Cahya Putra
Senior DevOps engineer at Pajak.io, where I keep a national tax platform deploying and observable. Alongside it I build the products themselves — exams, collections, agriculture, government — and then run the infrastructure they live on.

What I take on
Most jobs start as one of these four and end up touching all of them.
-
Web & platform development
End-to-end product work — data models, APIs, dashboards, and the admin panels somebody has to live in every day.
-
Infrastructure & DevOps
Provisioning, hardening, and CI/CD, so a merged branch reaches production without anyone SSH-ing into a box at midnight.
-
Automation & scripting
Scheduled jobs, backups, reports, and integrations that quietly delete the manual step nobody wanted to own.
-
Networking & IoT
Routing, segmentation, and device-to-dashboard telemetry — from the switch port all the way to the chart.

Profile
A short version
I started on the network side — MikroTik routing, switches, the physical layer — and worked up through servers and security into building the applications that sit on top. That path is why I tend to be the person who ships the feature and knows why the deploy failed.
Since 2018 I've done that for agriculture, fintech collections, exams, retail, government, a university, and the Army — fourteen systems on this page, most still running, all of them deployed through CI/CD rather than an FTP client.
Lately that has extended to AI tooling: agent workflows, the Model Context Protocol, retrieval pipelines, and using coding agents as part of day-to-day engineering rather than a demo. I also spend time in Hack The Box labs to keep the security half sharp.
