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.

    Dmitry Galchinsky

    C++, CUDA, Matlab, Simulink, Optics

    Russia - Last active: 1 day ago - Tests: 8

    My main skills are C, C++, Matlab, Ruby, Python, GPGPU (CUDA, OpenCL), machine learning, computer vision (incl. OpenCV), DSP (audio processing, image processing, less video processing). I work with these technologies for several years and can show projects in which I used them. My additional skills are are: JavaScript (simple HTML5, Web Audio API), Haskell, C#, SQL, Qt... I used these technologies to solve minor tasks, not large projects as for the "main skills". Batteries included: unix shell scripting, vcs (hg, git), ssh, makefiles, cmake. I'm looking for long-term (more than 1 month) remote projects in R&D and prototyping (the fields are machine learning, computer vision, audio processing, image processing). Small $200 projects will be probably declined as "not interesting" because I prefer to dig into the project without having to switch the clients often. The projects I most proud of: * The development of several algorithms for a company that develops satellite orientation devices. The details are below at "Employment History" * I developed the interactive mode for Clay programming language (claylabs.com/clay/) that uses LLVM JIT technique. My motivation was to understand how the open source community works but I post it here as a proof that I'm sufficient enough at C++ to improve a compiler. * UpWork clients gave me opportunities to help them in different fields: image stitching, video stabilization, GPGPU financial application, semi-automatic tumor detector, Shazam-like application and dozens of small projects listed at my UpWork profile.

    JavaScript/React/Angular/D3/CSS3/HTML5 Frontend Developer and Designer

    Russia - Last active: 2 days ago - Tests: 9 - Portfolio: 11

    Currently I am focused in creating rich client-side apps using JavaScript advanced techniques, CSS3 and HTML5 features. I am keen in creating perfectly looking user interfaces and visualizations with help of D3,js and my great experience with UI/UX. Using best practices and a streamlined workflow I manage to work on complex solutions that include hundreds of user-cases and apps views that are often created as real-time dynamic apps. I use TDD where applicable in my frontend engineering work. Being a problem solver for my clients I am sure that clean, semantic markup and content-driven, responsive layouts are the way forward. I believe in building sites that are device-agnostic, adapting layouts and experiences to a user's viewing environment. I am a fan of progressive enhancement in my work. Having solid backend development experience with multiple languages like Python, C# and JavaScript I try to imagine and see the whole picture of projects I work on.
