end-end routing of packets. This is done by employing devices called Routers. Routers all over, whether inside an autonomous system or outside have to exchange information about the routes known to them with their neighbors and eventually construct the so called Routing Table. The RIP is one of the early routing protocols, implemented in TCP/IP. It is simple, most fundamental and is used to route the packets inside an Autonomous system. This project is an attempt towards the study, analysis of RIP. Implementation of Distance-vector algorithm used in RIP to calculate the shortest routes. Implementing the RIP updating algorithm which explains how a new update is to be processed by the router, how the real-time data is packetized and sent over IP.Responsibilities:• Designing and Implementation of Ripv1 Functionality.• Debugging Using GDB debugger.
