Towards own product. From custom development to own platform

I'm a developer ASP.NET. I have a small development team. In this article, I will touch on some of the problems of custom development and how we solve these problems, and how we gradually moved to creating our own product-a web platform with an approach where SQL is at the top of the list. https://falconspace.site/blog/na-puti-k-svoemu-produktu--ot-zakaznoy-razrabotki-k-sozdaniyu-svoey-platformy Looking for developer feedback on this approach! I would appreciate your criticism and comments!
