What I'm looking for

I'm looking to own system design, product architecture, platform foundations, and AI engineering for multi-tenant SaaS or fintech products, while mentoring engineers and raising quality through strong developer experience, automation, and shared engineering ownership.

At FundThrough, I led a zero-downtime migration to modular V2 packages, reducing bundle size from 800kB to 300kB, and built an LLM document-review pipeline that reduced servicing cost by 20%. I also architected a widget platform serving 10,000+ daily users and delivered onboarding experiences that tripled downstream conversion.

I've built platform foundations and multi-tenant products from zero at Rocketlane, delivered enterprise integrations and BI workflows at HappyFox, and led teams through architecture, hiring, mentoring, quality engineering, and AI-assisted development. I contribute to Storybook, TanStack Query, and the Ember ecosystem, lead development at TorontoJS, and speak at JavaScript and React communities.
