Experience
AR Placement and Virtual Try-on
Developed a React-based app for eCommerce to improve an online shopping experience. I made it possible to virtually try on items that users are interested in: glasses, shoes, and even furniture for homes or offices.
Medical Shift App
Created a React-based admin panel for an app created for medical workers to help manage work shifts. They could start/end the shift from the app and report incidents that happened during a shift. Also, users can create reports about a patient's sleep schedule, behavior, and money usage during the shift. The Admin panel I made was used to retrieve created reports, timesheets, and other data. The app can also sort, filter, edit, delete, or create data.
