What I'm looking for

I seek senior engineering roles focused on scalable web/mobile platforms, performance, observability, and mentorship in collaborative, delivery-focused teams.

I am a Senior Software Engineer with 8+ years building production-scale web and mobile systems across SaaS, content platforms, and consumer applications. I specialize in frontend architecture with React, Vue and Next.js, and build resilient backends using Node.js, Python and GraphQL.

At Squarespace I architected high-traffic frontend systems for 1.5M+ monthly users, led a migration to Next.js SSR/ISR, improved render performance and SEO, and introduced Python automation and CI/CD practices that sped deployments and reduced manual review effort.

I am pragmatic about performance, observability, and accessibility, mentor mid-level engineers, and enjoy modernizing legacy systems, optimizing delivery pipelines, and shipping reliable cross-platform experiences.
