the $2m enrollment failure that changed how i think about integration

upcoming blog post

this one’s brewing — the story of how a single 834 enrollment file brought down a health plan’s member database, and what it taught me about building resilient systems.

what you’ll learn:

• why batch EDI processing without idempotency is a ticking time bomb
• the 3 AM phone call that kicked off a 72-hour war room
• how a missing segment terminator cascaded into $2M in duplicate enrollments
• the architectural patterns we built after to make sure it never happened again

stay tuned. this drops soon.
