Nobel Radio Contest

Nobel Radio needed a web application for a photo contest. The application's main function was to enable people to upload a picture of their bedroom while allowing others to vote for those pictures, count up all the votes, and finally declare a winner.

The application was developed using PHP (CodeIgniter) for the back end and JavaScript for the front end for a better user experience.

MBHS School Management System

MBHS, a local school in my area, had a school management system already in use, but it lacked some important functionality; the portal was built using Laravel and Vue.

I contributed to the development of the portal, adding the functionality needed by both the school administrators and the teachers and also extending the functionality already available in the application.

Jive Inventory System

Jive created a product, a school management portal, and they needed a way to track the school installs, revenue, number of students using it, and other data.

The Jive Inventory System application was created using Laravel and Vue; it enabled investors, employees, and Jive admins to monitor how well their product was doing. It included access control, so the data was obscured based on user hierarchy.

eCommerce Comparison App

A Laravel-based application intended to compare electronic products from different online vendors based on user preferences.

I was the full-stack developer on this project. I scrapped data from three eCommerce websites using Goutte and manipulated their data to be displayed according to the users' preferences. I made the application easily extensible by storing the scraper configuration for each website in a JSON file.
