I am a Senior UI Engineer currently Walmart Global Tech, previously Lowe's and Infosys. Most engineers fail product interviews not because of basic syntax, but because they struggle under real-world constraints: main-thread performance, memory leaks, deep DOM architecture, and state synchronization. Having navigated the exact trajectory from service-firm maintenance to Tier-1 product tech, I offer targeted, zero-fluff sessions covering: • Live Tier-1 Machine Coding execution & clean patterns • Senior Frontend Architecture & Web Vitals forensics • Service-to-Product career transitions & resume positioning
