Kia ora, tervetuloa, & tere.

I'm Oscar, a software engineer from New Zealand.

I've worked at AI-based startups (twice), a regtech scale-up, and a big cinema software multinational, among other things. I'm most experienced with modern fullstack Javascript/Typescript web tooling and C# but I like to try new technologies.

I'm currently freelancing (and studying the Finnish language) from Tallinn, Estonia. I'm actively looking for interesting and challenging projects to work on. Drop me a line.

Outside of work, I'm passionate about regulatory reform to create more liveable cities.
