    Software Engineer

    Ukraine - Last active: 25 days ago - 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
