about me

hi! i'm leon, i live in stockholm with my sambo. i've recently graduated with a master's degree in cs. i'm big into ml, research, and coding. i enjoy food eating, food making, traveling and working out.


i've got a background in software engineering but as of last year i'm a research engineer. i'm interested in: foundational models, policy learning, medical ai, and reasoning agents. if you're curious about my current fixations, skim the blog.

i like making things

healthy mix of research, experiments, and scratch projects.

  • alphax, scalable + fast alphazero in jax. facilitates spmd, simd, jit-composition etc
  • exploring limitations of llm-as-a-judge
  • llmcontext (fork of original), a context window pressure tester of open llms
  • a framework for super-resolution of clinical 4d flow mri. paper.
  • alphafour , minimal alphazero for connect four in pure pytorch
