I make small, focused apps: a hex strategy game, two tools for learning Spanish and passing Spain’s citizenship exam, and an offline reader for classic game walkthroughs. These are the four I’m building right now.
Grow your kingdom. Break theirs at the seams.
Dominex is a single-player strategy game where every hex earns money and every soldier costs it. Expand your kingdom, outsmart five AI rivals, and cut their territory apart to bankrupt their armies, all while keeping your own economy alive. Inspired by the classic Slay, it brings approachable rules and deep tactical choices to your browser, iPhone, and iPad.
Understand the CCSE in English. Remember it in Spanish.
CCSE English helps English speakers prepare for Spain’s citizenship knowledge exam with clear English explanations, spaced repetition, and realistic Spanish mock exams. It turns unfamiliar material into lasting knowledge, so learners walk into the exam feeling prepared. I built it after preparing for the CCSE myself.
Old-school game guides, beautifully readable on iPhone.
Retro Game Guides turns classic game walkthroughs into a clean, searchable offline library on your iPhone. Bring the guides you already trust or follow an included original Standard Edition, with readable text, clickable contents, bookmarks, and saved progress so you can pick up exactly where you left off. No ads, accounts, or subscriptions.
Stop freezing on Spanish verbs.
Spanish Verb Master combines spaced repetition with instant, letter-by-letter feedback, using your hesitations and corrections to find what needs more practice. Short, focused sessions build accuracy, confidence, and lasting recall.
I started Lullabot in 2006 and sold it to its employees through an ESOP in 2021. Along the way, I was voted one of the best CEOs in the US in 2018.
I co-wrote Pro Drupal Development and later Go Prompt Yourself!, a guide to metaprompting ChatGPT.
