NeuroNavAI safety · Accessibility · 2025

The stakes: Electric vehicles are quiet enough to erase the cue blind pedestrians rely on to cross safely.
My approach: Designed and built a voice-first system that sees the hazard and says so, on-device, in under half a second.
The outcome: Tested with 8 blind participants through the Iowa Department for the Blind.

100%Grasped the system in under 2 min

8/8Named silent EVs as their top risk

ParkShareTwo-sided marketplace · 2025 – present

The stakes: People were arriving two hours early just to secure a space.
My approach: Designed a two-sided marketplace around predictability instead of search.
The outcome: A comparative study showed a statistically significant improvement over the baseline.

6.23/7SEQ, 100% task completion

AnonVisionPrivacy · Computer vision · 2025 – present

The stakes: Journalists and researchers who blur faces can't risk one miss.
My approach: Designed a fail-safe architecture that hides every face by default and only reveals what's explicitly whitelisted.
The outcome: It runs entirely offline, on CPU, with nothing leaving the machine.

100%Offline, zero PII leaves the device

Carbon CompassBehavior change · Climate tech · 2025

The stakes: People care about their footprint but can't feel it. The consequence is decades away and the number is abstract.
My approach: Designed for temporal proximity, turning distant impact into a choice you can see at the moment you make it.
The outcome: A SUS score in the top 10% of evaluations.

83.75SUS, top 10% of evaluations

Pathic MRMixed reality · AI training · 2025

The stakes: Managers, doctors and HR staff get one shot at hard conversations and no safe place to rehearse.
My approach: Put you on the receiving end of your own words in mixed reality, with an AI counterpart that stays psychologically consistent.
The outcome: A working mixed-reality product, with a RAG architecture that keeps the AI character consistent.

Riches and BeyondEdTech platform · 2022 – 2024

The stakes: A live property-investing masterclass couldn't scale past the room it was taught in.
My approach: Turned it into a self-paced platform for working adults. Ran research in four countries, designed the interface, directed the video.
The outcome: 50,000+ paying learners in year one, on a SETA + QCTO accredited platform that still runs today.

If you're building something where trust, safety, or interaction actually matter, I'd like to hear about it.
