independent systems & quant engineering

Infrastructure spec'd
like a blueprint,
not a pitch deck.

Data pipelines, trading systems, and backend architecture for teams that can't afford to guess. Scoped in writing, shipped weekly, monitored forever.

01SERVICES

Four disciplines, one engineer.

No account managers, no handoffs — the person who scopes the work writes the code.
[ 01 ]

Data & Quant Engineering

Market data ingestion, backtesting frameworks, and signal pipelines built for correctness first, speed second.

[ 02 ]

Systems Architecture

Backend design for services that need to stay up: clear boundaries, typed contracts, failure modes planned in advance.

[ 03 ]

Trading & Ops Automation

Broker API integrations, scheduled strategy execution, and monitoring that warns you before something breaks.

[ 04 ]

Functional-first Backend

Python and Haskell-influenced design: pure functions where it matters, tests that document behavior.

02APPROACH

Three phases, fixed order.

Each phase ends with something you can inspect, not a status update.
01

Scope

1–2 WEEKS

We define the problem in writing — inputs, outputs, and what "done" means — before any code exists. You approve the spec, not a vibe.

02

Build

WEEKLY DELIVERY

Working increments ship every week, not a black box that appears at the end. Tests ship with the code, not after it.

03

Operate

ONGOING, OPTIONAL

Monitoring, alerts, and a direct line if something needs attention at 3am. No ticket queue in between.

03STACK

What's actually under the hood.

Python SQL / Postgres Haskell Pandas / NumPy FastAPI Docker IBKR / broker APIs HSpec / pytest Linux / bash Git
04FOUNDER

One engineer, no middlemen.
