About Me
#

Early experience I began programming at the age of 11 and have been hooked ever since. I got my first job at 16.

Education During my final high school years, I studied at university early. When at KTH, I worked as a Teaching Assistant and Research Assistant while still an undergraduate student. Even teaching my student peers as a TA, while also taking the same classes myself.

Hobbies I like to spend time with family and friends, play online games, work out at the gym, participate in track and field athletics, play the cello, and read books and research papers.
I’m deep-diving into Programming Language Design, Type Theory, and Compiler Design.

Personality I am a creative problem solver who enjoys new challenges and learning opportunities. I try to be considerate, kind, attentive, thorough, curious, and generally open-minded.

Highlights

I have participated in various competitive programming contests, hackathons, startups, and CTF competitions playing in the Swedish National Hacking Team and the RoyalRoppers CTF teams.

Creator, Programming Languages: Designed and implemented interpreters and compilers for Lento, Web X, and mini, among others.
Compiler Team, Miking: A framework for constructing efficient domain-specific languages.
Member, ACM SIGPLAN: Association for Computing Machinery's Special Interest Group on Programming Languages.
Board member, KTH Stacken Computer Club: Attended weekly meetups and presented on programming topics.
Organizer, Undutmaning CTF 23, 24, 25: Technical project manager for the website, infrastructure, and challenges.
Member, RoyalRoppers Team: Expertise in reverse engineering, web, network, binary exploitation, cryptography, and more.
