Top SchoolCharles Selvarajan is a Senior Staff UI Engineer based in the San Francisco Bay Area with 11+ years in production software and over a decade specializing in rich web UIs and web services. He blends deep front-end expertise in JavaScript frameworks (React, Next, Angular) with practical full‑stack experience in NodeJS and Ruby, and has led teams to deliver customer-focused products in e-commerce and payments.
