waste data clean enough to make decisions with.

elinnov's clients report waste by site, and every site reported it differently. i built the esg dashboard that cleaned those reports into one picture a sustainability team could act on.

python · pandas · react · charts

problem: units, categories, and dates varied by site and by month, so totals were either wrong or took a day of hand-fixing to get right.
what i built: cleaning rules that map each site's reports onto one set of categories and units, and a dashboard that shows trends by site and by waste stream, with the questionable rows flagged instead of hidden.
what i took from it: most of a data product is the cleaning nobody sees.
