Hi, my name is Sebastian Volland, I'm a freelance software developer from Cologne, Germany with over 10 years experience developing applications for web, desktop and mobile. I provide:
I provide iOS app development for iPhone, iPod touch and iPad. I use Apple's integrated development environment XCode and the programming languages Objective C and C++ to build apps. I'm familiar with Apple's guidelines and review process and I can help you realize your app idea and bring it to the App Store. One of my great passions is game development. My game development framework of choice for 2D games is Cocos2d. Beside iOS development I also provide Mac application development.
I have over 10 years experience in web development.
Before I decided to become self-employed, I worked over 8 years in
the IT industry as a Senior Software Engineer where I maintainted
large web applications.
My programming language of choice for web based projects is
on the backend. I provide clean HTML5 and CSS and I know how to
transform a designer's PSD file to appropriate (CMS-) templates.
interactive web sites, HTML5 games and server-side
I'm not afraid to handle low-level in-depth tasks like developing
apache modules in C or hacking and recompile nginx.
I have the required skills to set up and maintain web servers,
recompile the Linux kernel if needed, write bash shell scripts, set
up cron jobs etc. Linux is my operating system of choice for server
based tasks (mainly Ubuntu, Debian).
I love the commandline. If I have the choice, I prefer to work on
a project by logging into remote server with SSH and program in
my favorite text editor
Here are some of my own projects or projects I contributed to.
Sebastian is the perfect combination of professionalism and experience. He is an excellent programmer and almost more importantly, I trust he will get the job done as quickly and efficiently as possible. He is straight forward and honest, and makes sure the project gets done right. Job type: iPhone Game Development with PHP backend
