We are building VYXN.AI — a full AI content generation platform with a web application, Templates, Workflow / Space, dynamic credits/coins pricing, AI provider integrations, Telegram bot and Telegram Mini App.

The final goal is not a small prototype. The product should be built in clear stages:

1. Technical Foundation

- User dashboard

- Admin panel

- AI provider integration layer

- Basic working version of Workflow / Space with node-based UI

- Telegram bot

Responsibilities:

- Review the full project brief and propose a practical implementation plan

- Build or lead the core web application

- Fixed milestones preferred for the first stages

- Code must be developed in our GitHub repository

- Deployment should be done through project-owned accounts

- Long-term cooperation possible if the first stage goes well

We are not looking for a large agency. We prefer a strong individual developer or a compact team that can move fast, communicate clearly and build a practical commercial product in stages.
