    Software-Engineer

    Germany - Last active: 1 month ago - Tests: 6

    Software development is a personal and professional passion to me. As ex-member of the Microsoft Student Partner program I started to focus especially on Microsoft-related technologies like: - Desktop applications (WPF, Windows Forms), - Web applications (ASP WebForms, MVC4) - Mobile applications (Windows Apps, Windows Phone Apps) - Collaborative Software (MS SharePoint) I'm now working as freelancer since 2014 and offer my knowledge and performance to companies in all over the world, working as remote developer from my home office. Next to my work as programmer i am also disposed to help my clients in the following areas: - Consulting about the right choice of software architectures, - Writing of an requirements analysis, - Developer documentation, - Conception and detailed spezification of a software solution, - Project Management, - Software-Support und Maintenance. In every single project I'm seeing my personal opportunity to grow as freelancer and start my own business as software provider. Without doubts making business contacts is very important to achieve future projects from my clients. That's why a big part of my attention is dedicated to the quality assurance and testing of software.

    VoiP

    Spain - Last active: 1 month ago - Tests: 1 - Portfolio: 1

    Hi, I´m a telecom entrepreneur and active in VoiP/SIP on a global scale. Since 1996 i`m into IT and have a broad knowledge of many techniques. Because of my global understanding i do not need to know every detail to be able to provide the best solutions. Im a strong conceptual thinker, I have an extensive network of experts available (i use them myself). So if u have a problem or project, i can have that arranged for you. Me and my team do anything telecom or VoiP, we are experts in Hosted VoiP and SIP troubleshooting. But we can help u with anything u may need, including development of apps, websites and IT problem solution. We are managing three Kazoo clusters and developing whapps for them. I am very busy, but its nice to have other projects in the course of a year next to your own. They keep you sharp, takes your mind of your specific tasks and are fun, most of the time.
