Hardware, software, and the messy systems in between.
Building an E-Paper Digital Picture Frame
A low-power digital picture frame built on a Raspberry Pi and a 7.5" e-paper display. It auto-syncs photos from Google Drive, refreshes hourly, and boots straight into slideshow mode.
Launching the Allegris Seatmap
As Product Manager on the Gordian team, I helped lead the €2.5B Allegris seatmap rollout for Lufthansa — a major cabin overhaul focused on luxury and personalization.
Droneye: System Design
The system design of my year-long senior capstone: an autonomous, low-cost drone system that humanely diverts mammalian pests like squirrels and possums from backyards.
Field notes
Climbing trips, art, and life outside the terminal.
