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.

The Medical Suite

live

Six connected apps, each covering one dimension of personal health — sharing one Google sign-in and keeping every record in the user's own Google Drive, never on my servers. Switch between them from a shared app menu; together they build one longitudinal picture that Prognos reads across.

clinical data

Hemoto

bloodwork & labs · report parsing

Turns a photo or PDF of a lab report into structured, trackable bloodwork — every marker with its reference range, trended over time so a slow drift is visible long before it becomes a number out of range.

emergency medicine

Aegis

medications & SOS · Google login

Your current prescriptions and a printable emergency SOS card — the critical info a first responder needs, auto-derived and publishable to a private link. Includes the daily medication checklist; data stays in your own Drive.

Vitals

wearables & physiology · Withings, Oura

Connect a wearable and pull body-composition, sleep and cardiovascular signals into one snapshot with longitudinal trends. Bring-your-own cloud through a provider-agnostic connector — your data never leaves your account.

visit vitals
nutrition

Trophe

intake & routine

Log meals against a daily routine and let an on-call model estimate the nutrition — so intake gets tracked without weighing and looking up everything. Installable as a mobile app.

synthesis

Prognos

trends & risk foresight

Reads across the whole suite — labs, medications, physiology, intake — to surface trends and early-warning signals in a single, prevention-focused view. The layer that turns tracking into foresight.

visit prognos
mental health

Thymos

mind, mood & stress

A mobile-first mood and stress journal with reminders — the psychological dimension logged alongside the physical, so the two can be read together over time. Installable as a mobile app.

health

self-tracking · health.sankhacooray.com

A personal Withings Body Scan dashboard — every body-composition metric from the scale and a ScanWatch 2, with weekly and monthly trends. Now served by a Cloudflare Worker that keeps the Withings secret and rotating token server-side.

doctorlanka

channelling helper · invitation only

A faster weekly calendar over Sri Lanka's doctor channelling — compare doctors, hospitals and session times at a glance, then finish on the official site. Ships as a Chrome extension, available by invitation.

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.
