Trading infrastructure that lets small investment teams operate with confidence

I help emerging funds and systematic trading teams build reliable market-data, execution, database, and automation systems — without the cost and delay of standing up a full internal engineering group.

Let’s discuss your technology challenges

Emerging hedge funds and small trading firms often face a difficult balance: building the technology needed to operate efficiently without the resources of a large institution. An outside perspective can help — whether you’re evaluating a new trading system, designing research infrastructure, or trying to determine whether custom software is the right investment.
