Project details
You will get a clean, tested integration between your application and the third-party API you need — LLM APIs (OpenAI-compatible), payment gateways, logistics/OMS platforms, or any REST API.
I'm a backend developer working in Go and Python, and API integration is what I do in practice: I've built systems that call LLM APIs for automated grading and RAG document search, and pipelines that move data asynchronously with message queues.
What sets my work apart:
• Production habits, not demo code — retries, timeouts, error handling, and logging are included, not afterthoughts
• Scope first, code second — I confirm endpoints and data flow with you before writing a line
• Complete handover — source code, setup instructions, and a short doc so you can extend it later
Pick Starter for a single straightforward API, Standard for a production-hardened integration, or Advanced for multi-API work or a scheduled data-sync pipeline.
Not sure which tier fits? Message me with your API docs link and I'll tell you before you buy.

About Zhongmou
Backend Developer | Go, Python, API Integrations
Chongqing, China - 4:47 am local time
What I can do for you:
• REST API design and backend development (Go/Gin, Python/FastAPI)
• Third-party API integration (LLM APIs, payment/logistics APIs, data sync pipelines)
• Automation pipelines and monitoring tools (scheduled data ingestion, rule-based filtering, LLM-based classification, alert notifications)
• AI-powered features: chatbots, document processing, OCR + translation workflows
• Desktop utilities for Windows (screen capture, OCR, overlay tools)
Recent work: an AI companion chat app, a document/data monitoring pipeline (Go + SQLite + LLM scoring), and a real-time screen translation overlay tool. I write clean, config-driven, well-tested code and communicate progress daily.
Hourly rate is flexible for small, well-scoped tasks — message me with your requirements and I'll reply with a concrete plan and estimate within a few hours.
Steps for completing your project
After purchasing the project, send requirements so Zhongmou can start the project.
Delivery time starts when Zhongmou receives requirements from you.
Zhongmou works on your project following the steps below.
Revisions may occur after the delivery date.
Review the API docs and confirm scope
I read the API documentation, confirm the endpoints and data flow with you, and lock the scope before writing any code.
Build the integration
I develop the integration in Go or Python with clean, commented code that follows your codebase conventions.
