    Petr B.

    Senior Developer, PM

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 2

    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.

    Geoff Hackworth

    Experienced iPhone/iPad/Watch Software Engineer (Native Apps)

    United Kingdom - Last active: 13 days ago - Tests: 17 - Portfolio: 15

    I am a highly-skilled software engineer and computer science graduate with 23 years of professional experience. Software development is my greatest skill and I have an incredible attention to detail and perseverance in getting the job done, and done well. I've been developing native Objective-C iOS apps for over 3 years. I don't use tools like PhoneGap or Appcelerator. I have direct experience with Apple's policies, device capabilities and account management procedures from publishing my own apps (see my portfolio for screenshots and iTunes links). By hiring me you would benefit from my extensive skills and experience. Technologies change, but first-class analysis, design, development, testing and debugging skills can only be built from many years of hard work and real-life development experience. I work from home in a distraction-free environment using a Mac with dual 23" monitors. For good test coverage I own several iOS devices: iPhone 4S, iPhone 5, iPhone 5s, 1st generation iPad, 3rd generation iPad, retina iPad mini, iPad Air 2 and 42mm Apple Watch. I don't believe you can get the true "feel" of an app by just using the simulator. For client testing, I can use TestFlight to deliver builds throughout the project. Thanks for taking the time to read my profile. I'm looking forward to working with high-quality product designers and creating some great apps together.

    Senior iOS developer

    Belarus - Last active: 10 days ago - Tests: 15 - Portfolio: 8

    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 a 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.
