Experience

Admin Dashboard for an Electric Scooter eCommerce App

Developed a full-stack application using Next.js on the front end and a REST API built with Node.js with Koa on the back end. I was the sole developer assigned to get the app to the finishing line. My goal was to finish the rest of the admin dashboard interface, extend the REST API to cover all the required functionalities and sync Shopify data with the MongoDB database using webhooks.

Webinar App for Hosting and Participating

A full-stack application developed using React and a Socket.IO server built with Node.js. I was one of the front-end developers who worked closely with the rest of the front-end team as well as the back-end team to implement a functional interface with a real-time chat, build a fully-featured rich text editor, and display custom Adobe Illustrator animations using Lottie.

Admin Dashboard for Solar Panels Analytics

A full-stack application developed using React and a server built with PHP and Laravel. I was the front-end developer who worked closely with the back-end developer to implement a functional interface that includes tables with filtering and pagination, charts, and CRUD operations.
