Sergey Kukunin

Ruby on Rails fullstack developer


Kiev, Ukraine


I'm experienced full-stack senior web developer, for whom computer science is passion and primary hobby. Frontend and backend engineer. Problem solver, the more complex is problem, the more I would love to solve it. While having deep experience of Ruby and PHP based stack of technologies, I'm open for other aspects of computer science: algorithms, micro-controllers, system and application programming. Great knowledge of patterns, and ability to build flexible and scalable architecture. Much time I worked as free-lancer, as well as coordinated work in team in office made me organized, responsible, motivated and disciplined. Good server administrative skills: Linux and Windows servers; ... moreAWS infrastructure; web-servers, mail servers, DNS; auto-deployment, continuous integration.

    Just some background, I'm a longtime buyer on oDesk. I'm very familiar with the process, so my reviews mean a lot more than your avg odesk buyer. To me, most of the developers on oDesk, promise the world, and deliver poor goods. Because PHP among other languages are pretty much a commodity right now, it's hard to sift through the shit (try finding a quality graphic designer on oDesk, it's impossible). One of the main problems on oDesk is that developers want to get things done as soon as possible without doing it right the first time because most buyers don't give a proper Scope, QA, and/or know what they're doing. This results in a lot of back and forth and wasted time. Sergey took the time to figure out the scope and understand the reason for what I was doing so he could write better code. What that means is not a lot of back and forth, constant communication, and I think in the first time in oDesk history, something done right the first time. I will use Sergey over and over again and hope he will do as good of a job for me next time as he did this time.
