Full-Stack Chat Developer Needed

We are looking for an experienced full-stack developer to build a complete chat system for our existing platform.

Our current stack:

* React Native (Frontend)
* Node.js (Backend)
* MySQL (Database)
* Cloudflare

This project is NOT limited to frontend development. The selected developer will be responsible for the complete implementation of the chat system, including frontend, backend, database design, APIs, real-time messaging, architecture, optimization, and deployment support.

IMPORTANT:

The main thing we want to see is a REAL chat system you have personally built.

When submitting your proposal, please ONLY include:

1. A chat product/system you personally developed.
2. Screenshots, videos, live demos, or app store links.
3. Your exact role in the project.

Please do NOT send generic company profiles, AI-generated proposals, or unrelated portfolio items.

We are specifically looking for someone who has successfully built and deployed a production chat system before and can own this project as a full-stack developer.

Candidates who can demonstrate real chat products they have built will be strongly preferred.
((((We don't care what features your chat system includes. We simply want to see a real chat product that you personally built and that we can review live. If we like what you've built, we may ask you to create something similar for our platform.)))) Show More
