At Indosat Ooredoo Hutchison, I develop and maintain an ESME microservice that connects other services to the SMSC over SMPP. I also work on the MyIM3 Kiosk backend and services for eSIM purchases, migrations, and transfers.
At Fibr Corp, I contributed to a C++ framework for object lifetime management and research on a compiler that generates optimized C++ code for it. I also proposed and carried out restructuring and refactoring of a Flutter code generator in a no-code platform.
At Paques Indonesia, I developed a multithreaded processing pipeline and backend for a big data platform. I built tools for loading call event data and converting geohashes into custom-sized tiles, and proposed a geospatial method that was adopted in production.
My other work includes refactoring the HCEnabler employee management system for Telkom Akses and developing employee salary management software for Yayasan Pendidikan Jamiat Kheir. I’m also developing libsmpp5, an open-source C library for the SMPP 5.0 protocol.
