What I'm looking for

I’m looking to lead frontend delivery for secure, high-performance products, collaborating with product/design/backend/security/compliance. I want to keep strengthening modular architecture, design systems, automated testing, and production-ready quality.

I’m a Senior Frontend Engineer with 9+ years of experience building secure, scalable web applications across RegTech, fintech, e-commerce, and enterprise SaaS in Canada and Europe. I’ve grown from implementing responsive consumer-finance interfaces to owning modular frontend architecture, complex enterprise workflows, and engineering quality.

I specialize in React and TypeScript, creating maintainable UI with design systems, reusable patterns, and performance-focused delivery. Across roles at Fenergo, Zalando, Shopify, and MOGO, I’ve led frontend work end-to-end—integrating API-first services and role-based access controls, shipping automated testing with Jest/RTL/Cypress/Playwright, improving Core Web Vitals, and mentoring engineers through planning to production.
