Mega Open API Portal

Context

Enterprise API exposure and governance platform for Bank Mega. As IT Architect and API Governance Lead, designed the developer portal for internal and external API access.

Problem

API integration patterns were inconsistent across teams. Lack of centralized documentation made onboarding difficult. No clear ownership or lifecycle management for APIs.

Constraints

• Enterprise SSO integration (LDAP)
• Role-based access control requirements
• Observability and audit logging
• Support both internal and external consumers

Architectural Decisions

Built centralized portal for API discovery, documentation, and access management. Implemented RBAC for granular permission control. Integrated with existing enterprise authentication.

Added lifecycle management features—versioning, deprecation notices, and migration guides. Centralized logging for API usage analytics.

Tech Stack

Next.js (Frontend), Laravel/Node.js (Backend), LDAP/Enterprise SSO, Nginx, Linux, Centralized logging.

Outcome

Standardized API integration patterns across organization. Reduced integration ambiguity and onboarding time. Improved auditability and ownership clarity.

What I'd Improve Next

Would add API mocking for development workflows. Consider GraphQL federation for complex data requirements.
