I build high-performance Java, Kotlin, and microservices platforms for banking, retail, and mobile applications.

I've delivered Java and full-stack software for GlobalLogic, Cognizant, Tata Consultancy Services, and Algoworks, supporting clients including Verizon, JPMorgan Chase, SBICARD, and USU.

At GlobalLogic, I optimized Verizon APIs through atomic migration with Adobe Experience Manager and built scalable Kotlin microservices using Docker, Kubernetes, GraphQL, and Swagger. I also improved CI/CD workflows with GitLab and Jenkins, reducing deployment friction by 30%.

I've led legacy banking data migration for JPMorgan Chase with Core Java and Oracle SQL, maintained 99.9% availability for SBICARD applications, and built the ANEWU Fitness Android app from scratch.
