Hi everyone,

I'm currently learning FastAPI and planning my first major backend portfolio project. I'd really appreciate your feedback before I invest a few months building it.

The idea is to build a SaaS that integrates with Salla (the Shopify of the Middle East) using OAuth and Webhooks, along with the Telegram Bot API.

The workflow would be something like this:

• A customer purchases a digital product from a Salla store.
• Salla sends a webhook when the payment is confirmed.
• My FastAPI backend verifies the order.
• It retrieves an available license key/account from the database.
• The customer receives it automatically through a Telegram bot.
• Store owners also have a dashboard to upload inventory (CSV), manage products, and monitor deliveries.

Technologies I plan to use:

• FastAPI
• PostgreSQL/MySQL
• SQLAlchemy
• OAuth
• Webhooks
• Telegram Bot API
• JWT Authentication
• Pytest
• Docker (later)
• Deployment on Render/Railway

My questions are:

1. Does this sound like a realistic first major backend project?
2. Is it too ambitious for someone who has just finished learning FastAPI?
3. If you were interviewing a junior backend developer, would a project like this stand out compared to typical CRUD portfolio projects?
4. Are there any major architectural mistakes or challenges that you think I should know about before starting?

I'd appreciate any honest feedback. Thanks!
