Field notes on AI, systems, and product engineering
Long-form field notes with reader promises, practical workflows, and honest tradeoffs — written for engineers who want signal, not hype. Claims are labeled when they are judgment, and linked when they are facts.
You will understand how Razorpay tokenized 4 billion payment transactions, how Vulcan unifies fragmented routing, fraud, risk, and checkout personalization into a single foundation model, and the systems engineering behind financial transformers.
You will understand why Cursor moved down the developer stack into code hosting, how agent-native repositories differ from legacy Git remotes, and how Origin unifies IDE, agents, PRs, CI, and Vercel deployments into one platform.
You will leave with a clear split between the model (Grok 4.5) and the harness (Grok Build), plus a routing checklist for when each belongs in your agent loop.
You will see what developers should expose to Siri AI: entities, schemas, confirmations, and calm automations—grounded in Apple’s public WWDC26 materials, not invented APIs.
You will get a practical model for turning source-grounded AI into a research workflow—without treating new agent features as a license to skip primary reading.
You will leave with a clear map for splitting AI work between browser tools, local helpers, and cloud agents—without treating the keynote as a shipping checklist.
