Helix Flag

Helix Flag lets businesses raise and check customer risk flags collaboratively — chargebacks, fraud, defaults — across a network of over 3 million records. Brigada took over the platform and hardened it into a product that ships safely.

Problem

The platform had traction but fragile foundations: no CI gate, schema drift between code and database, a signup and billing flow duplicated in five places, and a browser extension that could disagree with the web app on the same risk check.

Approach

Full audit first, then systematic hardening: CI hard gates, Sentry on both ends, end-to-end browser tests, an operations runbook, golden-record regression tests for the risk engine, and a shared verdict engine so the extension and web app always agree.

Outcome

Releases are gated and regression-tested, the risk engine catches duplicate-record flags it used to miss, and the team ships features instead of firefighting.
