About Lucía
Lucía Morales built and maintains the benchmark dataset at the heart of The Calorie Guardian: 1,400 meals and dishes drawn from 24 countries, tested against the apps with 134,000 photos and dish descriptions, each item carrying a reference weight and a verified nutrition breakdown. She holds an MS in Data Science and previously worked on image-recognition evaluation pipelines in Santiago.
Her job is to make the testing boring and repeatable. Every app is fed the same photos, the same barcodes, and the same free-text descriptions, and every result is logged so a second analyst can re-run it. She reports accuracy as error bands, not single hero numbers.
Lucía also curates the international and mixed-dish portion of the dataset — the messy, real-world meals that expose the gap between a demo and a daily driver.
What Lucía tests Owns the 1,400-dish dataset and runs the data-accuracy, international-food, and barcode benchmarks.
