Is your API failing, webhook not triggering, or backend integration giving you errors? I can help you identify the problem, fix the issue, and get your application working reliably.

I'm a full-stack developer experienced in Python, FastAPI, Node.js, REST APIs, Firebase, and backend integrations. I help startups, businesses, and development teams troubleshoot technical issues without unnecessary complexity.

API debugging: Fix failed requests, incorrect responses, HTTP errors, and authentication issues.

Webhook troubleshooting: Resolve webhook delivery failures, payload validation problems, and event-handling issues.

Third-party integrations: Connect your application to external APIs and business services.

Backend bug fixes: Investigate Python, FastAPI, Node.js, and related backend errors.

Payment integration troubleshooting: Debug payment API requests, callbacks, and webhook verification.

Data and authentication issues: Troubleshoot JSON payloads, API keys, tokens, and request headers.

Investigation of the agreed issue.

A focused fix within the agreed scope.

Testing of the affected functionality.

A clear summary of the changes made.

Guidance on any remaining issues or recommended next steps.

Share the problem: Explain what is failing and provide relevant error messages.

Diagnosis: I'll review the relevant code and identify the likely cause.

Implementation: I'll apply the agreed fix.

Testing and handover: I'll verify the affected functionality and explain the changes.

Please share your technology stack, a brief description of the issue, relevant error logs, and your expected outcome. Never send passwords, private keys, secret tokens, or production credentials through chat.

I focus on clear communication, practical solutions, and fixes that address the underlying problem.
