Created online tool to transform CSS Selectors to XPaths powered by my java-cssSelector-to-xpath OSS and deployed on Google Cloud Platform.

Built Spring Boot application to provide REST services and render React front-end (Summer 2020).

Wrote Selenium tests that verified website functionality across Chrome, Firefox, and Edge browsers. Tests validated OSS converter by locating the same web elements using CSS Selectors and XPaths.

Website receives on average 350 users from 50 countries each month, per Google Analytics.

Rebuilt and redesigned website with ReactJS, Typescript, and Material-UI. Used lessons learned from first iteration to improve usability (Summer 2020).

Developed Open Source Software (OSS) written in Java to convert CSS Selectors to XPaths.

Utilized Java regex and recursion to efficiently validate and parse input CSS Selector Strings.

Implemented 23 JUnit tests and over 520 individual test cases, achieving 95% code coverage.

Integrated Travis CI with GitHub to provide a continuous integration pipeline.

Added conversions for 4 complex pseudo-classes, as requested from users (Summer 2020).
