Hello. My name is Yuri, I am a radio amateur, call sign UB8JDC (ex UA9YPF), a radio circuit engineer by education. After the state destroyed the radio-electronic industry in the country, whoever did not work, mainly in the field of IT. When a year ago I was filed from my last job, where I worked for more than 10 years, due to the disastrous drop in sales due to the ban on passenger air travel due to covid hysteria, I decided to work for myself. Now I work in my specialty again and I feel great. Not all of my projects are listed below, there are still many interesting and promising ideas. An indispensable condition is prompt and high-quality technical support for hardware and software. 73!
