Learn. Build. Explain.

Always learning. Sometimes building. Often explaining.

Hi, I’m Kush 👋

Technical Product Manager · 17+ years in tech · 5+ years in product · leading an enterprise AI platform

I lead an enterprise AI platform by day and build my own AI products after hours. This blog is my learning, in public. Everything starts with learning: some of it I build with, some of it I explain in plain words, so product people and non-technical folks in tech can follow AI and product concepts without the jargon.

Learn Tech Digest Digital Dhaba every Thursday: what's happening in AI and tech, and why it matters. Learn + Build Build Log Products I'm building in public: the decisions, the mistakes and the lessons. Learn + Explain Concept Breakdown Comic-style breakdowns of ML, GenAI, cloud and product concepts. No jargon. Learn + Explain Learning Notes My own notes on papers, essays and talks I've read, in plain words.
