    Software Developer C#/F#/Javascript & SQL Server DBA

    United States - Last active: 22 days ago - Tests: 2 - Portfolio: 2

    Over the past 10 years I've developed software both professionally, and as a hobby. I enjoy working on more than just my daily grind, so I've come here for a little something extra. Do you have an interesting project? Read on, I may have the skills you need. Let's talk desktop/back-end development: C#, Ruby, Go, C, Objective-C, Powerbuilder, SQL (ANSI/MSSQL), Perl. Those aren't languages I've just spent a few hours on; I've shipped products or currently maintain projects in those languages. How about web development? I love writing responsive, cross-browser/cross-platform sites that work as well on the desktop as they do on your phone or tablet. It's a great challenge to stay ahead of the curve.

    Expert iOS Consultant & Developer

    Russia - Last active: 19 hours ago - Tests: 6 - Portfolio: 4

    I'm a certified programmer and system architect with 7 years of experience under my belt. My job is to ease my client's life by making a polished and profitable iOS app. I can: • develop an effective, reliable and easy-to-support native iOS app from scratch; • fix, update, or complete your existing Objective-C / Swift / C++ code; • integrate various APIs and SDKs like Parse, Pushwoosh, RevMob, Xplode, Flurry, etc; • implement advanced web interaction models, like custom data synchronization. Having an advanced scientific background, I can work with physical, graphical and probabilistic models, both with engines and without them. So complex animations and simulations are not a problem! But the greatest feature you'll get is targeting your goals, not just a technical task. You don't have to speak developers' language. Just state your problem, and we'll find the balance between the turnaround time, the development cost, and the project value. Let's make your new app a success together!

After injuries continued to sideline his competitive sports career he returned home and became one of the trail blazing pioneers to complete a newly offered and nationally acclaimed entrepreneurship degree program offered at Mount Royal. During his studies Branden also re-found his love of technology, ingrained in him from childhood, where his father would lug a “Luggable” computer up and down flights of stairs so that Branden could learn the artful skills of programming when growing bored of the unbeatable tic-tac-toe games. Just months after graduation quit a stable job with a fortune 500, to begin building his mobile advertising empire. Within another 4 months, before the days of social media and online viral campaigns was featured in over 30 traditional media outlets including CBC, CNN, and the Globe&Mail. Using technology unseen in the industry, as an accelerator Branden took lead of the new and emerging market space. Several years later, after negotiating international licensing agreements, Branden closed one final deal and ventured onwards to new entrepreneurial experiences. Branden co-founded Tradeopolis Communications in 2006, and grew this organization into a profitable consulting firm with increased profits year over year. Branden believes that to survive in business requires obsessive focus and relentless determination, coupled with genuine and honest interactions with all those around him. He marries these together in perfect harmony. Nominated for the 2013 Guardian Small Business Leader Of The Year, Branden is passionate about connecting and building relationships, specifically with entrepreneurs and works in an advisory capacity with various clients he believes have the "it" factor.
