I will investigate and fix one clearly defined bug in a Python backend or automation service.
Good fits include:
• a FastAPI endpoint that returns the wrong status or data;
• a failing webhook or REST API integration;
• JSON parsing or validation errors;
• retry, timeout, or rate-limit handling;
• a database query or state-management bug;
• a Docker startup or environment-configuration issue;
• a deterministic Telegram bot backend error.
You will receive:
1. A short written explanation of the cause.
2. The focused code fix.
3. A regression test or exact verification script.
4. Setup and handover notes.
5. One written clarification round after delivery.
All discussion, questions, updates, and delivery happen in LaborX chat. No call is required.
Fixed package: $40. Delivery: 1 day after the issue is reproduced. Scope: one bug, one service, and up to 1,000 relevant lines of code.
This package does not cover a full application rewrite, credential recovery, CAPTCHA bypassing, account automation that violates platform rules, or systems requiring real-money trading. Work starts after the contract is funded through LaborX escrow and the issue, expected result, and acceptance check are agreed in writing.
