Web developer

Russia - Tests: 12 - Portfolio: 12

Lately my work is about integrating Bitcoin-related functionality in websites or developing special purpose apps, like a bitcoin trading bot or a websocket chat. It involved various technologies: node.js, websockets, Ruby, Sinatra framework, API, PayPal API. During the years of my work prior to this I've performed a big variety of tasks in developing and reworking websites. This involved a lot of programming with PHP+MySQL, layout works with HTML+CSS, Javascript (with and without jQuery), AJAX. I had experience working with various CMSs: OpenCart, Joomla!, Wordpress, MODx Revolution, DataLife Engine, SimplaCMS, self-written websites. Also with different frameworks: MODx, Yii, also self-written MVC structures. I also use regular expressions (RegExp) fluently and have quite some experience with that. I've integrated a number of payment systems in several websites, which included PayPal, Bitcoin (native and via API) and russian WebMoney, Yandex.Money, QIWI, Robokassa. All payment processors utilize mainly same principles, so it's no problem to learn and integrate something new quickly. My work included creation of web grabbers and parsers that process information from external websites, for example to fill up an online store database. Also setting up and administrating Linux/FreeBSD VPS servers: installation and configuration of Apache, PHP, MySQL, Python and some other uncommon software. Aside from pure web, I've developed Python and Ruby scripts for various services. A part of that was developing Bitcoin-related services, including API communication with bitcoind daemon, automated receiving/sending Bitcoin payments, trading on BTC exchanges via their API, and other stuff. I'm looking for interesting work opportunities that would let me develop my skills and acquire new ones. Cryptocurrencies are especially interesting to me, but if it's not the case, no problem. Most likely I can be useful to solve your programming issues, so feel free to contact me.

Ukraine - 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: I do photographs and various design tasks in my spare time, as well as help my friends with Russian-Ukrainian-English translations.
