In my years in college, I have personally work on different languages like: Angular.js, Python, RoR(Ruby on Rails), C#, Java, node.js but I have mastered PHP.
Although, I don't have any experience on using codeIgniter or any other PHP framework but I am knowledgeable about OOP and the MVC Framework.
I am very productive and organized. Since, I focused most of my time on working on the back-end side. I also sometimes gave my teammates with opinions on the UI/UX design for our projects. We made the experience of the user excellent as possible and made the interface simple even first-time users will comprehend.
I have alot of knowledge with using HTML5, CSS3, Javascript and Bootstrap 3.x and 2.x framework.
