Ask HN: Not Growing as a Technical Cofounder of a CRUD App

I'm a technical cofounder and a solo developer of a CRUD app. At this point, all technical challenges has been solved. I will not learn cloud any time soon cause we're using PaaS, and we're focusing on building instead of scaling. I'm still finishing my degree for the next 2 years, so there's no option for me to work and learn in a bigger company. Sometimes, I'm spending money to ask senior programmers that I know to consult about building a maintainable software. I feel that I'm not growing as a software developer. What should I do?
