Message

At Moniepoint India, I build card-payment routing APIs and administration workflows for Aptent, including merchant routing, interchange priorities, and searchable configuration history. I also improved routing resilience with layered caching and worked on safeguards for reversals and refunds.

Previously, I delivered checkout and payment features for Zooplus at Intellias, and built payment, marketplace, and contact-center services at Globant Solutions. Across banking, insurance, compliance, and payments projects, I’ve worked with Java and Spring Boot alongside Python, React, Kafka, and cloud platforms.
