Machine Learning Engineer · Systems Builder · Reality Modeling
I build real systems under constraint.
I've shipped forecasting models for Peru's Central Bank, built and deployed full-stack commerce platforms, and created developer tooling in Rust to support real research and production work. I work across the stack — modeling, infrastructure, and deployment.
Why I Built These Tools
Working seriously with AI — on real research, real forecasting, real codebases — exposed a gap nobody was filling. Context gets lost between sessions. Projects fragment. The model forgets what you built last week, and so, eventually, do you.
I didn't want wrappers around ChatGPT. I wanted tools that treated the problem structurally: flatten a codebase into something injectable, control what a conversation remembers, give unstructured data a shape that survives without a database schema.
These aren't side projects. They're the infrastructure I actually use — for my research, my consulting work, and the book I'm currently writing.
Interactive Systems
Production-grade tooling built to support real research, forecasting, and engineering workflows. Designed from friction, not theory.
Kodomata World
An emergent automata environment built from minimal local rules. Designed to study how simple constraint systems produce large-scale collective structure.
Wormhole Chess
A non-Euclidean chess engine with paradoxical geometry and explicit spatial mapping. Built to explore constraint modeling and engineered rule systems beyond standard board abstractions.
The Fractal Prince
A recursive platformer built and shipped end-to-end. Designed as an experiment in constrained traversal and self-referential level structure.
Developer Infrastructure
Tools I made because the existing options were frustrating, fragile, or just not built for serious use. All of them I still use.
Yggdrasil
Flattens an entire codebase into a structured markdown artifact for LLM ingestion. Used in real research and development workflows to reduce context fragmentation.
Membrane
A structured YAML-based knowledge system for managing evolving research artifacts without rigid schema constraints.
FUR
Conversation control infrastructure for language models. Tracks interaction state and preserves context integrity across sessions.
Elaine
Deterministic LaTeX bibliography generation built to avoid failure-prone citation managers in research environments.
How I Actually Work
Not principles in the abstract. Things I've learned the hard way.
The model is the bottleneck
I spent months forecasting GDP with state-of-the-art ML tools. The math was rarely the problem. How you frame the question — what variables you include, how you define the search space — determines everything downstream. My research came directly out of that frustration.
Tools should survive real pressure
I built Yggdrasil because I needed it mid-project, not because it was a clean idea. The same goes for FUR and Membrane. Friction is a better design brief than a feature list.
Rust is a choice, not a flex
I write tools in Rust because I want them to be fast, stable, and honest about what they do. Python is where I explore. Rust is where I commit.
Clarity compounds
Teaching computer science to undergraduates taught me more about my own understanding than most research did. If you can't explain a system simply, you don't control it yet.
