I engineered a payment integration system using Java, Spring Boot, and a two-service microservices architecture. I implemented payment validation, transaction processing, and payment-status management, while separating PayPal provider operations from core payment processing.
At HulkHire Tech, I developed backend applications and designed RESTful APIs for integration between services and external payment operations. At LastMinute.com, I built Excel-based operational dashboards that reduced manual reporting effort by 30%.
