Roberto Garrido

Roberto Garrido Agency Contractor

Senior Mobile & Desktop Developer

Spain - Tests: 2 - Portfolio: 12

I am a Senior Mobile and Desktop Developer looking for new challenges everyday. My main interests are focused on 2D/3D and mobile videogame programming, and apps. Since I was in college, I always chose those projects and subjects related with mobile, videogame, and 3D graphics. I've always been an enthusiastic about graphics, and programming is not only my job, but also my hobby. I can divide my career into two main periods, first as researcher, then as professional programmer. I started working as an intern in a Research Center, where I developed my research and programming skills and participated in various projects, both as programmer and also as project manager, all of them related with mobile Virtual and Augmented Reality. I even published 3 articles in the field of 3D Computer Graphics, and attended various conventions. After my period as a researcher, I move to the professional industry where I work two years as main graphics programmer in a Simulation Company. There, I develop my team work ability, working everyday with colleagues of different professional skills, like 2D/3D designers. My main goal was to get a highly stable and flexible C/C++ based rendering engine, able to be used in multiple kinds of simulators, like trains, tranvs, and bus. My last full time collaboration in a company was now 3 years ago, in a medical imaging company. As part of the development team, I learn new APIs and frameworks related with the medical imaging world. My main contributions were on the 3D visualization module, where a doctor (specialized on aorta prothesis) could interact with a 3D representation of the aorta and determine the exact size of the prothesis to be implanted. The last 3 years of my career have been focused on my freelance programmer career. Here in upwork, I'm one of the top rated profiles, with more than 2,200 hours billed on my back. I sell programming services to both individual clients and startups, specifically in projects involving 3D programming, app programming, and videogames.

Barry Deas

UX / UI Designer for the web and mobile

United States - Tests: 5 - Portfolio: 9

http://www.bazdeas.com I'm a UX / UI designer with a serious hankering for creating handsome interfaces—be it web or mobile. I believe in absolute focus, which means that I put all my energy into designing. I don't code. I do know how to code, but I prefer not to because I don't get the kind of joy and thrill from it that I do from designing. I prefer to let a dedicated coder handle that. Also, I only work on one project at a time, so that I can put all my energy and passion into it.

Sergei Basharov

Sergei Basharov

Senior JavaScript Developer with Great Eye for Details and Design

Russia - Tests: 9 - Portfolio: 5

As a practicing consultant and developer, I put substantial thought as into organizing the whole project, so into structuring the code in the specific parts of the app. The stage of setting a project basement is as important, as the development process following it, putting the team on a healthy productive path. As a result, the project earns its fat-free shape, allowing team members to focus on their tasks, not on working around conceptual inconsistencies or fighting with resurrecting issues. When it comes to actual development, I choose to write compact, isolated code. Ubiquitous well-written tests are what makes me sleep like a rock, my clients feel in good hands and safe. That’s why I put tests at the top of my priority list. The role of tests becomes crucial in the world of JavaScript. The language with its long curved path of evolution, is far from being free of quirks. Some are just unobvious and others are totally bizarre. To keep the grade of monkey business low and productivity high, I follow the best practices, use patterns where appropriate, learn new techniques and demand myself and other team members deliver quality code which conforms to the high industry standards.
