About

7 years of back-end engineering experience architecting high-availability, distributed systems for enterprise Banking and Payments platforms — currently leading engineering delivery at Capco on Visa's Payments Platform, with prior experience at NTT Data (Goldman Sachs), Wissen Technology (Morgan Stanley, Flipkart), and Cognizant. I specialize in: → Java 8/17, Spring Boot, Microservices, REST APIs, Distributed Systems, Event-Driven Architecture → System Design (HLD/LLD) for SDK/API platforms, digital card-management, and payment ecosystems → Apache Kafka, Redis, Docker, Kubernetes, AWS — building scalable, observable, production-grade systems → Technical leadership — leading engineering teams, mentoring, and owning delivery from architecture through production Selected impact: - Leading a team of 2 back-end engineers delivering SDK/API Platform capabilities for Visa's digital card-management ecosystem — improved deployment velocity and release stability by 40% - Architected secure credential-migration infrastructure (CredVault) for Goldman Sachs at enterprise scale — improved operational reliability by 30% - Re-engineered REST API integrations and reconciliation logic for Morgan Stanley — improved processing performance by 70% and reduced manual intervention by 60% - Contributed to Flipkart's cloud-native migration to Kubernetes — improved infrastructure scalability by 35% I understand the compliance, reconciliation, and reliability constraints that make payments and banking systems different from typical consumer-app engineering — and I bring hands-on production ownership across the full lifecycle: architecture, security, CI/CD, and post-release stability. I'm currently and actively looking to relocate to the UAE, targeting Senior Engineer / Engineering Manager roles in fintech, banking, or payments-focused technology teams in Dubai or Abu Dhabi. Open to connecting with recruiters, hiring managers, and fellow engineers in the UAE fintech/banking space — feel free to reach out.
