From IT operations to network architecture
I started in enterprise IT and network operations at PT Pertamina and its subsidiaries, working on topology redesign and IT-OT integration. That hands-on operational grounding is why I care about networks that are reliable first, clever second.
Pertamina is now sponsoring my MSc in Information & Network Engineering at KTH Royal Institute of Technology in Stockholm — a full-time tugas belajar scholarship. Coursework spans datacenter networks, wireless systems, queuing theory, and networked systems security.
Outside coursework, I build things I'd want to run in production: containerized applications, CI/CD pipelines, and the mail server this very page runs on.
Routing table
Skills, announced the way a router would announce them — where they lead, and how they're reached.
