PostgreSQLWe 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
2. First usable product release
3. Full commercial launch scope

- 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

- Comfortable with fixed milestones and clear acceptance criteria
Nice to have:

- React Flow or node-based workflow UI experience
- AWS / GCP / Cloudflare / S3-compatible storage
- Telegram Bot / Telegram Mini App experience

- Remote
- Contract or full-time possible
- 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.
