I've built MeshPay, a secure offline UPI payment network using Spring Boot and PostgreSQL, with AES-GCM/RSA-OAEP encryption, transaction idempotency, TTL-based packet validation, Flyway migrations, and simulated Bluetooth mesh communication.
I've also developed Next.js applications for smart waste management and employee leave management, and completed a JPMorgan Chase & Co. software engineering simulation building event-driven financial transaction features with Java, Spring Boot, Kafka, Spring Data JPA, and H2.
