    Web Developer

    Germany - Last active: 3 months ago

    I am a web front- and backend developer comfortable in the the PHP/JavaScript/MySQL stack as well as in the RoR framework. Prior to moving to freelance web-development I worked at Panasonic Germany and have gained considerable experience working with other SQL backends besides the MySQL-server. Extensive knowledge on improving the performance of critical web-apps by optimising various aspects of database communication are a valuable tool I can bring to any web project. I am confident my skills in this area will be something, you likely will not find with many other web-developers. In general I prefer working on projects in the RoR framework but also other projects in web development that adhere to reasonable MVC or otherwise modularised design. I am more than capable of producing reusable solutions in these, that will not add to the technological debt of your project. Quality, reusability for other developers, proper documentation and (if the project scope allows) testing are standards I try not to deviate from and strongly advise potential customers to also adhere to. Despite the above goals I am able to produce results competitively fast. Failure to meet deadlines is an absolute no-go for me. I have contingency plans in place, that will allow me to deliver results no matter what. Additionally I will not over-promise on estimated time-requirements for a project. In rare cases, when starting a project from existing code, of sub-standard quality I might have to set certain limits on up-front estimates for the required time. This rule applies mostly to work outside of MVC frameworks and very large code bases and will likely not affect your project. In these cases, I will make you an offer on estimating your project needs, before moving to the actual project. Working in teams also is no problem to me. I have a strong working knowledge of GIT and SVN. I am confident though, that working with other centralised version control systems, will also not present an issue to me. No matter your project, working with me you will get results completely in line with the contract and always on time. I constantly keep my knowledge of the technology I work with up to date, so solutions delivered will not only provide good value today, but also in most frameworks be safe for a reasonable timespan.

    Tried and True Web and Mobile Developer

    Ukraine - Last active: 3 months ago - Tests: 5

    I'm a web and mobile developer based in Campbell, California. My core competencies are Ruby, Java, PHP, HTML, CSS, Objective-C , and .NET development. When you partner with me, you get a dev who believes in: Myself- I've been developing since 2007. I've worked with long list of partners from Red Bull and Scholastic to small startups building their first MVP. My Projects- I like to do things I've never done before, and if that means stepping outside my comfort zone so be it. That doesn’t mean I need to break the sound barrier with every launch. What it does mean is that I look for ways to innovate with every project. My Partners- I don’t just work with project specs and documentation--I work with people and companies. When you work with me, we become a team. That means I expect your input and ideas every step of the way. No excuses. Our Process- I'm a hard-core agilist. I believe that trial and error fuel creativity and innovation, and that those who get it right the first time aren’t working hard enough.

    Expert Android Game Developer with Unity/LibGDX experience

    Bulgaria - Last active: 11/05/2014

    All i really need to say is that I'm a game dev hackathon winner and I'm excellent in pentesting and securing code.You probably don't care for that so let me tell you what you need to know. The code i write is human readable, reusable, and expensive. Can do anything for the right price. If you don't care about code quality and only want your app out in no time, again, I'm your guy, again. Oh, only interesting ideas. No i'm not doing flappy bird clones unless you pay good money. There are plenty of developers who will get the job done. And no, I don't care how brilliant your idea is and how we can share if i do it for less money. And no, I'm not going to steal it. Nobody will. Why ? Because you are not the only one with a brilliant idea. Everybody has one. Programmers have more than you do. Don't waste my time and I won't waste yours. I'm specialized in game development so unless you are paying top bucks, don't message me. Sincerely yours, LifeOut.

    Web Application Developer and IT Security Professional

    Germany - Last active: 11/21/2014 - Tests: 3

    With 12+ years of experience, I provide strong knowledge in web application development, currently focusing on Ruby on Rails (since 2011). Beside Ruby I also have a comprehensive background in PHP and different levels of experience in other languages like Python, C, C++, Java, Objective-C or Go. If I don't fit your needs yet, I'd love to become acquainted to any interesting new technology stack. While I'm definitely not the designer kind of guy and the back-end is my castle, I also provide solid skills in front-end development (HTML, CSS) and can do server administration (Linux and UNIX especially) as well. I'm able to manage small to medium teams using agile (Scrum-like) methods with all kinds of roles, join existing teams or work on my own if that's enough for the project. With my obsession with code quality and security I'm able to offer comprehensive code reviews and audits for existing software projects to uncover flaws and weaknesses of projects you either commissioned or implemented in-house.
