Things I've built
In June 2026, I’m leaving for a 3-year trip. The rough itinerary: Philadelphia → a summer camp in the USA (lifeguarding) → Seattle → Fiji → Australia on a Working Holiday Visa → New Zealand → SE Asia backpacking → Canada. Somewhere in there, I finish a data science project that’s been running on a Pi in my bedroom since 2025.
Final year CS dissertation exploring unsupervised segmentation of human activity recognition (HAR) time series data using six existing segmentation algorithms via the aeon Python library.
