I've been building web apps for 15 years, since my teenage years. I've painfully realised that some of the tools and conventions we take for granted make things much more difficult than they feel they "should" be. We spend most of our time doing stuff over and over again that doesn't really feel related to each individual app (persistence, permissions, shared state). But four years ago, I found out about a new abstraction (CRDTs) and a co-discovered a new way of building apps (local-first). Ever since I've been trying to wrap up this alien new tech in a familiar, ergonomic interface.
