Projects
Intex Networking Sdn Bhd
Automation / Web Scraper
A scraper-driven reporting pipeline built to extract operational and financial data from multiple back-office systems for internal reporting.
Challenge
The main challenge was building a scraper flow that stayed reliable across fragile back-office systems, where small changes in login, navigation, or page structure could break reporting.
Newsoft IT Solutions Sdn Bhd
Chatting Web Application
A web messaging platform with 1-to-1 and group messaging, designed to handle large data volumes and performance-sensitive conversation flows.
Challenge
The key challenge was keeping the messaging experience responsive while handling large volumes of conversation data without overloading the client or increasing API pressure unnecessarily.
Digital Savvy Sdn Bhd
Health Savvy Full Stack Platform
A cross-platform healthcare product spanning mobile app, web platform, and backend services for clinic discovery, booking, telemedicine, and payments.
Challenge
The platform had to be delivered across three very different layers at once: a new Flutter mobile codebase, a legacy Vue web platform, and a legacy .NET backend that also required upgrade work.
Freelance
Airasia Minigames
Backend work for Airasia minigames including Point Catcher and Biggie Wonderland, with reward-odds logic, points integration, and deployment support.
Challenge
The main challenge was stabilizing reward and points logic in production, including double payouts, incorrect reward weighting, and concurrency-related race conditions. It also required improving error logging so failures could be traced clearly when issues originated from the Airasia vendor API.
WTF Synergy Sdn Bhd
Remote Game Server (RGS)
Worked on a .NET-based remote game server platform for real-time digital game products across 10+ microservices, supporting feature work, platform architecture, deployment improvements, and R&D proof-of-concept work for new product ideas.
Challenge
The main challenge was contributing within a larger multi-service team environment, where delivering safely required alignment on shared standards, cross-team communication, and API contract expectations.
