Hey, I'm David.

I went to school for nursing. Good career on paper. Stable, respected, the kind of path nobody tells you to question.

I questioned it anyway.

Not because the work didn't matter. Nursing matters enormously, and the people I worked beside at the Montreal Children's Hospital are still some of the best I've known. I questioned it because I'd never actually chosen it. I was running on defaults: other people's expectations, a life script I'd inherited without ever reading the fine print. The problem was never my circumstances. For years, the obstacle was me.

So I rebuilt from the operating system up

The pivot didn't take me out of healthcare. It took me deeper in, on my own terms: from the bedside into patient services and operations, then digital products, then innovation. Each step chosen, not inherited. Alongside it: new habits installed on purpose, money that bought options instead of stuff. I taught myself to build, started shipping projects, and eventually helped my parents retire, which is still the achievement I'm proudest of.

Along the way I went deep into the FIRE world, saving aggressively, optimizing everything. Then I read Die With Zero and realized I'd over-corrected. I was so busy building the future that I'd stopped living in the present. Now I aim for balance: build wealth, and actually use it. (I even built a calculator to keep myself honest about it.)

Where I am now

By day, I lead digital health innovation at a global pharmaceutical company in Montreal. I came up through seven years of patient services and operations, building the data pipelines and automations that removed our worst friction, and in the last year I went fully AI-default: I ship AI and automation products, build internal apps with AI-assisted coding, and teach colleagues to work the same way. If you found me through LinkedIn, that's the professional half of this story.

The rest of the time, I'm building more in a single weekend than I used to ship in a quarter, because AI turned out to be the most absurd accelerant I've ever touched. The latest thing I vibe-coded: ApplAI, a job-application copilot that tailors my CV and cover letter from my real history, then literally fills out and submits the application itself. My only job is to review and confirm. I'll say this clearly though, because it's the whole point: AI is the accelerant, not the hero. The e-bike still needs you to pedal. It multiplies whatever you bring to it. Bring shallow thinking, you get faster mediocrity. The human is still the one who decides what's worth building.

What I write about

Everything here lives under three pillars, with AI threaded through all of them:
