At Mediacorp Pte Ltd (via BusinessIT), I replaced manual screenshots with a read-only Python scanner that generates draw.io network diagrams. I mapped 41 AWS accounts across three AWS Organizations, then extended the scanner to Azure and Google Cloud.
I also turned route tables into traffic-flow maps and flagged unused VPC peering and untagged resources. I prepared a handover guide, management deck, and security-review pack for an AI agent pilot.
As a freelance full-stack developer, I built and launched a B2B booking platform for Trust Asia Tours using Next.js, TypeScript, and PostgreSQL. It includes agent and staff portals, role-based access control, payments, and AI package matching.
For Trust Partners, I turned a whiteboard sketch into an approved 25-page prototype and then a custom WordPress plugin. At Nanyang Polytechnic, I built an intergenerational community website on Google Cloud; its pilot involved 50 users and received a Good Presentation Award.
