Modern AI Systems
Actually Work
Deep dives into voice AI, fine-tuning models, realtime infrastructure, RAG systems, LLM engineering, and production AI architectures.
Written by an engineer who ships, for engineers who ship.

What ships in every issue
No fluff. No hype.
Just the systems thinking.
That separates engineers who ship from engineers who scroll.
Voice & Realtime AI
PSTN → SIP → RTP → LLM pipelines. How audio travels through the stack and where latency hides.
Voice AI · Realtime Infra
RAG & LLM Systems
Retrieval pipelines, context windows, chunking strategies, and the evals that tell you if any of it works.
RAG · LLM Engineering
Production Architecture
Infrastructure decisions, tradeoffs, and system diagrams from AI products actually running in prod.
Production AI · Fine-tuning
