Message

At Paymentology, I implemented TOTP-based service-to-service authentication and client database segregation to support multi-tenancy and compliance requirements. I also migrated service communication to HTTP REST APIs and strengthened endpoint security by moving hashing from SHA-1 to SHA-512.

At TechRivo, I developed fintech platform features with Java and Spring Boot, including document-expiration workflows and asynchronous processing with RabbitMQ. At IBM, I contributed to enterprise and banking application development and modernization, including JWT-based authentication and migration toward Spring Boot.
