Backend dev
Freelance mostly, usually it was usual and not that usual API development, business logic layers, etc. To select the most interesting ones: 
microservices-based web scraping, with standalone modules "by request"; 
scaffolding elasticsearch and configuring logstash to read syslog logs remotely;
avoiding "http long polling" in socket.io and implementation of WebSockets from scratch, well almost from scratch :)
Вмію але дуже не люблю front end.
Маю здоровий глузд у 2022.
