Backbone Technologies

SMEs were stitching together accounting, banking, and reconciliation manually. Backbone needed an API surface fast enough to feel like a single product, not three integrations duct-taped together.

Modular NestJS backend on AWS ECS. Plaid for bank linkage, Modern Treasury for ACH/wire, Stripe for cards. A pipeline materializes ledger events into analytics-ready facts in Postgres for ML use cases.

• ▸Bank-connectivity layer with Plaid + reconciliation jobs
• ▸Inter-bank transfer flow on Modern Treasury
• ▸Stripe payment processing with idempotent webhooks
• ▸Data pipelines feeding ML/analytics use cases
• ▸Fixed critical session bug that restored OmniArsenal to operational status

NestJS over plain Express to enforce module boundaries early; the team scaled past the point where freeform Express becomes a liability. Idempotency keys on every webhook from day one — saved us during a Stripe replay incident.
