Junior Developer to CTO

Hey everyone,

Hope this message finds you well. Was wondering if I could get some advice?

I was recently approached by 2 startup founders looking for a CTO. A little bit about myself, dropped out of college, attended a coding bootcamp, started working as a full time full stack developer in Nov. 2022. Been working at the same company since then, however I feel as if I'm getting too comfortable/not growing & need a new mountain to climb.

Definitely don't have the expertise/experience for the CTO role, however I understand that growth comes as a result from uncomfortable times and am definitely up for that challenge! My current tech stack consists of: SQL, Java, C#, ReactJS, Angular (also experience w/ Azure Data Factory). As SWE's with years of more experience than me, what are the most essential tools I should be adding to my arsenal? AWS? Security best practices? System architecture?

Thank you for taking the time to read this post, immensely appreciated my friend.

Cheers,
Matt
