Panels Panels is a dual-map comparison tool for exploring GSI (Japan Geospatial Information Authority) tile layers, built as an internal tool and later rebuilt as an open project. Compare historical aerial imagery, topographic maps, and land use layers across time in either a side-by-side or opacity-blended overlay view, with synchronized pan/zoom across panels.
Supergeografi Supergeografi was an Indonesian-language geography learning platform I built during my undergraduate years after competing in the national Science Olympiad (OSN Geografi) and realizing most students lacked access to the English-language resources I had relied on. Built on Gatsby JS, Contentful, and Algolia search, the site compiled structured articles and practice sets from OSN, iGeo, and USGC archives, growing to 30,000 monthly views. The project has since been discontinued and the domain is no longer under my control.
