Message

At Drivetrain AI, I made the Dynamics 365 Business Central ERP stream incremental, cutting a nightly sync from 4–8 hours to about 47 minutes. I also investigated slow sync runs across tenants and fixed a race condition that had left connector checkpoints stuck.

I built an in-house UKG Ready HRIS connector and an Amazon Selling Partner API connector, and extended the Go calculation engine with row-preview and drill-down APIs. I also shipped per-tenant reruns on the ops dashboard and built a triage agent that turned failures across 33 tenants into 5 alerts.

At ZoloStays, I developed the ZoCare backend and shipped REST APIs in Node.js and Go. I also designed a distributed ID generator and an event-driven Kafka pipeline; the ZoCare work cut support resolution time by 30%.
