Who I am
What I do
I'm a Computer Science student at the University of British Columbia in Vancouver, working mostly on the parts of a system nobody sees, backend services, internal tools, and the data plumbing underneath them.
Earlier this year I was a backend developer at LintelAI, building REST APIs and the services behind them. I'm looking for a Summer 2027 software engineering internship where the work is server-side and the systems are big enough to be interesting.
