About

I'm a senior software engineer based in Toronto. Over eleven years I've worked at JPMorgan, Scotiabank, AWS, and Dropbox — each time moving toward a harder class of problem.

My background spans financial compliance systems, cloud data infrastructure, and privacy engineering. I don't specialize by domain. I specialize in the kind of work where correctness, security, and scale aren't optional — where the system failing has a cost you can measure in dollars, data breaches, or regulatory action.

I write here when I have something to say that is specific enough to be useful. Most of it comes from building things, breaking things, and watching other people build and break things in high-stakes environments. I'm not a consultant, and this is not a content calendar.
