Daniel Cullender / CTO and founding engineer

Systems, teams, and products from zero.

I build real-time and financial platforms when the architecture still needs to be found. Currently CTO & Co-Founder at Mirador. Previously CTO at Skewacquired by Coinbase — then Staff Engineer at Coinbase and Senior Staff Engineer at Blockchain.com, with earlier low-latency trading work at UBS and Rand Merchant Bank.

Low-latency trading, risk, and execution systems

Built trading systems where latency, correctness, and risk controls sit on the critical path.

  • UBS low-latency OMS and eFX middleware
  • RMB automated cross-asset market-making, order management, and hedging
  • Blockchain.com market-making, smart order routing, execution algos, and pre-trade risk

Advisory, fractional CTO, or a hard technical problem.

I am selective about new work, but I am happy to talk when the problem sits at the intersection of architecture, product urgency, and engineering leadership.
