    Flash Game Engine Programmer (AS3)

    United States - Last active: 21 hours ago - Tests: 4 - Portfolio: 51

    As a Flash game engine programmer, I am adept with the low-level engines for browser-based, 2D, single-player Flash games writing ActionScript 3. My own Flash games have also been sponsored, and I have coded over 50 Flash game engines for clients. Services and terms: 1). Programming and development of the game engine for single-player, 2D, browser-based Flash, non-ad game(s). This is game engine programming exclusively, and does not include designing the game(s), content management, building the web page(s) on which the game(s) might be hosted, or implementing or configuring other server-side resources (high-scoring, login system, user accounts, web scripting, databases, etc.) 2). An ideal minimum duration for the project should be at least 3 months. The project must be for the development of a new game engine, thus, not modifying an existing one, unless I was the previous, sole developer of that engine, and the engine has not been modified by someone else after I have worked on it. Furthermore, the project must not include integration onto third party social sites, such as Facebook, nor must the target platform designate mobile devices. An exception here is if I produce a Flash SWF, then send it to you (as the engine would be complete at this point), then on your end, you convert/port it to your desired platform. 3). Game design details, gameplay mechanics, media (graphics and audio) must already be provided. This includes, but not limited to concepts, gameplay rules, scoring systems, and user interface layouts/functionality. Please contact me if you have any questions.

  9. Yury Pukhalsky

    UNIX guru

    Russia - Last active: 21 hours ago - Tests: 4 - Portfolio: 1

    First thing off: I DON'T USE SKYPE nor ICQ (as they are proprietary closed protocols), but I have jabber. 20 years of experience with almost every flavour of industrial unixen, portable programming (C-99, POSIX, autotools), portable shell programming (POSIX.2) — dealt with many subtleties in different implementations. I work fast, if in doubt, ask for the estimate time. Probably it'll be cheaper than hiring someone with lower rate, but who'll spend several times more hours. I'm honest, reliable and tenacious. If I apply, that means that I'm 100% sure I can do the job meeting my high quality standards. The code must “just work”, elegant and concise. There's too much non-working, ugly and bloated stuff around:( Lifetime warranty for my work (doesn't include new features though). • Automating everything • UNIX system programming including embedded systems • Web scraping and any other text transformations/extractions. • Consulting about UNIX shell scripting (bourne shell, bash, awk, sed, [BE]RE etc). • Anyway, the list is not full, as I have experience ranging from Jenkins CI setups and maintenance to writing parsers with lex/yacc. From IP traffic handling in C++ (libnetfilter_queue plus iptables custom kernel module) to product installers. I use Gentoo and EMACS. PS. oDesk thinks my photo isn't “professional”. Therefore I have none. I'm easily googlable though, and if you want you can find any information about me outside of oDesk. PPS. Aquila non captat muscas. Normally.
