About the channel
Per Aspera ad Astra is a channel about IT, modern technology, and practical learning. Here I share free courses, educational videos, occasional discussions, news about technologies shaping the future — with a strong focus on AI, but not limited to it. This channel grows together with its audience and is for anyone interested in technology, no matter how much experience you already have. I share what I learn, what I build, and what I test along the way. I’m always learning too, and this channel is a place where we can keep learning from each other and grow together over time.
