Hi Dev Community 👋

I recently completed a project called Online Banking System, and I’d love to share my journey, challenges, and also invite you to test it out and give me feedback.

💡 Why I Built This Project

I wanted to simulate the core functions of a banking application — not just as a coding exercise, but also to understand the challenges of security, data handling, and user experience. Banking systems are everywhere, but behind the scenes they require careful design.

🏗️ How I Approached the Project

1.Planning the Features – I listed essential features like account creation, fund transfer, transaction history, and an admin panel.

2.Designing the Architecture – I chose Angular + MySQL + Spring Boot.

3.Building Step by Step – Started with authentication, then account management, then transaction logic.

4.Security Considerations – Implemented encrypted passwords, session handling, and input validation.

⚡ Challenges I Faced

1.Data Consistency: Making sure transactions update correctly and rollback on errors.

2.Authentication & Security: Handling login safely without exposing vulnerabilities.

3.UI/UX: Designing a simple but effective interface that users can understand quickly.

4.Error Handling: Ensuring smooth handling of failed transactions or invalid inputs.
