    I have a live PostgreSQL database that is ready to receive a backlog of customer details. All the fields are already defined; what’s missing is the accurate, consistent data itself. I will export small batches of raw information (CSV / Excel extracts, PDF scans, or screenshots) and your task is to key those records directly into the tables I specify. What I need from you • Clean, verify, and standardise each customer record before insertion. • Use SQL or a tool such as pgAdmin to enter the data—whatever keeps the audit trail clear. • Respect existing constraints (unique email, foreign-key relations, etc.) so we avoid duplicate or orphaned rows. • Provide me with a short progress report after each batch—rows inserted, errors found, and how you ...

    I want to remove the manual steps from my current data-export routine. The goal is a hands-off workflow that: • pulls fresh data from my primary system on a schedule or event trigger • maps every field to a custom column schema I provide • delivers a perfectly formatted CSV to downstream apps or storage so my CRM, ERP and marketing tools can pick it up instantly You’re free to build this in Python, Node, SQL scripts, Zapier, Make (Integromat), n8n, or another integration platform—as long as it runs reliably, is easy for me to tweak later, and can handle future schema changes.
