Stephen: ColBERT-Style Neural Retrieval for Elixir
ColBERT-style late interaction retrieval for Elixir. Per-token embeddings and MaxSim scoring for more precise search than single-vector approaches.
Elixir/BEAM Doesn't Solve Everything for AI Agents. Addressing the Criticisms.
Addressing the three most valid criticisms of using Elixir and the BEAM for AI agents.
Alike: Semantic Similarity Testing with the Wave Operator
Test LLM outputs by meaning, not by characters. A wave operator for semantic similarity assertions in Elixir, powered by local embeddings.
Your Agent Framework Is Just a Bad Clone of Elixir: Concurrency Lessons from Telecom to AI
Python and JavaScript/TypeScript AI frameworks are reinventing what telecom solved in 1986. What 40 years of production-grade concurrency teaches us about building AI agents.
The Boring URL Shortener: System Design Interviews on the BEAM
The classic system design interview opener: design a URL shortener. Each follow-up is supposed to be harder than the last. On the BEAM, they're boring.
Full Stack AI with Elixir: San Francisco Global Elixir Meetup Talk
My talk at the San Francisco Global Elixir Meetup on building full-stack AI solutions in Elixir: multiple chains, in-memory RAG, MCP clients, and neural networks in your supervision tree.
Elixir Mentor Podcast: Forecasting, AI Agents, and the BEAM
I joined the Elixir Mentor podcast to talk about Soothsayer, why the BEAM is the best runtime for AI workflows, and agentic commerce.
