Worked on requirement, design and development of Disaster Recovery solution for VMware ESXi hosted virtual machines in Microsoft Azure cloud, used C/C++ and distributed systems design. Completed design and implementation of a crash-consistent fault-tolerant log-structured storage for staging DR data on its way to a permanent cloud-based object storage using C/C++ in a virtualized Linux appliance on X86/X64 platform. Improved system performance (I/O latency and bandwidth) more than 200% by refactoring and tuning parts of software. Led implementation of various features in the DR management server, such as automatic DR log size adjustment, Disaster runbook execution.

Skills: Debugging · Internet Protocol Suite (TCP/IP) · C (Programming Language) · Test-Driven Development · Code Review · Object-Oriented Programming (OOP) · Linux · Data Structures · Systems Design · GNU Debugger · C++ · Linux application development · Distributed Systems · Multithreading · C

Worked on Sandisk's Enterprise caching product line, a server-side caching solution designed to accelerate HDD-based storage by caching frequently accessed data on a fast SSD. Worked on the design and development of "IO filter" based hypervisor caching layer for Vmware ESXi, which implemented the disk caching algorithms. Led the development of features like cache creation, cache resize and state management based on system events like snapshot, clone, vmotion and storage vmotion. Used various kernel debugging techniques to troubleshoot problems (gdb, stack dumps) and optimize performance.
