Message

At Moniepoint, I architect and maintain Java and Spring Boot services for financial operations across distributed infrastructure. I implemented Outbox and Saga/Choreography patterns to address dual-write issues and support data consistency.

I also designed REST APIs and asynchronous payment pipelines, and introduced Redis and Caffeine caching alongside query optimizations. I led the Elasticsearch setup, including index creation, rollover policies, and schema management.

At Cloudcard Inc., I led development of the CloudCard Express Portal for client onboarding and API testing. I also engineered backend services for synchronizing API Gateway keys into AWS Cloud.

Earlier, I developed Java and ISO 8583 transaction-processing services at i2c Inc. and backend software for banking and FinTech clients at RedMath Pvt Ltd. At Al Khawarizmi Institute of Computer Science, I built a real-time computer vision application for human detection, emotion recognition, and age estimation.
