AI System Design - Learn how to design AI systems built on LLMs, RAG, and AI Agents step by step.

Learn it. Build it. Ship it for others.

Build a modern LLM from scratch. Every line commented. Explained like we are five.

tiktoken is a fast BPE tokeniser for use with OpenAI's models.

AI agent toolkit: unified LLM API, agent loop, TUI, coding agent CLI

An interactive app that walks through every stage of the LLM pipeline, from pattern matching to training a transformer from scratch, with working code you can run locally.

Neural Networks: Zero to Hero

Low-latency tick-to-trade engine: ITCH/OUCH order book over kernel bypass (ef_vi), with hardware-timestamped latency measurement.

Institutional-grade market data infrastructure: converts noisy, multi-venue exchange feeds into a validated, sub-microsecond canonical stream with cryptographic auditability and zero silent drops.

A curated list of awesome Claude Skills, resources, and tools for customizing Claude AI workflows

Production-grade engineering skills for AI coding agents.

An agentic skills framework & software development methodology that works.

Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.
