18 months into building, want to start sharing about the journey. How to start?

I'm a newer founder (been working at my B2B app about 18 months). Self-taught data eng (~5 years in that), originally mechanical engineer. Taught myself to code javascript over the past 12 months, definitely leveraging Cursor to help build.

Originally built my product on Retool (low-code / no-code) while learning coding basics and building out ETL infrastructure. Fully rebuilt a React / Node.js app and relaunched about 6 months ago.

We're B2B in the ecom/DTC space. Just crossed $250k in ARR, just me and a part-time college dev (who i'm hoping to hire full time in the spring when he graduates).

I'm struggling with how/where to start on posting about what I'm building. LinkedIn? X, TikTok, here? Open to any thoughts and feedback on what has worked for you.

Happy to share more about the project if helpful. Thanks in advance!
