Selected work
Field delivery and original research first. Methods-lab demos are labeled and kept secondary — they never outrank programme systems you can open and inspect.
Georgetown gui2de · Health financial diaries
Diaries systems: 300 households, one year
HFCs, automated quality workflows, an RA leaderboard, and a fuel/issues app that aggregated field problems in real time as data streamed into the study database.
Application · IRC Re:BUiLD · gui2de
Cash-plus targeting recommender
Shiny decision-support for IRC field teams. Application layer from causal forest targeting models — Cash vs Cash + Network with cost-aware rationale. Live app.
KEMRI · Oncology data systems
Kisumu cancer surveillance dashboard
Research data management for multi-year oncology records: REDCap architecture, quality systems, survival analysis, and a county-facing dashboard launched with local leadership.
MSc research · Forthcoming BMC Public Health
Financial determinants of NCD care in rural primary facilities
Mixed-methods study across seven public primary care facilities in Seme Sub-County: facility decision space, stockouts, and financing architecture for hypertension and diabetes care.
Manuscript data snapshot from 7 facilities
Operations framing · Health financing
NCD financing as an operations problem
Reframes the Kisumu chronic-care financing work for strategy and operations audiences: bottlenecks, levers, and scenario logic.
Public essay · Health systems
When clinics can diagnose but cannot buy medicines
Plain-language argument from the BMC paper: budgets, approval chains, and facility decision space.
Labeled demonstrations and tooling samples. Useful for methods conversation — not primary programme evidence.
Demonstration · ETL
ETL pipeline architecture
How raw survey and facility extracts move into validated reporting layers with reproducible R workflows and QA rules.
Live dashboard · Real open data (UCI, CC BY 4.0)
Customer intelligence & decision analytics
An end-to-end analytics product on a real, openly published transaction ledger — 1.07m invoice lines from a UK giftware wholesaler. Real data quality defects, seasonally-aligned experimental design, cross-validated models, a recommender that beats its baseline, and a decision engine that stops at a suggested action with its reasoning attached.
Demonstration · Predictive workflow
Healthcare readmission risk (synthetic)
Portfolio demonstration of feature design, validation, and operational scoring on synthetic discharge data — not a deployed clinical product.
Demonstration · LLM workflow
Research brief generator
Structured workflow for turning long-form research inputs into implementation-style briefs with a consistent schema.
Demonstration · Dashboard concept
Health financing KPI dashboard (synthetic)
Shiny concept for reimbursement lag, stockout risk, and facility priorities — illustrative data only.
