I'm Leo Walker — an AI engineer with a Ranger's instinct for execution and a data scientist's eye for signal. I've been building with NLP since 2016. Today I turn hard, ambiguous problems into practical systems teams can actually move on — currently in clinical AI at KaiCare.ai.
The through-line
Different chapters, one habit: take something complex and make it move. Here's the arc — and what each part taught me about doing the work.
Where I learned that standards are not negotiable and that a plan only matters if it survives contact. Precision, ownership, and calm under load — the operating habits everything since has been built on.
I followed the data — into energy and venture capital — and got hooked on language models before they were fashionable. The lesson: the hard part is rarely the model, it's framing the right question and trusting the signal.
Formalized the pattern recognition. Statistics, ML, and the discipline to tell a real result from a comfortable one. I came out caring less about novelty and more about systems that hold up.
Agents, LLM composition, evaluation, and the unglamorous plumbing that makes them dependable. Good AI engineering is mostly judgment about what to automate, what to verify, and what to leave to a human.
Remote patient monitoring and care-management systems where the stakes are real. It's the current proving ground for the same principle: turn messy complexity into something a team can actually move on.
