What I'm looking for

I’m seeking a full-time backend SDE role.

At Optimum Financial Solutions, I engineered a customer-facing mutual fund dashboard and resolved production issues in Microsoft SQL Server. I also fixed a webhook handling problem in the OneMoney Account Aggregator integration to restore reliable holdings sync.

In independent projects, I architected an ERP with five Spring Boot microservices using Kafka’s Saga pattern and Keycloak OAuth2, and built a distributed banking application with Redis caching that reduced transaction latency by 40%. I’m seeking a full-time backend SDE role.
