Short story: I started working with PHP as freelancer in 2008 while studying in local College in Computer Science. Got in love with Unix operating systems back there. First Unix OS was FreeBSD. Even now I can remember bunch of formatted HDDs (by mistake of course) and working FreeBSD on my machine, without any idea why I installed it and what to do next with it. Tried out linux after that. Switched few distributives since then (Ubuntu, Fedora, Gentoo, Arch Linux, OpenSUSE). After finishing college I went working to the small outsourcing company as PHP developer and to the local University as Computer Science student (2009). After 1 year working with PHP I decided to try out new programming language for better productivity and more coding comfort. Tried out few popular in web languages (C#, Java, Ruby, Python). In love with Ruby since then. Was working as freelancer in few small and medium size teams for almost 4 years. In 2012 got interested in Clojure, brought all available books about Clojure on the market, learned it, still mastering it. Got interested in functional programming, learned Haskell on basic level. I'm still working/hacking with Clojure as language of the choice. Love ideas of functional programming, think that FP is much easier to understand and reason about than currently popular imperative object-oriented programming techniques. Always was excited about AI and Neural Networks. Took machine learning course on coursera by Andrew Ng. Leaned touch typing to become faster in vim, switched from QWERTY layout to Programmer Dvorak just as experiment few years ago, and now I don't want to go back to QWERTY, Dvorak is much more comfortable. Huge fan of the virtualization and cloud technologies. Dreamer with hope to make the difference and create something valuable.  less

    I provide Web Architecture definition, Web Development and Consulting services to the early stage startups, entrepreneurs seeking a reilable tech person to create an MVP to validate their business ideas and established businesses looking for someone to help with ongoing tasks and further development of their products. This includes: - working out customer requirements - database design - application development - API design and implementation - MVP UI prototyping with Twitter Bootsrap, Zurb Foundation (or any other CSS framework), jQuery, etc - 3rd party API integration (Stripe, Twitter, Facebook, etc) - Amazon web services (EC2, S3, SQS, SES) integration - app level statistics gathering for further analysis - web server configuration - load balancing and caching setup - database server configuration - security hardening - deployment automation - server level monitoring - bottleneck identification and elimination - long running or heavy load tasks decoupling into background jobs - cloud hosting advisory (if needed, experienced with Rackspace, Amazon Cloud, DigitalOcean, Heroku) - SaaS/PaaS provider advisory (hosted databases, mail handling, etc) How this works: Transparency, agile process, short iterations & communications are essential keys to the project success. If you don't have already established process we can schedule daily/weekly skype sessions to discuss what was done & plan for the next week, plan iterations by creating & arranging task cards in Trello or Pivotal Tracker so you will be able to follow the project & measure progress. Drop me a line If u need any of the abovementioned or similar tasks to be completed. I am a generalist, so chances I already know/can quickly catch up with required technologies are high. Yuri  less

    I'm a Ruby on Rails developer, with previous experience in C, Python, SQL and other programming languages. I have also used jQuery and jQuery UI extensively, and am fairly experienced with those libraries. I began working in Ruby and Ruby on Rails over a year ago, and found it to be a perfect match for me. I mostly use HAML as a markup language, but I have used ERB and Slim as well. Of course, I am also very familiar with CSS and HTML. I'm a huge proponent of open source software and I use Linux and Vim as my choice of OS and text editor. I use Git as my main choice of version control software. I'm fairly young and a fast learner. I have worked in groups a lot, related and unrelated to software development, which makes me flexible and easy to adapt to most environments. My Github repository: https://github.com/mivanek  less

    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.  less
