About This Project

Build a Real-World
FinTech Banking System

This is not a toy project. You will build FinBank — a production-style digital banking platform that handles customer onboarding, accounts, fund transfers, cards, payments, transactions, notifications, and secure banking workflows.

Students architect this using microservices patterns, implement secure REST APIs, use Redis caching and messaging, integrate payment and notification workflows, and deploy via Docker containers on AWS. The result? A portfolio piece that demonstrates real banking engineering skills.

By the end, you will have handled real-world banking challenges like secure money transfers, transaction consistency, KYC workflows, fraud checks, audit logging, distributed notifications, and automated CI/CD with GitHub Actions.
