May 2026 – Present
- Architected and shipped an AI-adaptive learning engine in Flutter/Dart using Bayesian Knowledge Tracing, modeling each student's latent knowledge state in real time to dynamically adjust explanation depth, code visibility, and hints across lessons.
- Engineered a multi-signal delivery layer combining 4 inputs (quiz performance, time-on-page, hint reliance, and per-page mistake counts) into a continuous difficulty score, improving adaptation accuracy over a quiz-only baseline.
- Designed the persistence layer on Supabase (Postgres) to carry adaptive state across sessions and recover partial signal on mid-lesson exits, eliminating dropped engagement data that previously reset on every navigation.
