Backend and industrial IoT engineer

Muhammad Jafar Ikbal

I build the systems that move industrial data: OPC UA and IEC 104 front-end processors, notification gateways, Kafka pipelines, and the dashboards on top.

Currently Software Engineer at PLN Icon Plus (contract), working on SCADA platform services. Based in the Jakarta area, open to remote.

About

I have spent the last years between two worlds: operational technology (SCADA, PLCs, IEC 60870-5 protocols, OPC UA) and modern backend engineering (Python, Go, Java Spring Boot, Kafka, PostgreSQL, Docker). My job is making those two talk to each other reliably.

At PLN Icon Plus I built and maintain industrial communication services: an OPC UA front-end processor, a smart modem service, and a digital SMS notification gateway. Before that I worked on HRIS backends and application QA at Mutiara Solusindo.

I prefer boring technology that can be monitored: small binaries, clear protocols, tests, and logs that explain themselves.
