At UST Global, I design and develop cloud-native microservices with Java 17 and Spring Boot for Equifax (AltFi). I also develop RESTful APIs and build cloud solutions on Google Cloud Platform using Cloud Firestore.

I use Claude to support code generation, code review, debugging, documentation, and test-case creation. I collaborate with architects, business analysts, QA teams, and product owners using Jira and Confluence.

Previously at Infosys, I worked on enterprise projects for T-Mobile, Costco, TSC, and Advance Auto Parts. I led development teams, delivered Java and Spring backend applications, and contributed to modernizing legacy applications into microservice architecture.
