I'm a

I am a Computer Science student with progressive experience writing code and designing solutions. In the recent year I have taught myself how to build websites, mobile applications and design UIs from scratch. I'm very passionate about programming and the work I do, and would like the opportunity to show that.

This website is a project I undertook in my free time to practice my web development skills. It's fully responsive and uses HTML5, CSS, Javascript and Bootstrap.

Student Innovators (SINN) is the University of Cyprus student competition featuring early stage business ideas with innovation potential and/or a creative twist. Student teams are invited to present creative ideas and solutions for challenging problems with impact to the economy and/or society in a 5-minute “pitch” to a panel of judges and the audience.

Took part with one of my fellow students with our idea, Shoppy, and we made it to the finals. Shoppy is a groceries app with an innovative twist, for which we made a complete business plan and a mockup that can be found in the projects section.

This is a course by the University of Cambridge for learners whose first language is not English, but who study through the English-medium, and it develops learners' ability to understand and use English in a range of situations. Passed the exam for the IGCSE with a Grade of A.
