Overview 🔗

A corporate banking portal for corporate clients of a major Indonesian bank. Provides corporate account management, cash flow monitoring, and approval workflows for business banking operations.

Role & Context 🔗

As a sub-contracted frontend engineer, I led the web frontend development and provided consultancy for the overall frontend architecture. The project required a polished, enterprise-grade experience with complex data flows and strict security requirements.

Key Features 🔗

Corporate Dashboard 🔗

Configurable widget dashboard displaying deposit totals, loan summaries, cash flow trends, and account activity from a corporate client’s perspective.

Approval Workflows 🔗

Maker/approver role-based approval system for corporate transaction workflows.

User Management 🔗

Corporate client user administration with role-based permissions.

Secure Authentication 🔗

RSA public key encryption for login credentials, CAPTCHA integration, and session management.

Build Notes 🔗

Security Requirements 🔗

Banking projects come with strict security requirements. Login credentials are encrypted client-side using RSA public key encryption before transmission — the server never sees raw passwords. CAPTCHA adds bot protection, and sessions are managed carefully to prevent hijacking.

Data-Heavy Dashboard 🔗

The dashboard displays deposit totals, loan summaries, cash flow trends, and account activity through configurable widgets. Chart.js renders the data visualizations, and react-intl handles bilingual support (English and Indonesian) since the portal serves both internal and corporate client users.

Widget-Based Layout 🔗

The home page uses a configurable widget system where different user roles see different sets of widgets. This means the same foundation serves multiple use cases without building separate applications.
