You will get a scalable FastAPI backend with PostgreSQL
Project details
You will get a production-ready REST API backend built with FastAPI and PostgreSQL — fast, secure, and built to scale.
With 6+ years of full-stack development experience, I specialize in building clean backend systems that are easy to maintain and extend. I take database schema design seriously — proper normalization, efficient indexing, and structures that grow with your application without costly rewrites.
Every API I deliver comes with auto-generated Swagger documentation, JWT-based authentication, async database operations for high performance, and clean code that your team can actually read and understand.
I don't just write code and disappear — I communicate clearly throughout the project, ask the right questions before starting, and make sure the final delivery matches exactly what you needed.

About Sonu
Full-Stack Developer | FastAPI, React, Flutter | 6+ Years Experience

What I bring to your project:
I specialize in the Python ecosystem — FastAPI, Django, and Flask — for building fast, secure backend systems, paired with React and Tailwind CSS for clean, responsive frontends. I also have hands-on experience with Laravel (PHP) for projects that require it.
For mobile, I build cross-platform apps using Flutter for both Android and iOS — single codebase, native performance, faster delivery for clients who need apps on both platforms without doubling the budget.
Database design is one of my core strengths. I work confidently with PostgreSQL, MySQL, and MongoDB, and I take schema design seriously — proper normalization, efficient relationships, indexing, and structures that scale cleanly as your application grows. A well-designed schema saves you from costly rewrites later, and that's where I focus extra attention.
On the deployment side, I regularly set up and manage production environments on AWS EC2, Ubuntu VPS, DigitalOcean, and Heroku, including Nginx configuration, SSL setup, S3 storage integration, and CI/CD basics. This means I can take your project from local development to a live, stable server — and your mobile app from code to app store — without needing a separate DevOps person.
Recent work includes:
A multi-tenant SaaS platform (FastAPI + PostgreSQL with schema-per-tenant architecture, Redis caching, and a Flutter mobile app for staff)
A full e-commerce platform with Next.js storefront, React admin panel, and FastAPI backend, deployed on a production VPS with Nginx and PM2
I'm detail-oriented, communicate clearly in English, and treat every project like it's my own product — clean architecture, proper documentation, and on-time delivery.
Let's discuss your project requirements — I'm happy to share relevant code samples or do a quick technical call before you commit.
Steps for completing your project
After purchasing the project, send requirements so Sonu can start the project.
Delivery time starts when Sonu receives requirements from you.
Sonu works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement Analysis & Schema Design
I review your requirements, ask clarifying questions, and design the database schema and API structure before writing a single line of code.
Backend Development
I build all API endpoints, authentication, business logic, and database integration using FastAPI and PostgreSQL with clean, documented code.
