02 What we do

Senior engineering, across the whole stack.

Strategy, design, backend, frontend, and ops sit with one team, all the way down.

01 / Platforms

Bespoke line-of-business platforms

End-to-end operational systems, built from first principles against your workflows, controls, and regulatory surface.

02 / Compliance

Compliance & audit infrastructure

KYC, AML, control attestation, immutable event ledgers, and evidence capture engineered into the architecture from the first commit.

03 / Rescues

Prototype-to-production rescues

Vibe-coded MVP that almost works? We harden it: security, observability, CI/CD, tests, and a deploy pipeline that sleeps at night.

04 / Integration

Payments, identity & integrations

Stripe, OAuth2/OIDC, Microsoft 365, Slack, regulator reporting APIs. Signed, observable, retry-safe.

03 The stack

Boring technology. Built right.

We use proven tools we have operated for years, and skip the framework of the week. Where you already run .NET, Node or Python, we work in those too.
