Man in suit

Hi, I am Philip Elias Fleischer

Computer Science student at the University of Oslo, focused on systems programming, networking, and backend development. I enjoy building reliable, low-level and performance-oriented software, while also working across the stack to deliver complete, maintainable applications.

About me

Profile

I am a Computer Science student at the University of Oslo (BSc expected Spring 2026), focused on systems programming, networking, and backend development. I enjoy building “under the hood” software—things like protocols, reliable communication, and performance-focused code—while also caring about clean architecture and maintainable solutions.

Recently, I have worked on projects such as a custom network stack in C (MIP daemon + routing) and a weather application with mapping and wind visualization. I like projects where I can combine low-level understanding with practical product thinking, and I am currently expanding into full-stack development (TypeScript/React + Node + databases) to ship complete applications.

I am looking for junior roles and projects where I can contribute, learn fast, and grow into a strong engineer in systems, networking, and modern web/backend.
