Ioana S.

Front-End Developer, Web Designer / Graphic Artist

Romania - Tests: 3 - Portfolio: 29

Hello :) A little about me...Since I was 4 years I started painting on papers, then on walls, and I didn't stop, I went on cars, motorcycles with the air brush gun and on statues too so as you will see the art for me is a lifestyle. In the year 2009 I started working in Photoshop and I simply found a path for my ideas to have shapes and colors. My portfolio reveals that from 2009 until now I've went from graphics to webdesign and I always keep in mind and follow the latest trends on the market. As a developer, I started to enjoy the coding part and I wanted to be really good, as I am today in my humble opinion in: HTML, HTML5, CSS, CSS3, JQUERY, MEDIA QUERIES (from 200px-1024px), WORDPRESS, PHOTOSHOP, GIMP. The most important quality that I have is an unstoppable ambition. I am communicative, dynamic, inventive, love working in a team, I have the ability to make decisions under stress with a smile on my face. I hope you enjoyed my little monologue and perhaps we can turn it into a real conversation. I really am looking forward to that. Best wishes!

Alex S.

Software Engineer

Ukraine - Tests: 3 - Portfolio: 2

I've got my first computer when I was 7 years old. One week later first program was ready. Programming languages and processors have changed but I can't stop till today. I help people transform ideas into websites and applications. I try to understand how things work, only after I build a solution that picks up business to the next level. I can guide client over the bridge between business process and IT, providing consulting on all steps from choosing technology to deployment and maintenance. My biggest passions in my work are algorithms and distributed systems. I believe that fundamental theory in computer science is a basis for significant achievements. It's important that every new day brings new knowledge. Based on my experience in software development, work approach boils down to the following rules: - do something only if you have all required information - if you don't have required information - ask questions - if you don't know how to do - you should know how long can it take to learn
