Project details
Professional FastAPI Development: High-Performance & Scalable APIs
Need a production-grade backend built for speed? I specialize in high-performance REST APIs using FastAPI. Whether for a Flutter app, an AI service, or enterprise systems, I deliver clean, asynchronous code designed for reliability.
Why Choose This Project?
I provide a complete architecture focused on long-term maintainability:
Async Speed: Using async/await to handle high concurrent traffic with minimal latency.
Pro Security: Implementation of JWT tokens, password hashing, and secure CORS configurations.
Modular Code: Strict adherence to PEP 8 standards and modular structures for easy scaling.
Auto-Docs: Every API includes interactive Swagger (OpenAPI) documentation and Pydantic validation.
DevOps Ready: Fully Dockerized setups ready for AWS, DigitalOcean, or Heroku deployment.
I bring a "Security-First" mindset to every project. Let’s build a robust API that scales with your business.

Python or PHP developer with API and AWS Lambda - MUST WORK EST WORK HOURS!
Terrible communication, you don't know when he is working or when he is not working. I'm pretty sure I was overcharged and didn't catch it in-time. Didn't stick to the specifications as he only built a database and I had to tell him to go back and actually create the api connection, poor code definitely wouldn't hire for anything.

Steps for completing your project
After purchasing the project, send requirements so Raj can start the project.
Delivery time starts when Raj receives requirements from you.
Raj works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Analysis & API Design
We'll define the API architecture, endpoints, and data models based on your needs. I'll create a technical roadmap to ensure all business logic is mapped out before coding begins.
Environment Setup & Core Development
I'll set up the FastAPI environment with Docker and the database (PostgreSQL/MySQL). Then, I'll code the core logic, Pydantic schemas, and integrate security features like JWT authentication.
