At E2open, I developed and maintained server-side logic using Java and Spring Boot, including data mappers that transferred data between Oracle and the application layer.

I wrote JUnit tests for business logic and data mappings, and queried relational data in Oracle to support logistics operations.

As a freelancer, I managed client projects from concept and UI/UX design through deployment, using React.js and WordPress.

I also customized responsive WordPress themes and plugins and deployed web solutions, handling server configuration, domains, and ongoing maintenance.
