At Centrix Technologies, I developed account modules and maintained Active Report sales and purchase invoice reporting for the Leader Food client. I also wrote stored procedures and SQL queries to support new web forms.
For Iras, I built automation to submit payroll details to the Singapore Government portal and implemented a Web API bridge to return government-site responses to the internal development environment. I handled JSON data exchange and implemented Content Security Policy changes across the codebase.
For Patek Philippe, I maintained Crystal Reports for invoicing and built an Excel-to-database import process. I also enhanced payroll reports and calculations for Centrix Software Solutions.
