    I am the founder of The-DIY-Life, an R&D company in the Field of Internet of Things. I am a Leader of a professional developers Team, working on the field of IoT and Embedded Systems. Our Company has several "modules on shelf" to reuse on our projects. we care more about the quality of the project we work on than the quantity of the projects. so we invest time on documentation and version control system using Git. We use freelancer.com as a business platform to know more clients, and feature our work. Despite we support the opensource software, and we have several opensource work on our page on Github, we also respect the privacy of our clients work. less
