Tan HK • Procurement & AI Tool Builder

Building AI-Powered Tools for Procurement, Inventory & Productivity

I manage end-to-end procurement cycles and inventory operations, leveraging AI prompt coding to design Chrome extensions, web apps, dashboards, and security awareness tools that automate workflows, optimize stock levels, and enhance decision-making.

About Me

I am a procurement and inventory management professional managing the full end-to-end procurement cycle, including strategic sourcing, price negotiation, contract management, PR/PO issuance, vendor coordination, goods receipt, SAP 3-way match validation, and real-time inventory tracking.

Alongside my core role, I design and build lightweight, AI-powered tools using prompt coding to automate repetitive workflows, optimize stock levels, reduce manual effort, and enhance decision-making across procurement, inventory management, logistics, security awareness, and knowledge management.

My approach is grounded in practicality: every tool I create addresses a real operational pain point, deploys quickly without complex infrastructure, and delivers immediate value—so teams can focus on strategy, not administration.
