Payments System Design & Architecture

A deep dive into how real payment systems actually work.

Topics can be customized based on your needs:

1. Payment flows (PSP, issuer, acquirer)
2. Idempotency & retries
3. Tokenization (network vs PSP tokens)
4. Webhooks & eventual consistency
5. Failure scenarios & reconciliation
6. Security & compliance tradeoffs

Perfect if you:

1. Are joining a payments/fintech team
2. Want to ace fintech system design interviews
3. Work on checkout, money movement, or billing systems

This is industry-grade knowledge, not blog-level theory.
