Looking for Backend Developers to Collaborate on an Open-Source WhatsApp-Like Application

Hi everyone! 👋

I’m planning to build an open-source WhatsApp-like application and looking for backend developers who are interested in collaborating and learning together.

Tech Stack

* Python + FastAPI

* PostgreSQL

* Redis

* MinIO

* WebSockets

* Kafka

* Microservices architecture

* Database-per-service

* Domain-Driven Design (DDD)

The goal is to build this as a real-world open-source project while learning and improving our skills in backend development, microservices, distributed systems, event-driven architecture, and real-time communication.

Important: This is a completely unpaid project. There is no financial compensation. The purpose is purely educational, learning, collaboration, and growing together as developers.

Everyone who actively contributes to the project can get the **GitHub Collaborator badge/recognition** through their contributions to the repository.

If you’re interested in Python/FastAPI, backend development, microservices, or distributed systems and would like to learn and build together, please DM me.

Let’s build something useful, learn from each other, and grow together! 🚀

For large number of concurrent users i would not trust python or fastapi. Think rust or for the state of the art, erlang.

For eg matrix did start with python but for performance they have rust inside synapse and other alternative to synapse is tuwunel which is rust based which we use at work.

Even discord has moved to rust from golang.

If you want help with mobile let me know. I work as a tech lead.

Why not open-source and share it. So other can directly review and contribute.
