At Sepanta, I’m the primary backend engineer for NuStream, a multi-tenant retail loyalty and commerce platform. I replaced its polling queue with an event-driven Google Cloud Pub/Sub pipeline, cutting Display Submission time from about 15 minutes to under 2.

I architected the Display V3 rebuild, integrating a new Vision AI service and creating a Go ETL to migrate about 110 production tables from v2. I also rewrote the WhatsApp chatbot backend and connected it to the core API over gRPC.

Before Sepanta, I built backend services at Domil.io and Saman ITG for e-commerce, messaging, and gamification products. I’m also developing Verethra, a multi-tenant SaaS platform, where I’ve built identity services, custom-domain hosting, and domain services.
