    Mario Sotil is a senior software developer with 14 years of experience. He graduated among the top 5 of his class from the Gabriel Rene Moreno University. His first work was as an intern for IBM Bolivia. At this moment he is team leader for a local company, providing solutions and support to Petrobras Bolivia for the last eight years. In addition, works as a freelance on oDesk, having at the moment a good rating. As a software applications developer, Mario is a very dedicated person with his clients and really committed to his work. On his effort to improve the process of development in Petrobras Boliva, developed a framework for Lotus Notes to facilitate the creation and maintenance of Workflow applications. This allowed to create fairly complex applications, on a really solid base, where all the typical functions are automatically processed (safety, updating, messaging, etc.) As a Freelance, he knows how to interact with costumers, understanding their needs and proposing solutions or alternatives to solve their necessities. One of the comments he got on oDesk was: “Excellent contractor! Absolutely knows what he is doing, is motivated and hardworking, cares about the work and goes the extra mile.” As the company Team Leader for the development area during the past two years, his task is the coordination between the costumer and the team, helping, in this way, to satisfy the expectations of every member that form part of the project, from both costumers and team members. Mario spends his free time practicing guitar, and playing this instrument to his two year daughter, whenever he can get hold of her.  less

    If you are looking for Android developer, especially if you need to handle multimedia data in your project, likely I will be excellent choice for you. Handling multimedia is very tough, average programmer who wasn't previously working on it will spend weeks doing some simple task like adding noise to video(know it from my own experience) while I would be able to accomplish it in hours and with highest quality. If you choose me, you will be sure that video will play on all kind of devices(had opportunity to test on a lot of them so I know which options work and which doesn't), that I will compile latest FFmpeg version for you(that's important because it progresses fast, in recent builds there are better performance and most importantly less memory leaks). Any usage of FFmpeg will not scare me, I can compile it with x264 for high-quality video, with mp3lame for exporting mp3 or any other lib you want, I can add any effects, I can work with FFmpeg through command-line by using ffmpeg4android lib or work with it through NDK. Another strong part of my skills is Parse.com . This service allows to create client-server applications without writing backend. This way you will save money on backend programmer, and will have code of better quality – situations like caching, losing Internet connection etc. is properly addressed there, much better than typically written backend. Consider hiring me if you want to develop new client-server application, or want to maintain existing Parse app. Apart from my extensive knowledge of FFmpeg+Android and Parse, I have great skills of general Android programming. As I'm always thinking about creating high-quality code, plus having knowledge of design patterns, you will end up spending less as adding new features will not turn your app into unmaintainable Big Ball of Mud. Having experience of working through NDK, managing sources through git, working with many different 3rd-party libs like Facebook API, Instagram API, Vine API, Jsoup etc. I will ensure that task will be accomplished in shortest time possible, plus I can learn new things very quick, any lib your project need - will be attached in no time. Always thinking constructively, I will propose you how to improve your app if such way exists, I will not just mindlessly do tasks you give me - as I'm thinking on overall situation, any issues will be not hidden, but presented to you and addressed if you choose to do it. I'm thinking about performance too. Users will strongly dislike if app works too slow, or drains too much battery. As a winner of regional ACM ICPC programming contest, which is focused on creating fast and memory-efficient code in short time, I have great understanding where app may actually lose speed, it won't happen, app will work great. Communication is also good part, I can adapt to nearly any time zone you want. Apart from knowing Android, I can program Flash 2D games too. I prefer to use Flashpunk framework for it, as it is very fast to create games using it. Also you may be possibly interested in C++(with Qt if needed), or Game Maker from me, can do it too. Hire me today - you will not regret.  less
