Where bits emerge into systems.
I'm Kristan 'Krispy' Uccello — engineer, architect, and author. I write about building intelligent systems with Rust, functional programming, and large language models. This is my corner of the internet.

Why Rust Is the Right Language for LLM Inference
Python dominates ML tooling, but when it comes to inference performance, Rust's ownership model and zero-cost abstractions offer something Python simply cannot.
Monads Are Not Burritos: A Practical Introduction
Every monad tutorial reaches for a food metaphor. Let's skip the analogies and look at what monads actually do in code — specifically in Rust.
Emergence in Large Language Models: What It Actually Means
Researchers use 'emergence' loosely. Let's be precise about what emerges in LLMs, when, and what the implications are for building with them.
Featured Projects
LLM Inference Engine in Rust
activeA from-scratch inference runtime for transformer-based language models, written in Rust with a focus on memory efficiency and zero-copy tensor operations.
Functional Combinator Library
activeA Rust library exploring algebraic data types, monadic composition, and parser combinators — drawing inspiration from Haskell's ecosystem.
Emergent Agents
wipAn experimental multi-agent framework where LLM agents coordinate through message-passing and shared state without a central orchestrator.
The Book
Work in Progress
LLMs, Rust & Functional Programming
A practical guide to building intelligent systems with Rust — from first principles of functional programming through modern transformer architecture and production inference. No Python. No magic.
