Designed and built three full-stack applications end to end — architecture, backend, database, and UI: - SphereCore: a nutrition and hydration tracking system implementing peer-reviewed physiological models (Yamada et al. 2022) with real-time weather-adjusted calculations. - WienerCalc: migrated a legacy 1998 C-based nutritional calculation engine into an isomorphic TypeScript/Electron application with byte-for-byte parity testing. - WHS-WEB / ESTRATO: a custom narrative-publishing platform with a Markdown reading engine, CMS, and GSAP/Three.js interactive UI.
