$ so, who is this guy?
I write software. The business behind it doesn't matter to me — what matters is that the system holds its shape under load and does exactly what it's supposed to. Java, Spring Boot/WebFlux, microservices, and a bias toward architecture that survives contact with production.
I own systems end-to-end: service boundaries and data flow when things are calm, live incident response when they're not. Hand me an unfamiliar problem in a stack I've never touched and the answer's the same — I'll figure out how it works and make it do what it needs to do.
I learn fast and I'm not precious about which codebase I'm dropped into. Lately I lean on AI assistants and prompt engineering to move faster — and I audit every script and package before it touches a repo.

One of two backend engineers on the University of Toronto Press site redesign (utorontopress.com) — a Literatum flagship client at Wiley. Worked directly with the frontend team to integrate new UI components into the existing backend as the design rolled out.

$ learning is the actual hobby
500+
courses & books, tech and leadership, in no particular order
Shipping code is the job. Reading about how to do it better is the hobby — I've gone through 500+ courses and books, on everything from distributed systems to leadership, mostly at random, mostly at night.
Not all of it is directly useful. Some of it changes how I write code six months later without me noticing at the time. That's the actual point.

$ still scrolling? let's just talk.
I reply faster than most CI pipelines. Bring a hard backend problem, a payment system that keeps waking you up, or just a good conversation about distributed systems.
