From the prototype that proved it to the product that ships
If you already built something in Bubble, Softr, Glide, or a stack of Airtable views, that is a working spec and we treat it as one. The rebuild keeps the flows your users already understand and replaces the parts that break: authentication, permissions, payment handling, a database schema that will not fall over once the table gets long. You keep the idea. The plumbing underneath it changes.
