I experienced Python, Laravel, React.js, and its' frameworks for over 5 years and I worked on many projects such as eCommerce apps, telehealth services, webinars, Rental & Booking systems, mobility services, and etc. In especially the favorite skills of mine are WebRTC and video/audio streaming skills, and I had done in my duty for the features such as video/audio streaming, video conferencing, and video/audio chatting in the above projects. So I had got deep knowledge about technologies such as RTMP, RTSP/RTP, HLS, SRT, WebRTC, and many platforms and media servers such as Wowza, Kurento, Jitsi, Asterisk, Mediasoup.
