Co-Founder, Temika Cyber · Jakarta

I build infrastructure that stays up and stays secure.

For over ten years I have run cloud, DevOps, and security for companies in media, healthtech, and nationwide logistics. I care about systems that hold up at 3 a.m., and teams that can fix them without me in the room.

About

Systems that hold up. Teams that keep them that way.

I am Co-Founder of Temika Cyber and have spent the last decade building and securing cloud infrastructure, from media and healthtech to nationwide logistics. Most of that work is invisible when it goes right, which is exactly the point.

The hard part was never the technology. It is building teams who understand the systems well enough to fix them under pressure, and giving them the room to grow into it. I would rather ship something the team can actually operate than something clever nobody can touch.
