At Perfios (Karza Technologies), I delivered $700K+ in cumulative cost savings through threshold-based source switching, caching, and retiring redundant infrastructure. I also standardized shared service code across 200+ production APIs.

I built reliability improvements for the KYC platform, including multi-region disaster recovery and monitoring that reduced incidents from 12–13 a week to 2–3. Earlier, at InTimeTec, I converted a manufacturing client's .NET desktop operations tool into an Angular web platform and built six new modules.
