Message

At The Provato Group, I maintain and release Roofing Passport’s web platform. I led its migration from .NET v3.1 to v8 and from Azure Tables to EF Core with SQL Server, tuning queries and reducing crucial everyday operations from seconds to milliseconds.

At BNSF Logistics, I developed shipment monitoring and a live carrier-capacity dashboard. At Verifone, I contributed to a payment platform and implemented Kafka-based transaction processing; on Paselibre, I developed fraud prevention mechanisms that helped bring fraud incidents to almost zero per month after release.
