Hi, I'm Christopher

Senior ML engineer with seven years of shipping production AI in education and defense. I write interactive explainers for the technical foundations behind modern computing — machine learning, statistics, and the systems beneath them.

I'm applying to the Doctor of Health Informatics program at UTHealth McWilliams for August 2027, and I'm interested in the intersection of large language models and clinical data. Open to senior ML / applied-research roles in parallel — see /now for what I'm actively working on, or get in touch below.

Speaking

I haven't given a public talk yet — but I'd like to. If you organize a meetup, conference, or seminar, here are talks I'm ready to deliver.

Talks I'd love to give

Teaching CS Fundamentals with Interactive Simulations

Most explanations of how a CPU works either stop at handwavy block diagrams or jump straight to assembly. I'll walk through how I built the interactive transistor and logic-gate simulators behind my 'Silicon to Systems' series, what makes a technical explainer click vs. fall flat, and the React/Canvas patterns I keep reaching for. Target audience: anyone who teaches CS, writes technical docs, or wants to see what's possible with a static site and good intentions.

30-40 min•Engineers, educators, technical writers

Why We Migrated Our LLM Orchestration POC from Go to Rust

A field report from rebuilding a multi-modal LLM content pipeline (slideshows, podcasts, quizzes) from a working Go POC into production Rust. What we found, what we'd do differently, and where Rust paid for itself vs. where it didn't. Frank about the costs — Rust isn't free.

30 min•Backend / ML platform engineers, anyone considering Rust

NLP for Regulated Domains: Lessons from the Electrical Code

Building VoltVault meant ingesting the NFPA-70 National Electrical Code — 1000+ pages of tables, definitions, and references — into a semantic-search system that licensed electricians would actually trust. I'll walk through the chunking and retrieval choices, the failure modes specific to regulatory text, and what transfers to other compliance-heavy domains (healthcare, finance, legal).

30-45 min•ML engineers working on NLP or RAG in regulated industries

Production AI Tutoring at Scale

A look inside an LLM-backed tutoring system serving real students at a regulated education company, framed through the lenses of personalization, latency, and safety. The clinical-trial-adjacent constraints (no hallucinated medication doses, no leaked PII, defensible content) and how the architecture was shaped by them.

30 min•ML engineers, applied-research teams, education-tech / health-tech audiences

Organizing an event? I'd love to talk — drop me a line.

Let's Build Something Together

I'm always interested in discussing new projects, creative ideas, or opportunities to be part of your vision.

Interactive explainers for machine learning, statistics, and the systems behind them — built so each idea is something you can manipulate, not just read.
