About Me

Data people can trust, code people enjoy.

I'm a Software Engineer working as an L3 Master Data Solution Developer at Infineon Technologies, where I keep worldwide engineering databases accurate, available and fast. My day looks like Oracle PL/SQL packages, ETL and data warehouse fixes, C# .NET enhancements and weekly Jenkins releases.

Before Infineon I trained as a data scientist — XGBoost forecasting at AirAsia, Random Forest and LSTM network models at TM Research & Development, and a HoverNet deep-learning final year project at UKM, which I finished with First Class Honours.

Outside the enterprise world I freelance as a web developer, shipping Next.js and TypeScript sites with real SEO, real analytics and rule-based chatbots — including the one sitting in the corner of this page. Say hello to it.

Enterprise Master Data Migration & Cleansing

SAP-related migration and de-duplication across Infineon's worldwide engineering master data. PL/SQL packages merge golden records, an ETL layer validates every load, and KNIME workflows automate the repeat tickets — around 30% less manual workflow and 50% less handling time on recurring data patches.
