Typed delivery board & release gate for multi-squad product organization

Replaced chat-driven deployment threads with a typed state machine tracking change records, schema migration gates, and cryptographic audit proofs.

Key Production Metric & Outcome

Zero undocumented production deployments across 8 engineering squads; incident rollback MTTR slashed from 52 minutes to 3.8 minutes.

Stack: TypeScript Node.js 22 PostgreSQL GitHub App API Tailwind CSS

A growing SaaS engineering organization with 8 distributed product squads was managing production deployments via informal Slack threads, manual runbooks, and uncoordinated DB migration scripts. Incident forensics routinely took hours.

Problem

There was no unified system entity representing “this changeset is in production” with cryptographic links to pull requests, database schema versions, canary health metrics, and authorized reviewer signatures.

Architecture & Engineering Approach

We designed and built a lightweight internal delivery control plane:

  • Immutable Change Records: Every release candidate is minted as a typed record with associated dependency trees and pre-flight check attestations.
  • GitHub App Event Ingestion: Webhook pipeline tracking commit SHAs, CI matrix passes, and PR approval status with idempotency keys.
  • Automated Migration Fencing: Pre-deploy schema verification running non-blocking lock checks against live PostgreSQL instances.
  • Audit Export Engine: Instant compliance export generating signed JSON-LD / PDF audit packages for ISO 27001 and SOC 2 audits.

Automated Blast-Radius Isolation & Canary Fencing

The release control plane continuously evaluates live error-budget burn rates across Kubernetes ingress nodes. If a newly deployed container image triggers a 0.05% spike in HTTP 5xx responses or unexpected database lock wait spikes (> 150ms), the gate automatically initiates zero-downtime rollback fencing without requiring human operator intervention.
