One failing Python API or webhook flow, repaired and handed back within 48 hours after funding, scope confirmation, and receipt of sanitized test inputs.

Included: • Reproduce one defined defect • Implement the smallest practical fix • Add or update the relevant validation and error handling • Verify three agreed test cases • Provide run commands and a concise handoff note • One revision limited to the agreed defect

Safe working rules: • The fixed-price Contra project must be funded before implementation or access • Synthetic or sanitized payloads only • Never send passwords, API keys, production credentials, or real customer data in chat • One bounded flow; broader integrations require a separate scope

Not included: • Full application rewrites, infrastructure migrations, UI redesigns, open-ended support, or third-party fees • Guaranteed business, security, compliance, or exactly-once outcomes

Relevant public proof is independent Python/API demonstration work, not a claimed client engagement. I use transparent AI assistance for research, testing, and implementation, and remain responsible for the agreed deliverable.
