Maciej Zubala Agency Contractor

Senior Ruby On Rails developer

Poland - Tests: 4 - Portfolio: 6

Software development is not only my profession but also my greatest passion and hobby. This is why I spend majority of my free time improving my programming skills, learning new concepts, technologies, languages and tools. I get the greatest satisfaction when products I develop are released to the world and people start using it - that makes me want to spend more time at work. When not in front of my monitor, I'm probably taking care of my daughter or doing some sports (tennis and swimming most of the time).

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.

United States - Tests: 6 - Portfolio: 12

Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.
