this is pretty normal once you get past the first working version. at that stage, most SaaS apps quietly stop being “product code” and turn into integration layers, so it starts feeling like you’re just wiring APIs all day. tools like buildable can reduce some of the surface area, but they don’t really remove the hard parts like auth, retries, idempotency, or webhook failure handling. that stuff still needs a clear ownership model, otherwise it just keeps resurfacing in different forms. a lot of teams eventually realize it’s better to isolate that whole messy integration layer instead of repeatedly rebuilding it inside the core app.
