David Cheungbuilds health systemsthat people trust.
I'm a full-stack software engineer with 4+ years delivering production web and mobile products across startup, university, research, and public-infrastructure environments — including a digital health platform serving 20,000+ users.
Engineering human-centred health software.
I take hands-on ownership across the whole lifecycle: translating requirements, building frontend and backend, deploying to the cloud, testing, and supporting live production. My toolkit centres on React, Flutter, Django, Flask, AWS, and Docker.
Beyond shipping features, I care about how software supports real care decisions, improves engagement, and connects users, families, clinicians, and care workflows in practical ways. I enjoy translating healthcare and research requirements into system designs, data flows, and production-ready applications.
My long-term direction is to work on digital health and AI-enabled systems for chronic disease management and proactive care — at the intersection of software engineering, health data, system analysis, and real-world healthcare needs.
