Perfect! Sia is your guy if you want in-depth understanding of your programming language of choice. He can dive deep and explain you the details, the whys and hows. He is knowledgeable in multiple languages (e.g. Python, C, C++). I learnt alot about good design practices in C++. He is very sharp and considerate.
