Systems that hold under real conditions.

What we do

We design and build the systems companies depend on
and cannot build for themselves.

Our specialty is automated trading and financial infrastructure — the domain where software failure is measured in money.

The problem

Most software fails the same way.
It works in the demo and comes apart under real conditions.

Real conditions mean live data, live money, adversarial markets, and no second attempt.

Lodestone Systems exists for the work
that has to be right the first time.

What we build — 01

Automated trading systems

Execution engines, market-making and arbitrage systems, and the exchange and venue integrations underneath them.

Order lifecycle handled as a state machine, not a hope.

What we build — 02

Risk and safety infrastructure

Position limits, kill switches, reconciliation against exchange truth, state recovery, live monitoring.

Built with the system, not bolted on after the first incident.

What we build — 03

Real-time data systems

Ingestion, normalisation, and low-latency pipelines.

Systems that stay correct when the feed misbehaves — because the feed will misbehave.

What we build — 04

Reliability-critical backends

The specialty is the foundation, not the boundary.

Services, automation, and integrations outside finance, where uptime and correctness matter more than shipping fast.

How we work

Four commitments.

1. 01

   Correctness before features.

   A system that is wrong quietly is worse than one that is missing loudly.

2. 02

   Proven against reality.

   Live data, real integrations, real failure modes. A passing mock test proves shape, not correctness.

3. 03

   Safety is not negotiable.

   Limits, circuit breakers, and recovery paths are part of the build, not a later phase.

4. 04

   Direct engineering.

   Clients talk to the people writing the code. No account layer, no translation loss.

How engagements work

Project first.

You bring a defined problem. We scope it, agree a clear boundary, build it, and hand it over working.

Where you want it, that continues — operating, extending, and evolving the systems we built. Continuation is offered, never assumed.
