FAQ
Do you only work with Flask or can you build with FastAPI and Django too?
I work with all major Python backend frameworks including Flask, FastAPI, and Django. Depending on your project needs, I will suggest the best framework. For lightweight REST APIs, Flask or FastAPI works best. For larger web applications, Django is a great choice.
Can you connect the Python backend with a React frontend?
Yes, I specialize in building Python REST APIs that connect seamlessly with React JS frontends. Whether you need a simple data fetch or a fully integrated full stack web application, I can handle both the backend and frontend connection end to end.
How long does it take to build a Python backend or REST API?
It depends on the complexity of the project. A simple Flask or FastAPI REST API with basic endpoints can be delivered in 2 to 3 days. A complete Python backend with database, authentication, and React frontend typically takes 7 to 14 days.
