Universal software architecture
Trading engines, applied AI, and fintech infrastructure — built for teams who need the thing to actually work in production.
Deterministic strategy cores, microsecond-aware routing, and backtests you can audit line by line. Trading is timing, so we built you a clock and took the case off.
Retrieval, evaluation, and tool-use pipelines wired into the systems your team already runs — with the traces and guardrails to prove behaviour under load.
Double-entry ledgers, idempotent payment paths, and reconciliation that closes to the cent every day. Sealed, tamper-evident, and it never opens by accident.
Structured traces, meaningful SLOs, and alerting tuned so a page at 3am means something is genuinely broken. Observability is an instrument, so we machined one.
Every engagement ships with a live tracker: commits, environments, burn-down, and the open decisions that need you. The only artifact with a human interface.
Five systems. One team. No hand-offs, no relay, no surprises.
We pick tools for their failure modes, not their release notes. This is what we reach for by default — and we will tell you when your problem needs something else.
Novel architecture is a liability in a payments path. We reserve invention for the parts of the system that genuinely need it.
Every engagement ships with a harness that reproduces production conditions. If it is not reproducible, it is not fixed.
No proprietary runtime, no lock-in, no rented black box. Full repository handover with documentation, on day one and at the end.
Most of our work sits behind NDAs. Here is what we can describe — happy to walk through architecture and trade-offs on a call.
Replaced a Python order router with a Rust execution core and a deterministic replay harness, so every fill could be reproduced from the raw tick stream.
Retrieval and tool-use pipeline over a decade of internal documents, with an evaluation suite that gates every prompt and model change before it ships.
Migrated a single-table balance model onto an append-only double-entry ledger with idempotent settlement and daily automated reconciliation.
Instrumented forty services with OpenTelemetry, replaced threshold alerts with SLO burn-rate alerting, and cut the on-call page volume to what actually matters.
We are engineers who got tired of watching good ideas die in delivery. No account managers, no offshore relay, no status decks — the people who scope your project are the people who write it.
We read the code, the incidents, and the roadmap. You get a written architecture review and a scoped plan — whether or not you hire us for the build.
Environments, CI, observability, and the test harness land before feature work does. This is the part most teams skip and pay for later.
Weekly demos against a live tracker. Every change is behind a reviewed pull request with a reproducible test, no exceptions for urgency.
Runbooks, architecture docs, and paired sessions until your team ships a change without us. Then we stay reachable for a defined support window.
Tell us what is broken, what is missing, or what you are trying to prove. You will get a real engineer’s reply, not a sales sequence.
