Making Complex Systems Easier to See.
I create sharp lenses for looking into real-world places, systems, and events through spatial thinking, public data, and interactive maps.
What I build
Interactive maps
Custom web maps for transit, events, travel, heritage, and public information.
Spatial data tools
Turning fragmented public data into searchable, visual, user-friendly products.
Place-based products
Tools and stories that help people understand cities, places, routes, and everyday systems.
Featured works
EVENT MAPPING · WORLD CUP '26
Cup26Map
An independent spatial guide that connects matches, host cities, venues, time zones, teams, and travel routes in one interactive map.
REAL-TIME TRANSIT · TORONTO
LiveBus
A mobile-friendly web map that shows live TTC bus and streetcar locations together with stop arrival times, helping riders cross-check ETAs against actual vehicle movement.
About me
I’m a Toronto-based maker working on maps, public information, local culture, and how people experience places.
I pay attention to the systems behind everyday life: transit, neighbourhoods, heritage, tourism, public data, and the details people often miss.
My background in spatial design and GIS shapes how I think: visually, structurally, and with a strong interest in deep research. I like tracing a problem back to its context before deciding what should be built.
If your project involves places, maps, public information, or local experience, I’m open to thoughtful conversations and selected collaborations.
