    Senior developer, Project Manager

    China - Last active: 4 days ago - Tests: 9

    Professional and hobbyist developer, with over 15 years of actual development under the belt and 6 years in 'hands-on' management positions (as engagement manager in a consulting firm and then as a CTO in a web startup). My technical experience ranges from desktop (C/C++/C#/Java/VB, scripting in Python/Ruby/VBA), embedded (PIC, ATMEGA, ARM), web (PHP, Ruby on Rails, JS/Coffeescript, HTML5 and some understanding of web design principles and UX construction) and ERP/Business Intelligence (SAP BW, QlickView). These days (2014), I am mostly doing web dev (front-end/back-end) in Ruby, Python and CoffeeScript - they allow very quick iterations and cutting through tons of boilerplate to get to a MVP as quickly as possible. My skills in C/C++ are a bit rusty, but I'll gladly dust them off for an interesting project :) I read Java and C# and don't mind using them as external dependencies, but I do not enjoy working with those. As for my management experience, I have been leading small and large engagements (up to 2 millions EUR) in offshore settings (India, China), both on-site and remotely I feel like I have a good understanding of the communication and management challenges involved in freelancing. As your contractor, I see myself adding value by challenging your requirements, helping you define clear specifications and, if the assignment is large enough to need more than myself as a developer, I can help you screen out other offshore resources and simplify your outsourcing experience.

    Android developer with ffmpeg and parse.com skills

    Ukraine - Last active: 2 months ago - Tests: 12 - Portfolio: 7

    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 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.
