Building a "full back-end learning path" is antithetical to the good advice to build something small and simple first - to build an "MVP".
In a way, we have been building mini-MVP's - each course on Boot.dev is a product on its own, but we think what makes the whole product powerful is the "career path" that we've been building towards.
Anyhow, we just launched our "Learn SQL" course, and this one has really "completed" the whole back-end path for us, adding a ton of value for a relatively small amount of work. Most of the new courses up to this point have been great - it's more content that adds value for students. This one is different, it rounds out the entire offering!
We're really excited, we had to build new infrastructure to get it working. Because of that, it took about 2x the work that the other courses did to write, but we think it will provide about 4x the value that any other individual course did.
Let me know if you have questions about the decisions we made to get to this point!
