Back-end and front-end dev and photographer

Ukraine - Last active: 1 day ago - Tests: 2 - Portfolio: 1

I specialize on Ruby on Rails and front-end development. In spite of the fact I have got a degree in International Journalism and Translation, I worked as QA and IT Sales for total of 3 years (from 2008) and then moved to web development from Jan, 2012. I have performed both back-end tasks (from basic CRUD to making simple APIs or server scripts) and front-end (building static websites from scratch or developing views with twitter-bootstrap). I believe the experience is formed with the quality of the projects, you have delivered, and not with the years of sitting in front of the laptop. Specialties: ruby 1.9.2+, Ruby on Rails 3.0+, linux and MacOS X environment, unix-shell, Git, SQL (SQLite, MySQL, PostrgeSQL), HTML, Haml, CSS, Sass, Less, twitter-bootstrap, javascript, jQuery Here is link to my github profile: https://github.com/amseledka I do photographs and various design tasks in my spare time, as well as help my friends with Russian-Ukrainian-English translations.

Linux sysadmin, cloud deployments specialist

Czech Republic - Last active: 20 hours ago - Tests: 9 - Portfolio: 1

I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.

I am passionate about solving problems by writing robust software applications for the iOS platform. As an engineer I believe in clean code, written by following best practices. As a private contractor I value professionalism and integrity. Over the past years, I have been working with a wide range of frameworks including Apple's Core Data, Map Kit, Social, Event Kit, Message UI, Accounts, Address Book, Core Graphics, UIKit and 3rd party libraries such as AFNetworking, Parse SDK, StackMob SDK and many more. I really enjoy working with technologies such as Core Data, in a client-server architecture. I also have experience with the Ruby programming language, the Rails framework and the Sinatra DSL, where I can deliver full stack RESTful interfaces for your projects. I am seeking opportunities to build apps for the iPhone and the iPad from the ground up or to improve an existing project.
