A research lens on
biology and medicine.

Side projects, collaborations, and small tools at the edge of bio-engineering, medical informatics, and biosensing — built from the outside by an engineer who likes asking biologists hard questions.

About

I'm an engineer who keeps ending up adjacent to biology, medicine, and biosensing. Sometimes that means a side project with a clinician friend; sometimes it means writing software for a research lab; sometimes it's just my own curiosity about a measurement I don't yet understand.

This page is the lens — a place to gather those threads in one view, so the bio-medical work doesn't get lost among the rest of the projects I do.

Most of the work here is collaborative or instrumental: building the tool, the dataset, the dashboard, the deep-link, the analysis script — so the people doing the actual clinical or biological work can move faster.

New projects will be added as they reach a state worth showing — with the appropriate consent, anonymisation, and framing.

Areas of Interest

The recurring threads — where engineering instinct meets a biology or medicine question.

Medical informatics
Patient records, history tracking, longitudinal data tools — the unglamorous backbone of care.
Biosensing
Wearables, body scans, and the messy business of turning a signal into a number you can trust.
Medication analysis
Tooling around prescriptions, side effects, and visualising treatment timelines.
Healthcare access
Channelling, booking, and friction-removal — small interfaces between patients and systems.
Bio-engineering
Hardware-adjacent work where a folded paper structure or a small device meets a body or a sample.
Research tooling
Scripts, dashboards, and one-off interfaces for collaborators in clinical and lab settings.

Selected Projects

private / in progress

A few of the bio-medical side projects from the workspace. Most are private repositories — descriptions only, with links added where the work is published.

medical informatics

Medical history tracker

private project · family use

A small longitudinal record tool — appointments, prescriptions, scans — built for a single patient's care continuity.

private
biosensing

Withings body-scan integration

personal data tooling

Connecting Withings body-composition scans to a personal data view — long-term trends instead of single-day readings.

private
medication

Hair-medication analysis

analytical side project

Visual analysis tooling for hair-related medications — interactions, timelines, and the patterns a spreadsheet doesn't show.

private
access

eChannelling interceptor

healthcare booking · Sri Lanka

Tooling around the eChannelling appointment system — friction removal for booking with specific doctors in Sri Lanka.

Working Principles

A handful of rules I try to keep when the work touches a body, a patient, or a clinician's decision.

Engineer, not clinician
The tools are for clinicians and researchers to use — never a substitute for their judgement.
Consent first
Anonymisation, scope, and the right to walk away — agreed up front, not after the dataset exists.
Reversible by default
Any tool that touches a record should be auditable, exportable, and undoable.
Small, local, private
Prefer local-first storage and minimum-collection design until the use case demands otherwise.
Note. Nothing on this page or in linked projects is medical advice. The work here is engineering and tooling around medical contexts — decisions about diagnosis, treatment, or medication should always come from a qualified clinician.
