What I'm looking for

I'm looking for a senior software engineering role where I can apply Java back-end development, microservices, cloud technologies, enterprise modernization, and distributed-systems experience to scalable applications and technical problem-solving.

I've built and modernized enterprise platforms for Palo Alto Networks, RBC Bank, Scotia Bank, CIBC Bank, Volvo Truck, Oracle, TE Connectivity, and IKEA. Most recently, I engineered Java 21 and Spring Boot microservices, REST APIs, GraphQL endpoints, GCP Pub/Sub workflows, and Salesforce, SAP, and cloud-marketplace integrations for Palo Alto Networks' licensing platform.

Across 8+ years, I've improved payment transaction speed by 30%, system performance by 25%, and operational overhead by 40%. I work across Java, Spring Boot, cloud platforms, messaging, databases, CI/CD, and distributed systems, and have led a 12–15-member technical migration team.
