Roop Ganguly joined Bigstream in 2017 as Lead Solution Architect, swiftly moving into his current role as Chief Solution Architect. He manages customer and partner relationships at Bigstream. Prior to joining, Roop served as a Data Scientist at Tapad and PlaceIQ. Roop has over 20 publications in the areas of fiber-optic networks, computer architecture and data science/analytics.

Keith Chapman joined Bigstream in 2016 and leads the effort in development of acceleration solutions and its integration with big data frameworks. He completed his PhD from Purdue University where he focused on transactional memory and programming language runtimes. Prior to grad school, Keith was a technical lead and product manager at WSO2 where he was involved with standardization efforts for the W3C WSDL 2.0 specification. He is also a committer and PMC member of the Apache Web Services projects.

Danesh Tavana joined Bigstream in 2018 as Vice President. Prior to Bigstream, he ran the product development team responsible for human interface integrated circuit devices. He co-founded Triscend, a semiconductor startup with $67M in venture financing, later acquired by Xilinx in 2004. Prior to that he held various positions and roles at Xilinx and NeXT Computer Inc. Danesh holds a BSEE from UC Berkeley and has 10 U.S. patents.

Shahrzad is the Director of Customer Engineering and, after the co-founders, is the first employee of Bigstream. Prior to Bigstream, Shahrzad was serving as a post-doctoral research associate at Stanford University. Before that, she was completing her graduate studies at the University of Texas at Austin.

Hardik joined Bigstream in 2018 while simultaneously finishing up his PhD at Georgia Tech. He leads the hardware acceleration team at Bigstream and is responsible for analyzing big data/machine learning/deep learning workloads, finding opportunities and architecting solutions for hardware acceleration, and designing the hardware-software interfaces to enable seamless integration with Bigstream’s Hyper Acceleration technology.

During his PhD, Hardik researched domain specific hardware architectures for accelerating machine learning, especially deep neural networks. He led the development of the very first open-source FPGA-based hardware acceleration stack for deep neural networks at Georgia Tech. His research led to several publications in top-tier computer architecture conferences. His research was recognized by the prestigious Qualcomm Innovation Fellowship (QInF) in 2018.

Upon finishing his undergrad education at IIT Guwahati, Hardik started his career at Qualcomm, India in 2013, where he worked on FPGA-based emulation of Qualcomm chips.
