Hi, I'm Hari

Product-focused Frontend Architect with 10+ years of experience shipping 0-to-1 products at Shopify and AWS.

I specialize in bridging complex backend telemetry — like anomaly detection and IoT data — into intuitive, high-performance UI using Server-Driven UI (SDUI) and scalable design systems. Currently exploring AI-native workflows and agentic UI patterns.

What I'm Doing

  • Senior Frontend Engineer at Shopify — building high-integrity event tracking, Dynamic Creative Optimization, and pioneering "Contextual UI" with Model Context Protocols (MCP)
  • Writing at Near the Singularity — my blog on frontend architecture, AI, and building software near the singularity
  • Building open-source tools and side projects in the AI + frontend space
