King Chan — Systems & Integration Engineer
$ cat about.txt
Systems and integration engineer based in Hong Kong. My work lives where systems have to meet each other: HL7 interfaces between clinical systems, computer vision supporting laboratory analysis, warehouse and content platforms, cloud infrastructure, and the automation that removes the manual steps in between. I care about the unglamorous parts — data that arrives intact, failures that surface instead of hiding quietly, and handover documentation the next person can actually follow.
$ ls ./skills
Integrated a clinical system with Hospital Authority HL7 interfaces so patient demographics, orders and results flow between systems automatically, with reliable delivery and a full audit trail.
Lifted a company's on-premise ERP and file servers into AWS — Terraform-managed, encrypted, and 30% cheaper than the hardware refresh they were quoted.
Built a computer-vision pipeline for blood film images — segmenting and classifying cells to support differential counts, with uncertain cases escalated to a human rather than guessed.
Implemented a warehouse management system covering receiving, putaway, picking and stock counts — barcode-driven on the floor and reconciled against the finance system.
Designed and built a CMS so non-technical staff can publish and update content themselves, with structured content types, roles and a review step before anything goes live.
Built a fast, static-first e-commerce site with Stripe payments for a local brand — sub-second loads, 99+ Lighthouse, zero servers to maintain.
Turn the data you already collect into decisions. Dashboards, forecasting and AI-assisted analysis that answer business questions instead of producing more spreadsheets.
Migrations, greenfield builds and cost optimization on AWS, Azure and Microsoft 365 — architected for reliability first, invoices second.
Firewalls, endpoint protection, hardening and tested backups. The goal: make a bad day recoverable and a breach unlikely.
Take the repetitive steps out of the working day. Approvals, hand-offs, data entry and routine reporting run on their own, with a clear trail when something needs checking.
Fast, static-first websites and internal tools. Built with modern frameworks, deployed on edge platforms, no server babysitting required.
Technology strategy for businesses without a CIO. Roadmaps, budgets, vendor management and honest advice on what not to buy.
