Michael Dubno (born August 23, 1962) is an American inventor, computer scientist, explorer, and video game developer.

Starting in 1984, he designed and built a robot[3] that talked, moved, had a working arm, navigated using sonar, and had an infrared GPS-like location system.

Each new type of option required new and different fields to describe them contractually and mathematically, and unlike SQL, SecDB was object oriented,[10] and designed for the task.

SecServ, the underlying home-grown datastore was a cross between an immutable ledger (think blockchain) and an object store for rapid retrieval.

SecServ was unique, at the time, because it supported replication around the globe (necessary for currency trading) and each local copy was a "master".

[8] Over time, SecDB and Slang were deployed in Goldman's other trading businesses (Equities and Fixed Income), becoming the primary risk system for the company.

[20] Dubno pioneered the use of the Internet[21] and led the creation of the GS Financial Workbench,[22] a firmwide integrated website for institutional clients.

[26] Neither firm was known for their integrated risk management platforms[27][28] and to rectify this shortfall, Dubno was hired in 2010 as the CIO of Global Markets Technology at Bank of America.

[33] Along with his brother, Emmy Award-winning news producer and technologist Daniel Dubno, "In 2002, he co-founded Gadgetoff, an organization that brings leading innovators, inventors and entrepreneurs together in an annual event that combines fun with a serious discussion of business and the future.

"[34] Gadgetoff's slogan "Bringing the smart and the useless together"[35][36] attracted presenters and attendees like TED Founder Richard Saul Wurman, Amazon founder Jeff Bezos, Inventor Dean Kamen, AI pioneer Marvin Minsky, DARPA head Tony Tether, iRobot founder Colin Angle, Longevity researcher Aubrey de Grey, Video game designer Will Wright, Architect and toy designer Chuck Hoberman.
