About Me
Linux engineer, open source advocate, and technical educator based in Singapore.
Working with Linux and open source since the late 1990s — from package maintainer on Ark Linux to enterprise consultant, SUSE Certified Instructor, and Red Hat Certified System Administrator.
Today I work as Technical Manager at Transcend Solutions and Technical Lead at FOSSTECH Solutions, delivering pre-sales, implementation, and training across RHEL, SUSE, Ansible, OpenShift, Rancher, Kong, and more.
Outside of client work, I write on blog.dtio.app, post on YouTube, and build small tools under dtio.app.
