Telegram Digital Marketplace Bot

I need a Telegram bot that lets users buy and sell digital software and apps straight from their chat window. The core focus is a smooth marketplace flow—no escrow or rating system for now—so development can stay lean and launch-ready quickly.

Here’s what I’m looking for:
• Product listing flow: sellers send a command, upload their software file/key, set price, description, and an optional screenshot.
• Catalog browsing: buyers can explore active listings with pagination and keyword search.
• Secure checkout: integrate an in-bot payment gateway (Telegram Payments, Stripe, or crypto via Bot API) and return a unique download link or license key once payment clears.
• Order tracking: each transaction is logged, and both buyer and seller can check order status or resend the download link.
• Admin console: simple commands for me to view sales stats, manually approve or remove listings, refund a payment, or ban a user.

Tech expectations:
– Use the official Telegram Bot API.
– Code in Python or Node.js—whichever you’re fastest with.
– Store data in a lightweight DB (PostgreSQL or MongoDB).
– Deploy to a VPS or Heroku-style platform; hand over setup scripts and environment docs.

Deliverables:
1. Fully commented source code in Git.
2. Step-by-step deployment guide.
3. One-hour hand-off call or chat to walk through setup and answer final questions.

If you’ve built Telegram commerce bots before, mention it and share a sample. I’m ready to choose quickly and start right away.
