Experience
- Participation Reportshttps://www.crossref.org/members/prep/
A simple UI for searching and evaluating scientific organizations. It includes a uniquely challenging search interface as it allows a predictive search of tens of thousands of organizations done on the front end. I used extensive performance profiling and advanced technologies like web workers to identify and resolve issues. As a result, it is a very fast, highly performant predictive search feature.
- Transpose Scholarly Records Databasehttps://transpose-publishing.github.io/
Created a web app to search through databases of scholarly journals using React Hooks. Also, I integrated with Google API to generate data from Google Sheets. Finally, I developed a custom content management system.
