I was hired 6 months ago as a freelance data engineer, and after proving myself through my work quality, I am now essentially functioning as a tech lead, with full responsibility and ownership of designing, implementing, and hiring for the projects I'm assigned.

Our company is not a tech company, so I only have a couple of tech-oriented colleagues, and I barely interact with them. Now I directly report to the director of the company, who in all senses is awesome, with 40+ years of combined experience in some of the biggest oil and drilling companies globally.

However, I have some strong FOMO about not being able to learn much technical stuff from my peers or seniors. I am trying my best to learn and pick things up on my own, learning design principles, getting code reviews from chatGPT, etc. But even then, I'm afraid I am not producing the software to the highest standards of the industry since we don't have any rigorous cross-checking, and might be missing out on a lot of learning.

Can someone who has been in positions similar to these please guide me?
