Past Projects

Some noteworthy projects that combined engineering depth, regulated environments and complicated systems and data flows.

LinAge2 / Commercializing biological ageing clocks

Clinic management system & biological age reports

Turning LinAge2, a biological aging clock developed at NUS, into a production-ready service that's deployed in clinics.

Built a platform to generate biological age reports and manage clinics, from scratch. Along with health data compliant AWS cloud infrastructure.

Better Medicine / Radiology platform

AI Augmented medical platform for radiologists

Built and maintained a web-based imaging viewer, integrated AI results into radiologists' workflows, and developed secure data-transfer infrastructure for medical deployments.

Helped certify the viewer as a medical device and co-authored peer-reviewed kidney-cancer AI research in Communications Medicine.

Pixme AI / AI model finetuning platform

A platform to train AI image generation models

Built an ai model training and image generation platform with user friendly UI/UX

The work involved building a full-stack application with a complicated end-to-end image processing and AI model training pipeline.
