What I'm looking for

I want to build and scale frontend systems end-to-end—delivering measurable Core Web Vitals wins, reliable testing, and maintainable architecture in teams that value learning, clean code, and real impact.

I’m a Senior Software Engineer and frontend developer who loves turning ideas into clean, thoughtful code while tackling hard challenges head-on. At Cimpress, I built and scaled the Design Assistant real-time design engine, improving CWV and Core Web Vitals—boosting CWV scores and significantly improving LCP and INP across desktop and mobile.

I’ve also migrated the Design Assistant from Next.js to a proprietary SSR framework to improve performance through caching and code restructuring. I work end-to-end with observability (NewRelic), testing (Cypress, Vitest, K6), and CI/CD (GitLab), and I’ve migrated core services to AWS while creating architectural documentation for future updates.
