About William W
I have spent over ten years in IT infrastructure and security, not as an interest alongside development work but as the job: running cloud, monitoring, ITSM and device management for organisations that stop working when those stop working.
Today I act as IT Manager for a client's 40-person IT support team, alongside a senior IT role at a Malaysian software company. I led a company-wide migration from Google Workspace to Lark end to end, and I build internal systems in which AI agents carry part of a multi-role workflow. Earlier, e-commerce logistics at J&T Express Malaysia (an operation where a system being down is counted in undelivered parcels) and ISO 27001-aligned security and IT audit work.
That is why WilliamW Resources delivers the whole chain rather than just the code. Monitoring, access control, backups and the security review are not extras I picked up for this website; they are what I have been paid to do for a decade.
How I work
- You always see a live demo before anything goes to production.
- Fixed, written scope per milestone: no surprise invoices.
- You own the source code and the infrastructure accounts.
- I communicate in English and Chinese, whichever you prefer.
