What I'm looking for

I'm looking to build scalable, high-performance frontend platforms where I can shape architecture, design systems, accessibility, and engineering standards while mentoring teams and delivering complex product workflows.

I've built frontend platforms for Starbucks, theScore Bet, Varicent, The Home Depot Canada, and Exchange Solutions, delivering scalable web applications for complex planning, sportsbook, and SaaS workflows.

At Starbucks, I built the product assortment planning frontend used by 25,000+ locations across the US and Canada. I established a React, TypeScript, Vite, and Node.js platform adopted by multiple teams, delivered 20+ features, and increased test coverage from 35% to 65%+ through Cypress, TDD, and automated quality gates.

I enjoy shaping frontend architecture, design systems, performance-sensitive interfaces, and shared engineering practices. I've mentored 20+ frontend engineers and use AI-assisted workflows, system design, and accessible component development to help teams deliver with confidence.

I’ve also taken to AI Engineering, learning about the core technology but also how to fine-tune solutions to every client’s needs.
