Application engineering
- Receipt processing: image upload and storage, OpenAI vision-based extraction, schema validation and a review step before data is used downstream.
- Data and permissions: relational models for organizations, memberships, receipts, reports and reimbursement workflows, with custom authentication and session handling.

- Storage: Cloudflare R2 object handling, ownership checks, signed access and environment-specific configuration.
