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.

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.

We're Codexa Soft, a backend team building APIs with Django, Django REST Framework, and FastAPI for SaaS products and startups. We design production backends in Python that stay fast and stable as your users, data, and integrations grow.

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. We build systems that scale with growth, so you're not rewriting everything six months after launch.

Recent work shows what that looks like. We built a production backend for a SaaS platform handling real users and AI-driven workflows, and shipped a mobile app backend with Stripe payments and in-app purchases that went live on schedule. Across projects, 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 usually bring us in to design and build a Django, DRF, or FastAPI backend from scratch, to take over an existing codebase that's grown messy, to integrate services like Stripe and external APIs, or to tune PostgreSQL and Redis so things stay fast under load.

We work in Django, Django REST Framework, FastAPI, Flask, PostgreSQL, 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, send us a short note about what you're working on, and we'll tell you honestly how we'd approach it.
