personal project mentorship?

Hello reditors,

I am a dev mgrating from web2 to web3. Few months ago I started digging and now I am working on a personal project for which I would like some advice on. I already have a mere MVP built. Did that as a part of learning.

I believe the end goal of the product has a potential to take off. (Yes I naive world view, I understand).
Here I ask for recommnedations on ways to get mentorship so that I can improve my codebase and get a taste of real world coding in web3 world. Finding vulnerabilities, optimising gas and what not. I have tried doing these myself but have been doing it from the comfort of myself.

Do you think hackathons are a good way of moving forward? Or should I search of accelerators? Just anything you can recommend or would like to mention.
