Notes from the work.

Notes on Agentic AI, architecture, product engineering, and the practical judgment required to build dependable software.

Three graded tiers of a single system rising in tolerance and consequence, with Persimmon marking only the tier permitted to act unaided

Rule, Recommend, Decide

Model selection comes up too early in most agent design reviews. Before choosing a provider, label every step in the production path with what it is actually allowed to do.

Not Every Workflow Needs an Agent

Assistant, workflow, agent is not a maturity model. Each is a different trade-off between predictability and adaptability, and the architectural question is where a process genuinely requires judgment.

Agentic Systems Are a Loop, Not a Model

Most conversations about Agentic AI start with the model. From a solution architect's point of view, that is the wrong starting point. The unit of design is the loop the model sits inside.

Four drafting stencils laid over a single plan, with one Persimmon stencil marking the review that changed it

Four Hats Before the First Line of Code

Claude Code will now produce a plan good enough to argue with. The practice that changed my results was reviewing that plan from several roles before letting anything be built.

AI Changed What a Rewrite Costs

A Salesforce integration I had been avoiding for a year had files past two thousand lines. Rewriting it with Cursor produced a four-fold performance gain, and the interesting part is which half of that work was mine.

From Figma to Tailwind Without the Translation Step

Paste the CSS, attach a screenshot, and Cursor produces the component. The interface work I used to schedule days for now takes an afternoon, and what remains is everything a picture cannot express.

Choosing Tamagui for Cross-Platform Work

A project this summer needed to ship on web and mobile without maintaining two design systems. Why I chose Tamagui, what its compiler actually buys you, and where I would still hesitate.

Migrating to shadcn/ui

Why I moved to shadcn/ui and how its open-code component approach changed the way I build interfaces.

Building an Administration Panel: Choosing the Stack

An admin panel has to balance user experience against developer experience. The stack I chose was React, TypeScript, Vite, and Tailwind CSS, and here is why each piece earned its place.

A place to start

Designing systems that can act.

Context, tools, orchestration, memory, evaluation, permissions, cost, reliability, and the decisions that should remain human.
