Designed the end-to-end interface for the Philippines' national nutrition surveillance platform, built with the National Nutrition Council. Cited in an official implementation commitment.
Fragmented reporting, one system
Nutrition data in the Philippines was gathered locally and reported upward through channels that did not agree with each other. NNIS was built with the National Nutrition Council to make that one system: local and regional offices record and validate indicators, and the data becomes visible in something close to real time rather than months later.
I designed the whole interface, visual identity through to the user flows, as Frontend Design Engineer at DigiPH.
Designing for two audiences at once
The same system serves a barangay health worker entering figures and a national policymaker reading trends. Those are opposite design problems. Entry screens need to be fast, forgiving and usable on whatever device is to hand; the analytics views need to make a national picture legible without flattening it into something misleading.
The system now underpins nutrition surveillance nationally and is named in an official implementation commitment. It is the largest-scale thing I have worked on, and the one where a bad interface decision costs the most.
