About this gig

I will build a clean, secure, and scalable backend using Python and FastAPI.

I can develop REST APIs, CRUD systems, authentication, database integrations, business logic, and third-party API integrations for web and mobile applications.

Services include:

FastAPI REST API development

PostgreSQL / SQLite integration

JWT authentication and role-based access

CRUD endpoints and business logic

Third-party API integrations

SQLAlchemy and database migrations

Docker setup

Error handling and validation

OpenAPI / Swagger documentation

Clean, maintainable source code

I have 5+ years of software engineering experience working with production backend systems, APIs, databases, microservices, Docker, and Kubernetes.

Please message me before ordering if your project has complex requirements so we can define the best architecture, scope, and package.
