Backend Developer
Backend development for software that can't go down.
I'm a backend developer shipping reliable, secure code for hospital information systems.
01 — About
Background
I'm a backend developer. I build the parts of hospital software that nobody notices until they break, mostly in Node.js and Golang. Closing security holes. Keeping data consistent when everyone hits the system at once. Shipping updates without breaking anything. That's the job.
These days I also lead the Support team at PT Data Integrasi Inovasi, where I set how we fix, escalate, and hand over. Hospitals can't take a day off, so I build with that in mind.
