I've been speaking at conferences and meetups since 2008, covering Elixir, Ruby, AI, software engineering practices, and open source. Topics range from building full-stack AI systems on the BEAM to engineering metrics and team culture. Below is a collection of talks, conference presentations, and podcast appearances.
Talks
Arcana: What If You Could Build Production-Ready RAG Entirely in Elixir?
ElixirConf EU 2026 · Málaga, Spain
Full Stack AI with Elixir
GEM San Francisco Meetup · San Francisco, CA
Multiple chains, in-memory RAG without a vector database, MCP clients for team autonomy, and neural networks in your supervision tree.
Full-Stack AI with Elixir: Simplicity and Scale to Millions of Customers
ElixirConf US 2025 · Orlando, FL
Building a full-stack AI system in Elixir: LLM-based chat, GPU-powered image moderation with Bumblebee, multi-agent orchestration, and LiveView dashboards, all in one codebase.
Soothsayer: Using NeuralProphet, Nx and Livebook to Forecast Business Data in Elixir
ElixirConf US 2024 · Orlando, FL
Bringing NeuralProphet-style time-series forecasting to Elixir: explainable predictions built on Axon and Nx, with Livebook for interactive data exploration.
Async Jobs in Phoenix
EMPEX NYC 2018 · New York, NY
How Elixir handles async jobs differently than Rails: no need for Sidekiq or Resque when you have GenServers and message passing.
Podcasts
Elixir Mentor: George Guimarães on Forecasting
Soothsayer (time series forecasting on the BEAM), AI agents, and why Elixir is quietly becoming the best runtime for agentic workloads.
