    I am a freelancer with good experience and knowledge in CSS, HTML, PHP, MySQL, Python, Bash Scripting and Rest - Json APIs. I am also Cisco CCENT and CCNA certified and an avid Linux user. The platform that I enjoy using the most and build the most business solutions is Linux and occasionally Windows. I am fluent in English. I help businesses reduce operational costs with custom software solutions and and automated workflows. Desktop application development is not out of my league and one of my best projects is enjoying constant downloads every day. The project name is ControlBoard and integrates my camera control solution with the well known Wirecast streaming app to help video producers and directors save money by reducing their crews numbers. Because of the above project i gained a lot of experience with video camera control protocols and streaming technologies like dash and adaptive bit-rate http live streaming and adaptive bit-rate on demand.
