hi! i'm jake.

i like figuring out how things work, and building them myself helps me understand them better.

lately i've been working on llm agents, learned simulators, and making ml inference faster.

i'm also interested in high performance computing, especially how memory access and parallelism affect performance when i'm writing kernels.

i love optimizing things and seeing how far i can push them. i'm also interested in how complex systems scale without becoming a pain to maintain.

computer engineering and computer science, math minor @ northeastern, on a ujima global leaders scholarship.
