Commissioned during his internship tenure, Haikal architected a cross-platform HRIS encompassing both Flutter mobile and web clients. The system centralised employee management, attendance workflows, and payroll data into a single authoritative platform. The primary architectural goal was to resolve data fragmentation between administrative departments and on-field personnel.

The resulting software infrastructure utilizes a robust RESTful API backend powered by Laravel, handling relational operations in MySQL. The client applications are built on Flutter, utilizing the Model-View-ViewModel (MVVM) architectural pattern combined with Provider for state management to ensure fluid performance and decoupled business logic.

Iterative usability testing produced a System Usability Scale score of 74.42, classifying the product as "Good" — with a 93% Task Completion Rate across evaluation sessions. The web variant achieved Lighthouse Performance and SEO scores of 92 and 91 respectively, validating the optimization of client bundle sizes and server-side request routing.
