Dr. S. Ravi Shankar is a technocrat with over 30 years of experience (post Ph.D.) in designing, developing, and operating large-scale and complex products, and managing businesses that leverage technologies such as Io T, distributed systems, Artificial Intelligence, and autonomous vehicles such as drones, for operational efficiencies and resilience, resulting in both top and bottom-line growth.
I have extensive experience in leading product development and management teams across 4 continents, multiple markets, and sectors (telecom, transportation, healthcare, and fintech).
I bring to the table pragmatic insights gained from my experience in leadership positions. I have managed revenue streams in excess of USD 100 Million and created award-winning products (e.g., TMC Magazine’s Internet Telephony Product of the Year in 2002). I have founded four, and advised/mentored over 30 start-ups.
I am the inventor of Po MA (Proof-of-Match Adaptive), a fast, fair, and quantum-resistant leader-election mechanism for high-speed blockchains. I am also the inventor of a trust model that works with Po MA to realize a high-speed consensus mechanism that is Byzantine Fault-tolerant and has an extremely low executable footprint. I have several patents in various stages of processing. I have included below the links to two recent patent filings.
