A centralized business operations platform built on backend integrations, middleware services, scheduled notifications, and database-driven processing — ensuring smooth and efficient airport operations across multiple operational teams.

5DCC — Airport Operations Platform

5DCC is an enterprise operational management platform used to support airport operations at Hong Kong International Airport. The system manages operational workflows, coordination, data monitoring, reporting, and communication between multiple airport teams and services.

A native Android Wear OS application that delivers real-time notifications, task synchronization, and operational workflow interactions to frontline staff — improving mobility, responsiveness, and communication efficiency during daily airport operations.

iWatch — Smartwatch Companion

iWatch is a smartwatch extension of the iStaff ecosystem developed to support real-time airport operational activities at Hong Kong International Airport. Designed for operational staff to receive instant notifications, task updates, and operational messages directly from wearable devices.

Built with Flutter & Dart and designed with responsive UI/UX, Bujishu integrates with backend services to support product management, customer interactions, and complete order workflows — all wrapped in an elegant dark gold-accented brand experience.

Bujishu — Furniture E-Commerce

A cross-platform e-commerce mobile application focused on furniture and home living products. Users can browse products, manage shopping carts, place orders, and enjoy a modern mobile shopping experience.

Built with offline-first architecture so warehouse and operational staff can keep working even without internet connectivity. The app captures all activity locally, then synchronizes with backend systems the moment the network is back — essential for fast-moving logistics environments.

Linehaul — GDEX Logistics App

A native Android logistics application for GDEX that supports linehaul operations between logistics hubs. It manages loading and unloading of parcels and cargo during hub-to-hub transportation — helping operational staff track and process shipments efficiently in real-time.

Designed for field couriers operating across Malaysia, KITA captures every delivery action — scan, handover, claim — and works seamlessly even when network coverage drops. The moment a courier is back online, all activity is silently synchronized with the backend, ensuring no shipment goes unaccounted for.

KITA — GDEX Courier App

A native Android mobile application for GDEX that supports courier delivery operations from logistics hubs to end receivers. KITA empowers couriers to manage parcel delivery workflows, shipment tracking, and delivery status updates efficiently throughout their daily operations.

Built around a tactical command-center aesthetic, Stratagem lets players take on roles like Strategist or Ambassador, coordinate factions, deploy units across regions, and engage in multi-phase warfare. The system simulates real strategic dynamics — alliance status, threat levels, region control, and operational funds — all wrapped in a real-time multiplayer environment hosted on AWS.

Stratagem — Strategic War Simulation

A browser-based multiplayer strategic war simulation game designed for training and simulation purposes. The platform features turn-based gameplay mechanics, strategic decision-making systems, operational planning modules, and real-time player interactions — simulating mission execution, operational coordination, and foreign influence scenarios within a competitive strategic environment.

Designed as a scalable, multi-tenant backend infrastructure using Node.js and MySQL, with advanced middleware services for API gateway, authentication, message queuing, and data synchronization. This backbone ensures seamless communication between web, mobile, and wearable platforms while maintaining data consistency and real-time updates across all operational systems.

Backend & Middleware Services — Multi-Platform Integration

Core backend and middleware services architected to support 5DCC (web operations platform), iStaff (mobile workforce app), and iWatch (smartwatch companion). A unified API layer providing real-time data synchronization, task management, authentication, and operational coordination across all three client applications.

Cross-platform mobile app (iOS & Android) that integrates with backend systems and APIs to improve operational efficiency, communication, and workforce mobility across airport operations.

iStaff — Mobile Workforce Management

iStaff is a mobile workforce management application supporting operational staff activities within Hong Kong International Airport. Staff can access operational information, receive notifications, submit and retrieve real-time data, and coordinate daily airport-related activities through mobile devices.
