Vale construir sua versão de Bubble?

Build me the app I currently run on Bubble, as plain code I own. Requirements:

- First ask me for: the 3-5 core screens, the data types with their fields,
  and the single workflow that matters most. Rebuild that app, not Bubble.
- Stack: Node + Express + better-sqlite3, server-rendered EJS templates plus
  htmx for interactivity. No SPA framework, no build step.
- CRUD for each data type: list page with search and filters, detail page,
  create and edit forms with validation.
- Workflows become plain functions: a form submit updates rows, sends email
  via Resend (key in .env), redirects. Scheduled workflows become node-cron
  jobs in the same process.
- Auth only if people other than me log in: email+password sessions with
  bcrypt and a session cookie, no roles unless I named them. If it is just
  me, skip auth and bind to localhost.
- File uploads go to uploads/, images resized with sharp.
- One SQLite file plus a nightly CSV dump of every table, data never trapped.
- Out of scope: a visual editor, a plugin system, anything platform-shaped.
  The deliverable is one app that deploys with node server.js on a $5 VPS.
- README: deploy steps and how to add a field later, the code is the editor
  now.
