I need a straightforward system whose sole focus is the clean, reliable management of our financial-transaction records. The core task is to design and build an admin interface—web-based is fine—that lets me add, edit, search, and archive transaction data quickly without touching the underlying database directly. Data integrity and easy retrieval come first; advanced analytics or complex reporting can wait for future phases. Key pieces I expect: • A well-structured database schema optimised for high-volume financial transactions. • A secure, role-based admin dashboard with full CRUD controls and quick filters (date range, amount, client, etc.). • Import/export in CSV and XLSX so I can move data between this system and our accounting tools. • Basic validation rules to prevent duplicate or malformed entries and an audit trail that tracks every change. Tech stack is flexible—Laravel, Django, Node, or similar are all acceptable as long as the code is clean and documented, the UI is responsive, and deployment can be handled on a typical Linux server. Acceptance criteria 1. I can create, read, update, and delete a transaction within three clicks. 2. A test dataset of 50,000 rows uploads in under two minutes and can be queried instantly. 3. User roles (admin, editor, viewer) behave exactly as defined in the permissions table. 4. Full source code, migration scripts, and a concise setup guide are delivered on hand-off.
