Online Banking System
Full-stack digital banking — accounts, loans, cards, and investments.
Overview
YourBank is a comprehensive online banking solution built with Flask. It models the core of a retail bank: multiple account types, transfers, loans, credit cards, investments, and security controls — all behind a single authenticated experience.
Beyond simple balances and transfers, the system handles automated EMI processing, bulk payments, GST/tax payments, email notifications, and downloadable statements (CSV/Excel). Dashboard analytics surface transaction history and account health.
Security is treated as a first-class feature: password hashing, two-factor authentication (PyOTP), CSRF protection, and mail-driven notifications for important account activity.

Real-world usage
Where this kind of system shows up outside a portfolio context.
- Teaching and demonstrating end-to-end banking product workflows
- Prototyping FinTech product ideas (loans, cards, investments) before mobile apps
- Campus labs simulating multi-module enterprise banking systems
- Portfolio proof of complex domain modeling, auth, and scheduled jobs
Challenges
- Modeling many financial entities without inconsistent ledger-like states
- Scheduling reliable EMI and notification jobs alongside request handlers
- Balancing feature breadth with a clear, navigable UI
What I learned
- Domain models (accounts, loans, investments) drive architecture more than frameworks
- Security layers (2FA, CSRF) should be designed early, not bolted on
- Background jobs make “real banking” behavior feel production-like
