What I'm looking for

I'm looking to build backend, integration, or AI-driven systems where I can improve production performance, work with Java and Python, and grow through cross-functional engineering challenges.

At Oracle Financial Services Software, I develop and enhance production banking integration services that support transaction and service workflows.

I've built Business Services, Proxy Services, transformation pipelines, and Java Callouts using Oracle Service Bus, WebLogic, XQuery, NXSD, and Oracle Database. I also optimized a database integration from a 20-minute response time to a few seconds.

I led development of a client-facing log monitoring and analysis system with Spring Boot, REST APIs, JPA, and Maven, enabling transaction-level investigation of failures and bottlenecks. Alongside client work, I contribute Python and FastAPI backend components to a cross-functional AI initiative on OCI.

My projects span a microservices banking platform and a generative AI diabetes management tool, where I developed machine-learning models for risk classification and glucose prediction and integrated GPT-3.5 Turbo for personalized recommendations.
