About this gig
Need a custom API or want to connect different systems and services?
I develop and integrate REST APIs using Python, FastAPI, Flask and Django REST Framework, with a focus on reliability, security and clean architecture.
I can help you with:
Custom REST API development
Third party API integration
Webhook integration
Database integration
Authentication and authorization
API connections between existing platforms
AI API integration
CRM, payment, cloud and external service integrations
Data synchronization between systems
Error handling, testing and debugging
Swagger / OpenAPI documentation
Backend deployment and production ready setup
I have experience integrating APIs into AI systems, document processing platforms, CRM workflows, computer vision applications and business tools.
Every project can include source code, documentation, setup instructions, testing, revisions and post delivery support.
Send me the API documentation or describe the systems you want to connect, and I will suggest the best implementation approach.

FAQ
How many revisions are included?
I offer unlimited revisions as long as the requested changes remain within the original scope of the project. My goal is to make sure the API or integration works correctly and matches the agreed requirements.
Can you integrate third party APIs?
Yes. I can integrate external APIs, webhooks, databases, CRMs, payment systems, cloud services and AI platforms.
Can you build a custom REST API from scratch?
Yes. I can design and develop custom REST APIs using Python, FastAPI, Flask or Django REST Framework.
Do you provide API documentation and testing?
Yes. I can provide Swagger/OpenAPI documentation, endpoint testing, error handling and setup instructions.
Can you work with an existing backend or software?
Yes. I can integrate new APIs into an existing backend, application or workflow, provided the current system allows external integrations.
