We build the heavy systems.
Trading platforms. Logistics engines. Backends that hold at millions of messages a second. The systems other vendors quoted, started, and quietly walked away from — we ship them, on the date we said.
01The pitch
Other shops bid on the easy work. We take the jobs with real throughput, fixed deadlines, and no room for error. Senior engineers. Small teams. Shipped.
02What we build
- 01 Platforms Core systems the business stands on — trading, clearing, booking, billing. Built to carry load for a decade, not survive a demo.
- 02 Realtime systems Order flow, telemetry, pricing, dispatch. Microsecond budgets, backpressure handled, p99 measured and published.
- 03 Data engines Pipelines and stores that make a terabyte an hour feel boring. Exactly-once where it matters, cheap where it doesn't.
- 04 Rescue missions The project is late, the vendor is gone, the board is asking. We stabilize first, then rebuild — in that order.
2.1MMessages per second, sustained
A clearing platform that holds on the heaviest days.
Meridian's legacy matcher fell over every volume spike. We rebuilt the core in Rust on Kafka: 2.1 million messages a second sustained, p99 at 180 µs, and fourteen months in production without losing a single message.

A routing engine delivered on the date printed in the deck.
Ferrostar needed load planning across 31,000 daily routes before peak season — a date set in a board meeting, not an engineering one. We shipped in fourteen weeks. Fuel spend dropped 11% the first quarter.

A failed claims platform, stable in nine weeks.
Castellan inherited a half-finished claims platform and a burned-out team. We stabilized production in week one, then carved the monolith into services that hold. Incidents went from 34 a month to 2. Infra spend fell 41%.

No juniors.
No handoffs.
No bench.
Eleven engineers. Median fourteen years of experience. The people who scope your job are the people who write the code — nobody sells you a principal engineer and staffs the project with new graduates.
We don't have account managers, delivery leads, or an offshore bench. When you call, an engineer answers. It's more expensive. It's also why the dates hold.

07The number
Teams of 3–5.
From $120k.
Fixed dates.
We're not the cheap option and we don't pretend to be. You're paying for a small senior team, a fixed scope, and a date that doesn't move. Most engagements run $120k–$600k over 12–20 weeks, priced per milestone — you approve each one before the next starts.
If a day rate is the deciding factor, we are not the right fit, and we will say so on the first call.
