I will build and fix rest API integrations with python and fastapi
Junes

About this gig
Need to connect two systems, fix a broken integration, or build a reliable API backend?
I build and troubleshoot API integrations using Python, FastAPI, Flask and Django.
I can help with:
- REST API integration and development
- Webhooks and event-driven workflows
- OAuth2, API keys and token authentication
- CRM, SaaS and third-party integrations
- Database integration and data mapping
- Scheduled API jobs and data synchronization
- Pagination, rate limits, retries and error handling
- Debugging failed or incomplete integrations
- Custom middleware and API wrappers
- Backend services and production deployment
- Device, IoT and vendor APIs where documentation/access is available
I have worked with both standard SaaS APIs and unusual vendor/device integrations, so I am comfortable with imperfect documentation and edge cases.
My goal is not just one successful API response. I build integrations that handle authentication, failures, real-world data and ongoing operation.
For complex or multi-system projects, please message me before ordering so I can confirm scope and recommend the right package.

FAQ
Can you integrate any API?
I can work with most documented REST APIs and many less conventional systems. Send me the API documentation or platform name first and I can confirm what is technically possible.
Can you fix an API integration someone else built?
Yes. I regularly troubleshoot authentication, malformed requests, webhooks, data mapping, rate limits, errors and broken backend logic. Please provide the relevant code and error details.
Which technologies do you use?
My primary stack is Python with FastAPI, Flask or Django. I also work with REST APIs, webhooks, OAuth, SQL and NoSQL databases, Docker and cloud services when required.
Can you integrate APIs that require OAuth2?
Yes. I can implement OAuth2 flows, API keys, bearer tokens and other common authentication methods, including token refresh and secure credential handling.
Can you work with device or IoT APIs?
Yes. I have experience with vendor, smart-device and hardware-related APIs as well as standard SaaS platforms. Send me the documentation and access requirements so I can review feasibility.
Can you deploy the API or integration?
Yes. Deployment can be included depending on the package or added separately. I can help configure the backend, environment variables, database and runtime environment.
Should I contact you before ordering?
For Standard, Premium or unusual APIs, yes. Send me the systems involved and desired outcome and I can confirm scope. Small, clearly defined Basic tasks can usually be ordered directly.
