Curious
by practice.
I’m M Rival Setiawan, a late bloomer from Jakarta. I make useful systems, pay attention to ordinary details, and learn in public—one experiment at a time.
EngineeringI turn unclear ideas into working systems with explicit boundaries and evidence.
PhotographyI photograph light, streets, and overlooked moments.
CommunicationInternational customer work keeps technology connected to the person using it.

Customer Service Specialist
Supporting customers internationally sharpened how I communicate technical systems: clearly, patiently, and from the person’s side of the screen.
View experience on LinkedIn05 · Team practice
Two people.
One accountable loop.
Silent Protocol is the two-person team behind a growing security and automation platform for online communities. We keep engineering, security, design, and support close together—so the people making the system remain close to the people using it.
“Ship what works. Be clear about what is still in progress.”
We move deliberately: a few things done well, with direct ownership from product decisions through operations and support.
