Software developer turned AI researcher. Four years building Somalia's first Electronic Health Record system—serving 100+ clinics nationwide. Now studying transformers from first principles.
The kind of engineer who needs to understand what's underneath. Not just use the tools—build the intuition for why they work.
Research Log
The Mental Maps That Made ML Click
Frozen functions, two timelines, loss as a thermometer, backprop as blame assignment. The pictures underneath the function calls.
Seven Chapters Deep: What Linear Algebra Looks Like From the Inside
Seven chapters of Strang. Nullspaces, eigenvalues, SVD—computed by hand. What you see in transformers after building the math underneath.
What Doing Linear Algebra by Hand Showed Me About Transformers
LU decomposition, column spaces, and the dot product—computed by hand, chapter by chapter. What you start seeing in transformers when you do the mathematics yourself instead of reading about it.
The Journey from Software Developer to AI Researcher
A personal chronicle of the path from building production systems to understanding what happens inside a transformer. Vectors, Word2Vec, attention mechanisms, and the mathematics underneath it all.
