At O-Four Digital Convergence Ltd, I run an independent IT services and consulting practice covering infrastructure, software, and security-focused engagements. I executed five end-to-end ERP implementations and multi-site CCTV deployments across three sites.
I also manage client infrastructure projects from site survey through approval and handover, including vendor sourcing, pricing research, and procurement. My work spans education and healthcare, where I’ve supported device fleets, networked systems, and IT operations.
At Holy Child College, I managed more than 110 Windows devices and developed a knowledge base for common technical issues. I’ve also administered an air-gapped on-premises server, implemented RBAC and least-privilege controls, and supported data labeling for NLP and computer vision models.
