    Senior iOS developer

    Belarus - Last active: 2 days ago - Tests: 15 - Portfolio: 15

    Software developer for more than ten years. Started my first iOS application back when iOS SDK was introduced. Since then I had explored plenty of dark corners of iOS ecosystem and this really helps me to pick the right tool for the job. I am self-motivated agile worker. Always friendly and proactive in communications which makes me a good team member/leader. I have extended experience with following technologies: Apple native frameworks - from UIKit/Autiolayout and CoreData down to OpenGL, CoreAudio and Accelerate.framework Ad-Hoc app distribution - Testflight, HockeyApp, ; In-House app distribution Project management - JIRA, RedMine Continious integration - TeamCity, Jenkins My code contains best practices, always clean, self-documented, editable, localized and synchronized. Most of UI is in storyboard. I can use any VCS, but git is my favourite one. My experience is not limited by C / Objective-C / Objective-C++ / Swift. I have experience in backend development so it is not secret "where it all comes from" or how to report a bug. oDesk officially recognises me as one of the best mobile developers for the projects I have worked on, my work history and communication skills.

    Petr B.

    Senior Developer, PM

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 1

    I have strong background in UNIX/Linux software development, Master's Degree in Computer Science. I worked on Enterprise high-load distributed hosting automation systems as a Team Leader (3.5 years in SWsoft, Inc., now called Parallels). For the last 6 years I'm running my own small software development business in Russia with primary focus on Python/Django apps. Not pure Web but often involving integration with hardware (Proximity Cards, Sensor Screens) or external systems like Payment Processing, SMS Gateways, GABRIEL (Airline Reservation System), etc. I can take an idea and turn it into a working business, through all the intermediate stages. Also I have experience of investing my own funds in my projects, so I feel the difference between "perfect code" in a month and "good enough" code that increases the revenue right now. Nevertheless, my code is very good: no copy-paste, always written with performance, flexibility and security in mind, etc. On oDesk I'm looking for (and actually find :) interesting projects with a sight on long-term fruitful cooperation. I'm also open to smaller activities (e.g., consulting) where my knowledge can be helpful.

    Mobile Apps -- Web Development

    United States - Last active: 1 day 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.
