What I'm looking for

I want to lead React/Next.js teams building high-performance, accessible products—owning architecture, Core Web Vitals, and developer experience—while mentoring engineers and shipping reliably with modern CI/CD and testing.

I’m a Senior Frontend Engineer with 8+ years of experience building production-grade React/Next.js applications at scale for US and Australian enterprise clients. I focus on TypeScript-first engineering, SOLID-aligned component design, and measurable improvements to Core Web Vitals.

I’ve led frontend teams of up to 10 engineers, owning architecture, performance, and developer experience. At ACL Digital (Client: PayPal), I engineered a TypeScript-first API integration layer that reduced frontend runtime errors by ~40%, designed schema-driven UI components used by 3 cross-functional teams, and used React Query patterns to eliminate race conditions and async failures under concurrency.

Across roles, I’ve also standardized shared abstractions (hooks and data-fetching), improved accessibility with WCAG 2.1, and mentored 5+ engineers in component-driven design and testing—so delivery is faster, safer, and easier to extend.
