One of the first bitcoin miners; fifteen years at the intersection of energy markets and large-scale compute. Deployed 3 GW of mining and datacenter infrastructure across 21 countries. Senior Technical Advisor to the U.S. Department of Energy’s Office of Energy Dominance Financing. Hardware designer — contributor to five silicon designs and product development for U.S.-designed mining ASICs. Eight granted U.S. patents, seven on chip power control, telemetry, grid-responsive site control and device security. Four exits.

Current

Senior Technical Advisor — U.S. DOE, Office of Energy Dominance Financing04/2026 – Present

Energy and compute financing at policy scale.

  • Advise the office on economic growth, energy infrastructure, and the growing convergence of power demand and grid constraints.

Chief Revenue Officer — OBM05/2026 – Present

Go-to-market for flexible load management — grid participation as revenue.

  • Lead go-to-market and commercial operations for Foreman fleet and flexible-load management, energy analytics and settlement products — serving power suppliers, datacenter operators, bitcoin miners and other large electricity users.
  • OBM has managed 500+ MW of flexible load integrated into U.S. demand-response programs; Foreman won a 2026 Global Tech Award for Operational Technology.

GP & Founder — Alloyed Strategies

Hedge fund.

Founder — PlebSource

Bitaxe-class hardware for home miners.

Experience

Director of Product Development — Auradine2023 – 26

Advanced semiconductor design and manufacturing — U.S.-designed bitcoin mining ASICs and Teraflux systems, from silicon to fleet.

  • Seven U.S. patents granted 2025–26 (assigned to Auradine). Sole inventor of differential fleet control: tunes chip frequency and voltage across selected machines to hit aggregate power and hashrate targets without reboots.
  • Co-inventor of a device-security control that guards networked mining fleets against unauthorized changes to pool and user whitelists — hardening against hijacking.
  • Co-inventor of grid-responsive controls: site-level power plans behind a single grid meter, and phased-in power events that stagger load changes.

Partner — JAM Datacenters—

Bitcoin mining and datacenters out of Sugar Land, Texas. Sold the 14 MW Sugar Land datacenter to Truss Data Centers (09/2026).

Head of Mining — Rhodium Enterprises2021 – 24

Industrial liquid-cooled bitcoin mining at Texas scale.

  • Built and scaled the infrastructure, operating systems and commercial partnerships behind large liquid-cooled mining sites in Texas.
  • Ran flexible loads that ride the grid instead of fighting it — the kind that helped ERCOT dodge a blackout in 2023.

CEO — Mockit Esports2016 – 19

Competitive teams, events, sponsorships. Exited.

Founder — Rogue Wave Industries—

Co-inventor, U.S. Patent 8,727,951 (weight training device). Exited.

Operator — Dream Lab, Nanchang (China)—

Helped run a venture studio.
