About.
Who I am, what I run, and how I work — with clients and with my own homelab.
Leading ICT at PT Sentosa Laju Sejahtera. Rolling out Odoo Community, integrating SAP B1 with internal ERP, and hardening the org-wide security posture.
ICT Manager, infrastructure & security, from Sidoarjo.
I'm Irfan Haris. 17+ years in IT infrastructure, security, and project management — from mining-site networks in Kalimantan to monitoring and SIEM at a large Indonesian retail group. Now leading ICT at PT Sentosa Laju Sejahtera.
Interests: IT infrastructure, IT security, IoT, data analysis, and automation. Open-source first, self-hosted where it makes sense, calm about it.
