The language app I wanted for myself. American English and Brazilian Portuguese, with audio, visual vocabulary, and practice in both directions.
Projects
Courses, learning apps, and tools for working with AI agents. Each project has its own purpose; you can open it or look through the code.
AI Academy
A course on how language models and the systems around them work. From the basic mechanism to RAG, infrastructure, and implementation.
Agent Run Checkpoints
A public companion to my notes on bounded AI agents: task contracts and checkpoints for keeping agent work traceable.
Modern Python
A practical Python course with exercises, checkpoints, and a capstone project. Optional AI labs sit alongside the programming work.
