As co-founder of the business, I developed an algorithmic, high-frequency trading (HFT) system that executed trading strategies, processed millions of orders per day, and managed $100s of millions of market exposure in order books around the globe. Caherciveen quickly became a significant liquidity provider and participant in the secondary market for U.S. Treasury securities. • Most notably, I pioneered big data analytics capabilities that optimized execution of trading strategy and overall system performance. Not only did this system equip traders and engineers with the ability to make data driven decisions, but it was also key in positioning Caherciveen as one of the first firms in the industry to use radio signals instead of optical fiber, significantly reducing network latency. [About the company: Proprietary, high-frequency trading firm specializing in providing liquidity through algorithmic market making.]

• As Embedded Systems Architect/Engineer for Machine Bus Corporation, I led the full lifecycle electronic hardware development of multiple devices and established distributed control architectures for robotics and other intelligent machine control applications.• Having started out in consulting roles as Senior Software Architect for UBS/O’Connor and Senior Software Engineer for Chicago Board Options Exchange, I embraced ambiguity as I learned the ins and outs of capital markets early on.
