Project Overview

A production enterprise HRIS mobile application developed to support employee attendance, HR operations, and internal business workflows. I joined the project during the v3 development phase, working as part of a cross-functional team to enhance UI, improve user flows, extend features, and strengthen the existing architecture while managing the release and update lifecycle.

My Contributions

Refactored and enhanced UI components for attendance, leave, and overtime modules
Improved user flow consistency across 20+ screens following design system guidelines
Implemented push notification handling for HR workflow updates
Managed OTA updates via Shorebird, reducing Play Store dependency
Collaborated with backend team on API integration and error handling improvements

Challenges & Solutions

Key engineering problems I solved during this project.

Evolving a Live Production App to Version 3

Collaborated with business analysts, backend engineers, and a team of Flutter developers to refactor UI and user flows while preserving existing functionality and ensuring a smooth transition for users.

Complex and Interconnected HR Workflows

Implemented and enhanced structured workflows for attendance, leave, overtime, appraisal, business trips, and maintainable architecture.

Maintaining Scalability in a Growing Codebase

Applied Bloc state management and dependency injection patterns to improve code clarity, predictability, and long-term maintainability as new features were introduced.

Efficient Release and Update Management

Handled application packaging, deployment, and over-the-air updates using Shorebird, enabling faster iteration cycles and reducing reliance on full app store releases.

Outcome

The HRIS application evolved into a more maintainable and scalable platform with improved user experience, clearer business workflows, and a faster release cycle. These improvements strengthened daily employee operations and positioned the product for continued growth with controlled technical debt.
