Aleksander Ponomarev Agency Contractor

Lead Ruby and Javascript developer

Russia - Tests: 7

I am full-stack Ruby and Javascript developer from Russia with 10 years of expirience in web dev. I enjoy working on Rails and React apps — architecture design, coding, testing and maintaining. I am a professional remote worker and oDesk is my full-time job. That means I don't work on spare time, I do that when I'm most productive. As a developer I love to participate in and launch long-term projects and create production-quality web apps with well-thought architecture, thorough test coverage and clean, readable code. Here's why you should work with me: 1) Communication & presence Despite the fact that I'm probably in a different timezone than you (UTC+4), presence and communication will never be a problem. * I have fluent written and spoken English, lived in US, travel a lot, I even have IELTS certificate! * I work every work day at the office space , so you can expect daily commits and 100% availability * I have reliable internet connection, backups and a conference room for confidential online meetings * My typical work hours are between 9am and 6pm Moscow time, but I can be available as early as 5PM (yeah, I like mornings), which allows me to work effortlessly with clients form Australia and US, as well as Europe. * I am online at Skype, I read my emails and reply promptly, and I even have a mobile phone that you can call or send message to * Sometimes I even work during the weekend, but this is a rare case, nobody wants to get burned out. 2) Professional skills * I create web apps, APIs, integrate and migrate legacy systems. I have built apps with multitencany and multiple database adapters, offline, real-time and many more. * I am a TDD adept. I work with RSpec and Mocha/Chai, but I can adapt to your environment. * I can pessimistically estimate time required for specific feature, and tell you beforehand if it becomes obvious that estimation was wrong. * I stick to deadlines, commit daily and write comments. * I refactor wisely, my code is DRY, readable and clean * Rails development for 5 years, since 2.2. That means I can maintain, improve and migrate legacy projects, as well as create new ones with Rails 4. * Serious Javascript development for 5 years. I've worked with plain JS, prototype, then jQuery, then Backbone/Marionette, then Node and Coffeescript took over, and finally React/Flux is dominating client-side development (just my point of view). * General web development for 15 years. We all do HTML5/CSS3 now, but you never forget things like Dreamweaver and Perl/CGI. 3) Projects Unfortunately I can't show you screenshots or even links to the apps because of NDAs, but write me an email and I'll send you some code samples Some of the big projects I've been working for recently: * Australian company, worked on airport security apps and created big app for real estate * US client, created data warehouse that integrated lots of sources and presented analytical data in different ways (powered by D3.js) * US client, Backbone/Phonegap mobile app for real estate agents. * Cisco Russia, 4 years as lead web developer, created number of intranet projects, marketing apps and many more

Maksymilian A.

HTML5, CSS3, JavaScript, jQuery, Ruby, Sinatra developer.

Poland - Tests: 2

I believe that the Internet evolves at the rapid pace, technologies and methods of web development are different each month but only little group of certain web makers understand that fact and this effects in division of them into two groups: those who stick with writing code in old and deprecated way and those who use fresh yet production ready technologies and don't fear to play with experimental ones whilst maintaining high quality of the code. I proudly announce that I belong to the latter group, because I love innovation and self-improvement. In real life, high quality products and services are what I prefer thus offering the poor quality work would make me feel extremely bad. I've spent several years watching the Internet from the other side on my personal websites, now I decided to freelance to improve the Internet. As a beginner at oDesk, I decided to charge little less than usual ( Hourly rate below is a median one, the exact rate will be given during the consultations about the product ). Please do not hesitate to contact me about anything, I am certain that we will make some great business together.
