What I'm looking for

I want a role leading frontend architecture and performance at scale, collaborating cross‑functionally to drive measurable traffic, conversion, and reliability improvements while mentoring engineers.

I am a Principal Frontend Developer with 10+ years building high-performance, scalable web applications using React and Next.js. I focus on performance engineering, AI-assisted optimizations, and modular architectures that deliver measurable business outcomes.

I've led migrations and platform modernizations that produced sub‑1s load times, doubled organic traffic, and achieved 10× traffic growth for key product areas. I prioritize Core Web Vitals, caching/CDN strategies, and end‑to‑end profiling to reduce CPU/memory usage and improve stability.

I define frontend standards, create shared UI component libraries, and mentor engineers to increase development velocity and consistency across B2C and B2B products. I collaborate closely with product, design, mobile, backend, and SEO teams to deliver resilient, SEO‑friendly experiences.

My work includes automation and cost‑saving initiatives, accessibility sprints, and measurable conversion improvements—such as shrinking onboarding flows from 15s to 1s and boosting leads by 60%. I seek roles where I can lead architecture, performance, and cross‑functional delivery at scale.
