Ranga’s working notebook on learning, building, and moving toward frontier AI research.

hey, I’m Ranga. I finished my master’s in Applied Data Science at San Jose State in May 2026. I’ve worked across apps, systems, LLMs, and generative AI, but I want to go deeper into mathematics, papers, model training, and the core research problems that frontier labs work on. this is where I learn those things, build working prototypes, revise what I thought I understood, and keep TL;DR-first notes for anyone trying to take a similar path.
