Message

At InterSystems, I led pre-sales and solution delivery across Southeast Asia, designing technical architectures for big data, healthcare interoperability, and enterprise integration. I worked with clients and partners across healthcare, financial services, and logistics.

I architected and presented proofs of concept using FHIR, HL7, and APIs to demonstrate platform capabilities. I also planned and facilitated technical workshops on interoperability standards and digital health implementation.

As a Graduate Teaching Assistant at Heinz College Carnegie Mellon University, I supported graduate students in optimization, decision modeling, and data visualization through office hours and review sessions.

At InterSystems Asia Pacific, I built a FHIR-enabled interoperability prototype with ObjectScript, Python, and SQL, and created real-time dashboards and geospatial pricing maps in RStudio. I also hold a Professional Scrum Master I certification.
