These are illustrative scenarios based on common SMB operations — not specific past clients. Each shows the bottleneck, the architecture we'd reach for, and the tradeoffs behind the call.
Operators copied shipment data between four carrier portals every morning. Errors and 24–48h reporting lag.
Built a FastAPI gateway that pulls each portal on a schedule, normalizes shipments into a single schema, and pushes status updates back. Background workers handle retries; a small dashboard shows daily totals.
A custom gateway was simpler than chaining no-code tools and gave operators clear visibility when a portal hiccuped.
Finance reconciled Stripe payouts to invoices manually each month. Mismatches were caught late and slowed close.
Webhook listener captures Stripe events into Postgres, a nightly job reconciles them with invoices and surfaces mismatches in a review queue. Slack notifications for anomalies.
Direct webhook ingestion plus a small review UI was cheaper than buying another finance tool.
Sales lived in HubSpot. Delivery lived in an internal Postgres app. Status updates drifted apart.
FastAPI service syncs both directions on a schedule with conflict resolution rules. Field-level mapping is stored in config so non-engineers can adjust.
A real service with conflict logic was more durable than two-way Zaps that fought each other.
