The way you describe your experience resonates with me. I've been wanting to start my own side business for a while, but haven't been able to think of a product. I think it's impressive that you were able to come up with an idea and get it out there into the world. Some of the lessons you mentioned are ones I've learned while competing in DEV challenges and hackathons. The lessons on first impressions and tool selection are so, so important. Keep up the good work!
