Sygil, Sivra, and Osmo are on the App Store today — built by hand, by one person, while running a construction business across New York.
What started as proof is ready to grow. I'm opening Devello Studios to a small group of investors, partners, and operators who recognize a patient builder and want to stay close to the work. You don't have to come from tech to see what this is.

Where I write down what I'm thinking, building, noticing, and questioning along the way.
This started as curiosity. The same instinct that pulled me into building things eventually asked a harder question: what does it take to lead them? Courage, I have come to understand, is not the absence of fear. It is being scared and doing the thing anyway.
Read articleNobody writes down the real P&L of a software studio. API bills that creep, Apple review cycles, the gravity of three codebases, verification interviews, infrastructure that layers silently. The sticker price of "it just works" is paid in places you do not expect.
We overestimate what AI can do in a month and wildly underestimate what it can do in a year. A look at the actual slope — training cost per capability, inference cost, benchmark jumps — and what that means if you are building on top of it.
How the unique ability of humans to craft and use tools has helped change the course of history, from primitive implements to digital technologies.
The introduction of digital intelligence has paved the way for learning and rapid implementation of ideas, transforming how we approach creative problem-solving and innovation in the modern world.
Exploring the relationship between creative freedom and the mental constraints such freedom introduces, revealing how boundaries can paradoxically enhance artistic expression.
