Build Data Migration Utility: Zoho Creator to Supabase

Project goal: Create a utility to migrate flat table data and PDFs from Zoho Creator to a Supabase database, ensuring data integrity and efficiency.

Scope of work:
- Evaluate old tables (zoho) versus new (supabase) schema we have built, and advise on changes to new schema structure to help capture data model for our fitness app we are moving.
- Build a utility (typescript / javascript and node.js) to migrate data that will:
1. Authenticate to Zoho via REST API.
2. Extract a few hundred rows of text data from ~ 6-10 tables plus associated PDFs for each client we track in Zoho Creator app (a few thousand clients total).
3. Transform extracted text data to match the normalized schema in Supabase (e.g., splitting fields, remapping values).
4. Insert transformed client records into Supabase database.
5. Store associated PDFs in storage on Supabase for each organization, with metadata in supabase
6. Identify to-be-migrated data as it accumulates in zoho, and provide mechanism for triggering new update

Additional information
- Timeframe for project should be under a week.. this is just for an internal tool.
- This is for a multi-tenant HIPAA compliant app that is in mid-development now, to create real data in back end.
- The right developer is welcome to support additional projects or come on as a full time hire for that supabase/nextjs project.
