3-Sided Volunteer Matching Platform

Led design of a web platform connecting skilled volunteers, nonprofits, and corporate clients for pro-bono collaboration. Took the product from research through shipped beta in four months — covering three distinct user portals, a full design system, and 26 usability test participants across all user groups.

Finance Calculators Visual Re-Vamp

Redesigned seven financial calculators — Mortgage, Retirement, Education Savings, RRIF, TFSA, and Foreign Exchange — used across 300+ Canadian credit unions. Extended Central 1's Forge 2.0 design system with new calculator-specific components, moving from a dated dark-themed UI to a clean, modern, accessible experience.

AI Reliability Architecture

A structured research program evaluating AI coding tools across five prompting strategies using SUS, UES-SF, and UEQ evaluation frameworks — running AI self-evaluation and human evaluation in parallel. The key finding: AI inflates its own output quality by up to 30 points versus human scoring. Synthesized into a practical framework defining the instruction, constraint, and feedback layers required before AI outputs can be safely delegated to end users.

ProtoPie Kinetics

Led ProtoPie Kinetics end-to-end as Product Manager and designer — defining scope, assembling a team of 5, managing weekly delivery cadence, coordinating sign-offs across QA, Legal, Security, and Marketing, and shipping a live product in 3 weeks. Kinetics maps physical object motion (attaching sensors to real objects like a tennis racket, plane model, or toy) to ProtoPie prototype interactions in real time. Made the deprecation call a month later when adoption data didn't support continued investment.

eVTOL Aviation — Joby S4 Cockpit HMI

Designed and prototyped cockpit interface interactions for an eVTOL aircraft built around the Joby S4 — a real-world electric air taxi in active development. Referenced Joby's flight control mapping documentation and Microsoft FlightFX integration to keep the interaction design grounded in real aviation UX constraints rather than generic UI patterns.
