On engineering leadership, value-based care, and the craft of building.

Memory for AI Agents is a filing system, not a file

Every AI agent wakes up with amnesia. This post details the Kelp codebase which runs two completely separate memory systems, one for the coding agent and one for the product. I argue that truely useful AI memory is a real subsystem with tiers, citations, expiry dates, and garbage collection. The hardest part isn’t recall; it’s knowing what to keep, what to supersede, and when to throw something out.

An introduction to building software for value-based care

This post argues that building successful software for value-based care (VBC) requires a shift in mindset: create a Customer Relationship Management (CRM) tool, not just a better Electronic Health Record (EHR). VBC realigns healthcare incentives around long-term patient outcomes, succeeding through proactive, relationship-based care rather than transactional services. Technology's role is to support this relationship by helping care teams orchestrate interventions effectively. The most valuable tools are often simple and pragmatic, focusing on the unique, core needs of the care model and enabling proactive management of patient health.

Learnings from building Kelp: Getting people the information they need when they need it is hard!

Reflections on pausing the contextual recommendation tool, Kelp, concluding that its goal—getting people the right information at the right time—is nearly impossible for a third-party app to achieve. The core problem is technical: without deep, OS-level access to user data and behavioral signals, recommendations remain mediocre. True contextual help must be built into the operating system itself. The key business takeaway was the need to solve a highly specific, paying use case for a narrow audience before attempting a broad, cross-platform solution.

Learning from a Hyper-Growth Startup

This reflection on leadership in a hyper-growth startup argues that self-management is the most crucial skill. Management in such a chaotic environment is inherently reactive and emotionally draining, not strategic and proactive. The key to effectiveness is to abandon "ruinous empathy"—the futile attempt to please everyone—and instead fiercely conserve personal energy for high-impact moments. This is achieved by accepting failure and tradeoffs as constant, communicating them transparently, and focusing on maximizing success in key areas rather than fighting every fire.

Slow looking from the same eye.
