Systems We Shipped. Systems Still Running.

> problem

Three payment providers, no unified ledger, and reconciliation done by hand every Monday.

> approach

A provider-agnostic orchestration service with idempotent transaction records, automated retries, and a single reconciliation view.

> problem

Dispatch ran on spreadsheets and phone calls; nobody could answer where a shipment was without three messages.

> approach

Realtime tracking ingestion, a dispatcher console with live map state, and exception alerts routed to the right operator.

> problem

A decade of patient records trapped in a legacy desktop system with no backup story and no audit trail.

> approach

Staged migration with validation gates, role-based access, immutable audit logging, and encrypted backups with tested restores.

> problem

Support drowned in repeat questions while the answers already existed across scattered documents.

> approach

A retrieval pipeline over product and policy docs, grounded answers with citations, and clean escalation to human agents.
