Hi there 👋. Leodanis here!

I help developers make sense of Python and modern developer tooling, one clear and example-driven tutorial at a time.

Senior Technical Writer & Python Educator with 10+ years of Python experience and 7+ years writing for developers at every level. As a core team member at Real Python since 2020, I've authored 140+ tutorials (960k+ words) and contributed to 82+ video courses. This content reaches thousands of developers every week.

What I write about:

• Core Python & software design (OOP, SOLID)
• AI-assisted development (Claude Code, OpenCode, Copilot CLI)
• AI integrations (Ollama, LlamaIndex, PydanticAI)
• CLI and GUI application development
• Asynchronous programming
• Modern Python tooling (uv, pyenv, pip)

Here are a few samples of my work as a technical writer:

• How to Get Started With the GitHub Copilot CLI
• Context Engineering for Python Codebases
• Python Built-in Functions: A Complete Guide
• Python Classes: The Power of Object-Oriented Programming

Beyond the writing itself, I design the exercises, code examples, and quizzes that help readers actually apply what they learn.

Lately, I've been going deeper into AI-assisted workflows using coding agents like Claude Code to automate day-to-day tasks. Skills, hooks, subagents, memory files, context engineering, and prompt engineering are now part of my everyday vocabulary.
