About

I'm a technology strategist and software architect with over 14 years of experience working with blockchain systems. I'm currently the Head of Solutions Engineering at Turnkey where I offer web3 security and key management advice to leading financial institutions and blockchain protocols. I've previously consulted for prominent clients including Toyota, Verizon, and Thomson Reuters. Outside of Turnkey, I educate on blockchain technology as a lecturer at UT Dallas and as a public policy advisor on the Board of the Texas Blockchain Council. Early in my career, I formed the first blockchain consultancy in the DFW area and have worked as a technical consultant for corporate clients. I co-founded the Blockchain Club at UT Dallas and later as President I built it into a hub for curating software development talent and blockchain research. I've since served as a fractional CTO, building development teams for local firms and speaking on blockchain technology at nationwide conferences. I've served in multiple roles in past projects as a manager, developer, architect, and blockchain subject matter expert. I'm also certified in agile methodologies, enterprise blockchain development, and supply-chain systems.
