    Backend programmer with NFC experience

    Russia - Last active: 4 months ago - Tests: 1 - Portfolio: 1

    Hi, I've been working in IT since 2003. I have worked mostly as a backend programmer and system architect for several e-commerce and mobile commerce startups that are well known in Russia and the post-Soviet space: * http://money.yandex.ru/ * http://mobi-money.ru/ * http://money.beeline.ru For these projects I have used PHP, C, Java, MySQL, Linux, Memcached, regular expressions, XSLT, SOAP and many other things. Three years ago I moved into the NFC world and since then I've been developing innovative payment and ticketing NFC services for a start-up company. One service is already in use and allows passengers of Moscow's "AeroExpress" trains to use their PayPass/PayWave bank cards: http://www.aeroexpress.ru/ru/press_releases/news20081285.html I developed a distributed system that includes: * Multithreaded servers for each train station that manages dozens of NFC readers and turnstiles and processes transactions in pseudo-realtime mode with delayed transaction authentication. * A central server that provides back office interface for tech support and accountants, collects logs and other information from station servers, and distributes black and white lists of cards across all stations connected to the system. Sometime ago I made a few minor commits to an opensource LibNFC library that made it possible to use it to communicate between a NFC reader and Mifare-enabled USIM cards and dual interface contactless smart cards with mifare functionality. I started to use Ruby as a main programming language in 2008. I should note that my Ruby experience is quite different from a great majority of ruby programmers; I use Ruby not only for Rails but also for communicating with different types of hardware using binary TCP-based protocols or serial ports. Rails are used mostly for creating backoffices (ActiveAdmin) and API web-services.

    Web developer

    Russia - Last active: 4 hours ago - 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, Blockchain.info 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 Blockchain.info 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.
