At PAY10, I work on a wallet banking fintech platform, developing wallet-to-wallet, wallet-to-bank, and bank-to-wallet transaction flows. I added refund validation, reconciliation, and Kafka-based event handling to improve transaction reliability and prevent race conditions.
I also implemented wallet transaction history and ledger modules, and built secure communication between microservices using JWT tokens. My work includes customer and merchant risk assessment, wallet footprint tracking, and configurable withdrawal rules.
At TEMENOS AG, I worked in R&D on the Wallet Manager product, contributing to system design, backend development, and product enhancements. I developed Java applications and REST APIs, and worked on integrations using Apache Camel.
Across these roles, I've worked on payment processing, database performance, testing, and production support. I'm AWS Certified as a Solutions Architect, Developer, and SysOps Administrator.
