    Senior Ruby On Rails developer

    Poland - Last active: 19 hours ago - Tests: 4 - Portfolio: 6

    Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).

    Hi, glad to see you here! I'm a Team Lead and Fullstack Senior Ruby Developer. I'm specializing on high-level application architecture design, prototyping and writing solid testable code. I'm prizewinner into 2 Upwork coding challenges (oDesk's Coding Challenge and Upwork Code It Up). When I have time I contribute to opensource projects. GitHub - akolomiychuk. I'm Team Lead and Lead Developer in SmartDev. We're a fullstack developers who focus on Ruby on Rails and Yii. Besides that I'm good at establishing development workflows in existing teams - ask me for the case study! One of projects: I and my team created custom CMS and online ticketing platform for Australian company SEMIPERMANENT. Project launched in 2012. At 24 July 2014 it had 5613 sold tickets on events for designers on 3 continents and we continue improving it. I want to make products for real people. So I do not work with projects in which I'm not believe. I put my soul into every project, so it's important to me. The same way I'm not working with projects where the deadline is yesterday. I believe that deadline - it's when someone seriously messed up. I'm - about calm and confident way to move towards the goal. I'm Ukrainian, who live in Siberia - the center of Russian outsourcing. If you see anything how I can help you - feel free to drop me a line! Take care!
