Case studies from current and recent engagements. Each names the problem, the constraint that made it hard, what I owned, and what was delivered.
A geospatial seasonality upgrade for malaria models
Rebuilding malaria seasonality from one curve per country into an admin1-resolution, mechanism-aware emergence surface — water-balance and species-kernel models, calibrated and handed off to OpenMalaria.

A Windows-only modeling pipeline the portfolio owner could run from their Mac
A Spectrum GOALS pipeline across 55 countries where the analysis and launch layer ran on the owner’s Mac and the heavy compute ran on a self-built Windows box over SSH — with Dropbox as a shared filesystem and results synced back.
