I am a Senior UI Engineer at enterprise scale (Ex-Infosys, Ex-Lowe's, currently Walmart Global Tech). This channel provides production-grade architectural deep dives:

• Core Web Vitals & Telemetry forensics (INP, LCP, CLS via Chrome Profiler)
• Enterprise Machine Coding interview patterns built from scratch
• Runtime memory diagnostics & DOM virtualization
• Service-to-Product career transition blueprints
