You will get OTP login API with FastAPI and Redis (secure authentication backend)


Project details
I will build a simple and secure OTP authentication backend using FastAPI and Redis.
If your application needs phone or email verification, I can create APIs to generate and verify OTPs. Redis is used to store OTPs with an expiry time, so everything stays fast and automatically cleaned up.
What you’ll get:
• APIs for OTP generation and verification
• Redis storage with automatic expiry (TTL)
• Protection against multiple wrong attempts
• Proper input validation and clear responses
• Clean and easy-to-understand FastAPI code
This backend can be easily connected to your frontend or mobile app. It works well for login systems, signup verification, or any basic authentication flow.
I keep the code simple, clean, and practical, so it’s easy to maintain or extend later.

Frequently asked questions
About Mohamed
Backend Developer | FastAPI, Docker, Nginx, PostgreSQL, Redis
Trichy, India - 10:47 am local time
I enjoy working on systems that actually run in production — not just code that works locally. Most of my work involves designing clean backend architecture, handling data properly with PostgreSQL, and improving performance using Redis when needed.
I also work with Docker and Nginx to make sure applications are easy to deploy and stable in real environments.
⸻
What I usually help with
• Building REST APIs from scratch
• Designing database structure (PostgreSQL)
• Adding caching and performance improvements with Redis
• Setting up Docker-based environments
• Configuring Nginx for routing and deployment
• Integrating external APIs (payments, auth, etc.)
⸻
Types of projects I work on
• Backend systems for web and mobile apps
• Authentication systems (JWT-based)
• API backends for SaaS or internal tools
• Data-driven applications
• Improving performance of existing APIs

How I work
I prefer keeping things simple, clean, and maintainable.
I focus on writing code that is easy to extend and won’t break when your project grows.
I also try to think beyond just “making it work” — things like performance, structure, and future scalability matter a lot in backend systems.
