A minimal Telegram bot designed to streamline payment collection for small sellers. The bot collects product details directly in chat (name, quantity, price, currency) and generates a Stripe Checkout session link for one-time payments. Built as a framework-free Java application focused on simplicity, low resource usage, and portable deployment, including ARM32 Docker builds for Raspberry Pi hosting.

Purpose: Enable quick payment link creation directly from Telegram without building a full storefront UI.

Bonus: Used this project to experiment with multi-architecture Docker image builds (ARM32 for Raspberry Pi) and validate how far a small, framework-free Java service can go in terms of memory efficiency and operational simplicity.
