You will get a scalable REST API backend built with Django, DRF, or FastAPI
Top Rated
Project details
We build production-grade REST API backends with Django, Django REST Framework, and FastAPI for SaaS products and startups. Most early-stage products don't fail because of a weak idea. They fail because the backend was built like a prototype and buckles the moment real users arrive. That's what we fix.
You get clean, documented REST endpoints, a PostgreSQL database designed for performance, secure authentication, and integrations like Stripe where you need them. Everything ships Dockerized and deploy-ready, with tests on the critical paths so the system stays stable as it grows.
Recently, we shipped a mobile app backend with Stripe payments and in-app purchases on schedule, and delivered a production SaaS backend running automated, AI-driven workflows.
What sets us apart is that we build for production, not for a demo. We write maintainable code that your team can pick up later, and can either build a new backend from scratch or take over and clean up an existing one.
If you're building a SaaS product or worried your backend won't scale, send a short message about what you need, and we'll tell you honestly how we'd approach it.

Scalable Node.js Backend Development for PCI DSS Compliance Assessment Platform
Codexa Soft team did an excellent job developing the scalable Node.js backend for our PCI DSS compliance assessment platform. He demonstrated strong expertise in Node.js, NestJS, and the MERN stack, delivered high-quality work, and remained solution-oriented and accountable throughout the project. Communication was clear, deadlines were respected, and the final result met our expectations. I would gladly recommend him for backend development projects.

Beway Mobile App Development
We had an excellent experience working with the Codexa Soft team. They delivered high-quality backend development that was scalable, reliable, and built with strong attention to detail. The team handled complex requirements efficiently and remained responsive throughout the project. Beyond backend work, they also provided solid support with Stripe integration, in-app purchases, mobile app development, and web application development. Communication was clear, deadlines were consistently met, and the overall execution exceeded expectations. I highly recommend Codexa Soft to anyone looking for a skilled, dependable, and professional development partner.

Travel Planner App with Interactive Map and Navigation
Working with this team was honestly a great experience. From the start, communication was easy and clear, and we always felt that our project was in good hands. They really listened to what we needed and were not afraid to suggest better or simpler solutions when it made sense.
They handled everything we asked for, including maps, payment system integrations, and other technical parts, without any problems. Deadlines were met, everything worked as expected, and the whole process felt smooth and well-organized.
Overall, we were very happy with the cooperation and would not hesitate to work with them again or recommend them to others.

Most early-stage products don't fail because of a weak idea. They fail because the backend was built like a prototype and buckles the moment real users arrive. That's the problem we solve, in Python or JavaScript/TypeScript.
Recent work spans both ecosystems: a scalable Node.js/NestJS backend for a PCI DSS compliance assessment platform, a production Django/FastAPI backend for a SaaS platform handling AI-driven workflows, and a mobile app backend (MERN stack) with Stripe payments and in-app purchases. We've handled the parts that usually break first: payment flows, third-party integrations, slow queries, and databases that were never designed to scale.
Clients bring us in to build a backend from scratch in Django, FastAPI, Express, or NestJS, to take over a messy existing codebase, to integrate Stripe or other APIs, or to tune PostgreSQL, MongoDB, and Redis for performance.
We work in Django, Django REST Framework, FastAPI, Flask, Node.js, Express, NestJS, PostgreSQL, MongoDB, Redis, Celery, WebSockets, Docker, and AWS.
If you're building a SaaS product or sitting on a backend that won't hold up as you grow, Python or Node.js, send us a short note about what you're working on, and we'll tell you honestly how we'd approach it.
