Building software, teams, and ideas

15+ years building software, 5+ leading teams. Still writing code daily.

I share what I learn about software and leadership, and build websites for businesses and independent professionals.

Start with what you need

Write better software TDD, refactoring, design, and the habits that keep code changeable. Lead engineering teams Trust, feedback, priorities, and the human side of technical work. Work with AI agents Context, tools, and the decisions that still need a human. Understand Bitcoin The protocol, sound money, privacy, and the Lightning Network.

Ownership means following a problem through to a working solution. It takes initiative, support, and the authority to make decisions.

AI agents ship faster than you can review. The answer isn't speeding up. It's choosing where your attention actually matters.

Working in the open lets people help while the work is still shapeable. The real skill is pushing the right signal to the right room.

Let people act, let goods pass. No planner knows what the market knows, and freedom, not control, should be the default.

(ns app)
(defn greet [name]
(str "Hello, " name "!"))

Functional programming meets PHP. Write expressive, immutable code with macros, pattern matching, and a REPL.

function test_sum() {
assert_equals 4 "$(sum 2 2)"
}

Write tests for your bash scripts with a simple, expressive syntax. Assertions, mocking, snapshots, and more.
