Healthcare is ultimately a systems problem. Medicine identifies problems, research validates solutions, and technology scales impact.

The story

Why medicine and software

01 · The origin

Seeing the system

I chose medicine for the obvious reason — I wanted to treat people. What kept me in it was something I noticed on the wards as a student in Dar es Salaam: most of what goes wrong for a patient never happens at the bedside. It happens in the gaps — a file that can't be found, a result that arrives late, a referral that stalls between desks. The patient in front of you is one person; the system around them decides what care they actually receive. Once I saw healthcare that way, I couldn't unsee it.

02 · The pattern

One skill, two systems

Long before the wards, I was the person people brought broken computers to. Years of freelance IT work taught me a method: reproduce the fault, isolate the layer, change one variable at a time, fix the cause — not the symptom. Clinical medicine turned out to run on the same discipline. Working through a differential, ruling things out test by test, is the same systematic isolation of root cause. The two skills I thought belonged to separate lives were one skill, applied to two kinds of systems.

Diagnosis and debugging are the same discipline: isolate the cause, then fix the system.

03 · The mission

Multiplying medicine

Medilog is where the two converge — a hospital management system I'm building from inside clinical practice at Consolata Hospital Ikonda, shaped by the records I actually handle and the workflows that actually break. As one doctor I can see perhaps forty patients in a day. Software that removes friction for a whole facility touches every patient who walks through the door. That is what scaling impact through technology means to me in concrete terms: not leaving medicine — multiplying it.

Life in frames

The fuller picture

Medicine and software are most of the story, not all of it. A glimpse of the rest — the travel, the people, and the in-between.

The road so far

The path

Two threads — medicine and software — that took a while to recognise as one. Here is how they ran, and where they finally met.

2019 – 2024
Medical school
Catholic University of Health and Allied Sciences (CUHAS), Mwanza
Five years where the question that still drives me first formed: not just how to treat the patient in front of me, but why the system around them so often gets in the way.
2022 – present
Technology freelancing
Self-employed
It started in 2022 with building PCs and tinkering with hardware. The broken-computer person became the build-the-thing person — self-taught systems work for real clients, from repairs to Linux migrations on Fedora — and it taught me to debug a problem to its root before touching a fix.
2024
MD dissertation research
CUHAS, Mwanza
A controlled comparison of gastrointestinal symptoms in autistic and typically developing children — the work that taught me to argue from evidence, treating a claim the way you treat a differential and ruling it out test by test.
Dec 2024 – Dec 2025
Clinical internship
Shinyanga Regional Referral Hospital
A year rotating through internal medicine, surgery, obstetrics, paediatrics, and emergency care — the wards at full volume. Most of what I now want to fix in healthcare, I first saw breaking here.
2026 – present
Clinical practice
Consolata Hospital Ikonda
Practising medicine in Tanzania's southern highlands, close to where care is hardest to deliver — and where the gaps software could close are most obvious.
2025 – present
Building Medilog
A hospital management system built from inside clinical practice, shaped by the records I actually handle. One doctor sees forty patients a day; software that removes friction touches every patient who walks in.

What I'm building

The work

Medilog is the center of gravity. The projects around it are smaller, but they point the same way: systems that hold up under real clinical work.

In active development· June 2026

Medilog EHMS

An electronic health management system built from inside Tanzanian clinical practice — patient records, workflows, and reporting without the paper chase.

The problem — paper-first records fragment care: missing files, late results, and clinical hours lost to documentation and manual reporting.
The approach — design from the ward outward: every module traces to a real workflow at a Tanzanian hospital, not a generic EMR template.
Where it stands — patient registration and clinical documentation in active development; the other modules are mapped and honestly labeled planned.

Read the story

Diagram of one patient visit: five steps from reception to pharmacy, each annotated with its paper-workflow pain point, connected to a single shared Medilog patient record that feeds reporting, audit, and continuity of care.

Research· May 2026

Clinical Audit Toolkit

Structured data capture for ward audits and quality-improvement reviews — working out how audit-ready data should flow from everyday clinical records.

Shipped· September 2025

Fedora Migration Playbook

A documented, repeatable process for moving individuals and small offices from Windows to Fedora Linux — install, data, and the follow-up that makes fixes last.

Research· September 2024

GI Symptoms in Autism: A Mwanza Study

A cross-sectional study of gastrointestinal symptoms in autistic children in Mwanza, Tanzania — what it measured, and what the findings argue for.

How I can help

The craft

The same diagnostic thinking I use in medicine, applied to machines: isolate the root cause, fix the system, prevent recurrence.

PC & Laptop Diagnostics
Slow, crashing, or failing hardware root-cause diagnosis and a machine that stays fixed.
Smartphone Support
Software faults, storage chaos, a phone that fights you clean software, safe data, a device that keeps up.
Hardware Diagnostics
Intermittent faults nobody can pin down component-level isolation, so you replace the part — not the machine.
Linux Systems
Windows holding old hardware (or a new server) back Fedora installation, configuration, and a migration that sticks.
System Optimization
A setup that degrades a little more every month performance tuning and maintenance that extend a machine's life.
