TANVIR AZAD

At Visa, I lead delivery for payment-system architecture, driving more than 50% TPS growth and supporting 50K+ production transactions. I also engineered a centralized multi-tenant card service managing 500M+ cards for real-time enrollment and profile lifecycle APIs.

I lead cross-functional teams of engineers, QA, and product partners through architecture governance, sprint planning, design reviews, and delivery standards. Across Visa teams in the US and Singapore, I identify integration risks early and align distributed stakeholders.

Previously, I led backend modernization for Visa Click2Pay, built GCP-native supply-chain services at Wasoko, and developed retail, e-commerce, banking, trading, mortgage, and data-ingestion platforms. My work includes OMS, WMS, inventory synchronization, product catalog services, event-driven systems, and high-throughput pipelines processing 2M+ daily updates.

I build with Java, Spring Boot, microservices, Kafka, Kubernetes, GCP, AWS, PostgreSQL, and Oracle. I also use agentic AI workflows, MCP integrations, and automated Karate/JUnit testing to improve engineering velocity and cut regression time by 40%.
