When a user asks a question, the system performs a “database fetch” on demand, pulling context just in time to generate an answer. We haven’t reinvented software; we\u2019ve just replaced the mouse click with a prompt, keeping the same brittle, pull-based architecture underneath."},{"title":"How LLMs Read?","link":"https:\/\/gen-ai.fyi\/posts\/2026-01-16-how-llms-read\/","pubDate":"Fri, 16 Jan 2026 00:00:00 +0000","guid":"https:\/\/gen-ai.fyi\/posts\/2026-01-16-how-llms-read\/","description":"Before an LLM can 'think', it must 'read'.

At Intuit, I am driving the vision for Agent Foundry, an internal platform designed to bridge the gap between Design and Engineering. I focus on solving the “Chat UX vacuum” by building environments that allow teams to prototype ReAct agents and MCP servers, enabling “shift-left” vibe-checks and evaluation of agentic behaviors before a single line of production code is written.\nI also work on Data Strategy, specifically solving the “Cold Start” problem for business agents."}]}}
