An Online Sports League Management System

I used Laravel 5.4 to create a league management system catering to a number of sports. It enabled the user to create leagues, matches, reports on performances, post results, and automatically generate team and result pages.

I architected the entire solution and created the entire back end and front end using Laravel, MySQL, and Vue.

DataCentral: Advertisement Costs and Revenue Management System

I created this platform in Laravel to monitor the costs and revenues of advertisements for campaigns and landing pages. This included calculating the confidence for landing pages effectiveness, generating reports of profit (daily, weekly, monthly, and annually), and fetching data (cost, revenue, visits, impressions) from various APIs.

Review Management System

I created this internal software in Laravel 5.3 for a company that needed a place where they could list their products and campaigns and a public interface for people to sign up for samples. This also involved creating blacklists for users that didn't follow guidelines, reports for campaigns and users, and various user roles.
In 2010, when I was working at my job, I came up with an idea about creating a web app localized to a region that would let people ask and answer questions that are common problems in the area. I worked on this from conception to implementation while also building a community and letting it self-moderate.

RockMe | Online Coaching App

This is an online coaching app for global mobility professionals and expats. It is one of a kind and is still under closed alpha development.
