Dear client,
Thank you for this job posting! First of all, we need to understand that your son should be treated and taught a little bit differently than adult people. Therefore, before reading further, I would like to let you know you are very welcome to have a chat with me or to reach out to me in order to make sure I am the right person for mentoring/teaching your son.
Talking about Lua and coding in general, I have experience in lots of languages and the concept is pretty same everywhere, including Roblox Lua. For sure, I am not pretending to be an expert in Roblox Lua but I could look through what I used to know and read the topic your son likes especially.
Just to make a note, I was also a kid who was so curious to learn but I wish nobody could help me that time.
Anyway, looking forward to working with you!
Best regards,
Anton Danylov
