Designed advanced card-locking controls and a streamlined lost/stolen reporting flow for Central 1's banking platform — serving 295+ Canadian financial institutions. Took the feature from stakeholder discovery through pixel-perfect developer handoff in three weeks.

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.

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.

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.

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.

Designed and built three production AI agents for Omnia Consulting clients: a 24/7 FAQ bot and two RAG-powered coaching assistants grounded in 75 real session transcripts. Deployed on self-hosted infrastructure with no cloud dependency — Cloudflare tunnel, watchdog process, and documented recovery procedures. These are running systems, not demos.

Built a full automation stack for a coaching business client at Omnia Consulting: smart client onboarding that eliminates manual CRM entry, AI-powered meeting note processing that turns Zoom calls into structured Notion summaries, and a proactive reminder system that reduced missed appointments by 40%. Three interconnected systems built in Make.com — total admin overhead cut from 6+ hours/week to near zero.

Designed advanced in-vehicle HMI interaction prototypes for 42Dot, Hyundai's autonomous driving and urban mobility subsidiary. Work contributed to the concept and injection point of their Gleo AI project — the AI layer within their mobility platform. Built using ProtoPie Connect to bridge real hardware inputs with the prototype, enabling true-to-hardware demo experiences for executive and stakeholder review.

Designed interaction flows for Andel's pharmaceutical drug subscription platform — a mobile app handling medication management, recurring prescription flows, and health-critical user journeys. Navigated the high-stakes constraints of medical UX: clear affordances, trust signals at every confirmation step, and fail-safe flows for potentially irreversible actions.

Built high-fidelity interactive prototypes for enterprise clients at ProtoPie across fintech, civic tech, sports, media, and home services verticals. Work ranged from AI-integrated customer simulation for Thumbtack to video-heavy animation prototypes for MLB's app and TV redesign — each translating complex interaction briefs into testable, pixel-precise demos for C-suite and stakeholder review.

A collection of showcase prototypes built to demonstrate ProtoPie's interaction capabilities — including an official fintech bank app series with 3 published YouTube tutorials and 4 written articles (chapters 3–4 coming), an eVTOL aviation HMI demo based on the Joby S4, a CAR HMI dashboard using ProtoPie Connect for hardware integration, and a crypto trading app. These range from published educational content to conference-quality demos.

Wrote bespoke skill.md harness documents for enterprise clients in IoT and automotive — enabling designers and engineers to vibe-code custom ProtoPie Connect plugins without deep JavaScript knowledge. One client used an ESP32 microcontroller. Each document combines the ProtoPie Connect API spec, client hardware context, code constraints, and few-shot examples into a single AI-ready context file.
