I'm building cloud-native banking solutions for Lloyds Banking Group at Publicis Sapient, including automated reporting and data synchronization services on Spring Boot, GCP, BigQuery, Cloud SQL, and Kubernetes. I improved report processing by 20% using CompletableFuture.

Previously, I built secure investment-banking microservices for Northern Trust at EY, delivered 30+ REST APIs, and reduced reporting execution time by 35%. Across Accenture and Cognizant, I've developed Java and Spring services for mutual fund management and travel platforms while mentoring engineers and contributing to scalable system design.
