Full-Stack JavaScript Developer

Poland - Last active: 10 days ago - Tests: 9

I am seeking opportunities to build robust, well tested front-end solutions that require a lot of JavaScript. Here's a short list of bigger projects I have worked on over the last few years: - ING Developing a single page banking application in Backbone/Marionette. We're also using jasmine, karma, nodejs, express.js, gulp, requirejs, d3.js, jquery and many more. I'm a technical team leader of one of the Scrum teams, responsible for the transfer's section of the app. - William Hill William Hill is one of the largest bookmakers in the United Kingdom. I have developed a wide range of websites that required a lot of front-end scripting. I had a chance to work on a truly scalable solutions as the websites were in 24 languague versions. - AQA AQA is one of five Awarding Bodies which are recognised by the regulators of the public exams systems for England, Wales and Northern Ireland. I had the privilege of working in the AQA office in Guildford directly with the kind and professional AQA team who had a really positive attitude about the project. My work focused mainly on the implementation of a cut-up, which involved converting an HTML and CSS template into the proper syntax for the CMS, provided by a third-party company whilst reporting to the Project Manager for AQA's project.

Back-end and front-end dev and photographer

Ukraine - Last active: 2 days 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.

Mobile Apps -- Web Development

United States - Last active: 30 days ago - Tests: 8 - Portfolio: 12

I have a BA (with honors) from the University of Iowa (also double majored in Linguistics). I also have a Web Development Professional Certificate from Minneapolis Community and Technical College. I have been developing apps for the iOS platform since 2009. I have also worked on native Android apps, and I have worked on and created several cross-platform hybrid apps using Apache Cordova (or Phonegap) as well as custom hybrid solutions. I am resourceful and self-motivated when finding applicable solutions to programming problems (it's like a fun puzzle...). In the past I always focused on Apple platforms and was an expert on the now antiquated Macintosh Toolbox of the 1990's. I used C/C++ on these old generation Macs and on UNIX boxes while studying computer science (we also used early Java on the workstations). I still have a sweet spot for native objective-c development on iOS. Recent projects have included custom Cordova / Phonegap plugins, applications which make use of bluetooth iBeacons (as well as Gimbal BLE beacons), and in the last year I have worked extensively with Location Services including GPS functionality and Geofences. In the early days of iOS development I worked a lot with audio processing and muti-touch interactions. I never really set out with the intent to become a project manager, but I communicate well and it seems my role in many gigs recently tends to creep in that direction.

BI Developer and some other nice things

Poland - Last active: 1 month ago - Tests: 4

I started my career as C++ developer, then I moved to Visual Basic and SQL, but when things are getting serious you start to use a real database, so I learn PL/SQL and from there I moved to Data Warehousing and Business Intelligence. Moving abroad was only the next natural step in my search for more interesting and challenging projects. I admit it, a girlfriend was a good reason too. I think I passed the test, if I still have no intention to come back to mamma. When I joined MicroStrategy I knew only that I enjoyed my time with the rudimentary BI tool I was using, I knew something more was out there. With my Oracle and programming background I started working on ETL and Data Modelling projects, but you don't do BI if you don't understand your customer's business. Finally a way to combine my job and my communication degree. In the last four year I have be travelling around the world working in different environments and having my part of fun doing it, and I was lucky enough to do it adding new experiences and skills to my curriculum. And a wife as well. And now? now I'm looking for the next step in my life.
