What I'm looking for

I'm looking for a challenging Java backend development environment where I can grow, strengthen my skills, and build on my cloud, microservices, and AI learning.

I'm building identity platform migrations at Walmart Global Tech, including zero-downtime migration for approximately 50,000 LMD drivers and B2B profile migration for 7 million US customers.

I delivered session migrations for Mexico and Canada ahead of schedule, supporting approximately 20 million users with zero disruptions.

At PayPal, I migrated a fragile legacy RPCS service to RUDCS for risk evaluation and user-consent decisions, resolved approximately 90% of SonarQube issues, and upgraded two major services from Java 8 to Java 17. I also built critical alerts across seven services and received a Bravo recognition for Two Way SMS.

Earlier, I improved resilience for IBM SVPC with Azure shared disks, implemented AWS and Azure APIs, and helped optimize Siemens MindSphere API calls by 10% while reducing AWS resource costs by 60%.
