this is me!

Hi, I'm Dennis!

I'm a software engineer. This summer I was at Ramp as a SWE intern in NYC. I'm also building Physical Reasoning, training data and infrastructure for world models.

Before that, I was at Shopify working on the retail kernel, and at Infinite Investment Systems building NLP and data platform infrastructure.

I study Math & CS at Toronto Metropolitan University, did an exchange at Nanyang Technological University in Singapore, and compete on the university's ICPC team.
