# Sumit Kumar on Tal

## Headline

SDE\-3 & UPI Team Lead @ Zype Ex\-slice \| Backend & Distributed Systems \| Java · Spring Boot · Kafka · Payments \| Open to Remote

## About

I'm a backend engineer and team lead with 5\+ years building high\-throughput, regulatory\-compliant systems in fintech\. Today I lead the UPI team at Zype \(SDE\-3\), owning modules like Mandates and UDIR and coordinating with NPCI on payment reliability and compliance\. Before Zype, I spent \~4 years at Slice on core money\-movement systems — cutting the repayment flow from \~5s to under 1s \(\~5x throughput\), driving P0 API latency below 50ms, and leading our workflow\-orchestration migration to Netflix Conductor\. My toolkit: Java/Spring Boot and Node\.js/NestJS, event\-driven and domain\-driven design, Kafka, PostgreSQL, and AWS — with a strong bias toward observability, clean architecture, and mentoring the engineers around me\. I'm open to fully remote/on\-site/hybrid senior/lead backend roles\. If you're building payments, fintech infrastructure, or distributed systems — let's talk\.
