Mardino Santosa · MakassarSheet 2026
Networks that stay up. Apps that ship.
I'm Mardino Santosa — zdienos. Since 2007 I've been the person called when the network drops, the server fills up or the team needs an internal tool. Physics graduate, former lecturer, ten years running IT at a theme park, and a full-stack developer as well. Since 2023 I work independently, as a freelance software developer in Makassar.

05For hire
For hire.
You already have the source code. You need someone independent to maintain, fix, migrate or extend it — and to look after the server it runs on. That is the work I take on, directly, without a software house in between.
