About Me

Data people can trust, code people enjoy.

I'm a Software Engineer at Infineon Technologies, working on enterprise data systems with Oracle PL/SQL, ETL and C# .NET. I turn complex requirements into reliable, usable software.

My background spans data science at AirAsia and TM R&D, and a Computer Science degree from UKM with First Class Honours.

I also build freelance websites for businesses, including Homestay Shimah Jay and Kambing Golek Melaka Official. Explore their interfaces and case studies in my web and application portfolio.
