Experience
Data Science and AI Explorations
https://github.com/mishedone/mo-ml-and-data-scienceA GitHub repository where I publish my Data science and AI explorations (or at least the ones I am allowed to). Some of them are the result of an eight-month course I took in 2018 on data science and machine learning.
Contains projects on various topics like a Perlin noise implementation and a craft, homemade and in-store beer comparison.

Mo-lottery Project
https://github.com/mishedone/mo-lotteryThe Mo-lottery project is a pet project of mine created in my spare time. It aims at implementing various statistical algorithms to analyze past lottery draws and tries to predict the numbers in the next draw.
It consists of two sub-projects. The first one is a back-end read-only API written in pure PHP that provides endpoints for retrieving supported lottery games information like numbers, draw size, past draws, and so on. The second sub-project is a single-page application built with Backbone.js and Bootstrap that implements the analysis and prediction algorithms and provides a user interface for browsing supported games information, auditing algorithm results, and checking the latest best score predictions.

Third Place in the JavaScript Classes Innovation Award
In February 2014, I won a great prize while competing for the Innovation Award of the JavaScript Classes website. My entry was a pet project of mine, a JavaScript-enhanced gallery that enlarges thumbnails on hover instead of on-click.
Dett Online Store
https://dett.co/en/I helped my girlfriend's sister create her own online store using Prestashop. I was responsible for installing, configuring, and maintaining the website in my spare time. I've also created a few custom modules and did some theme modifications so the website has all the necessary functionality.
