Hi, I'm Tony Aldon

I'm a Python developer based in Spain, with a background in mathematics and teaching. I build scripts and CLIs using the OpenAI API, develop Emacs tools, and contribute to open source.

Most of my work so far has been through independent projects, open-source contributions, and technical education.

I'm looking to join an engineering team building and maintaining Python backend services, AI integrations, or developer tools.

What I'm building¶

I'm extending Eden, my OpenAI API client in Emacs Lisp, with coding agent features. The client itself is stable.

My recent Python work includes scripts using the OpenAI API and a CLI that enriches French-English phrasebooks with AI-generated translations, audio, and images.

Plus, I've started building FastAPI backends with PostgreSQL and deploying them on AWS using Docker to develop my backend skills.

I write about the implementation details: testing API integrations, handling errors, debugging unexpected behavior, and improving tools.

A few places to start:

Open source and teaching¶

Previously, I contributed Python tests and tooling to the Bitcoin Core Lightning project, including a JSON-RPC client and a plugin library.

I've also published around 170 coding tutorials covering Python, Emacs Lisp, and C, with a YouTube audience of more than 1,200 subscribers. I've presented projects at EmacsConf and PyConES, and published the course Build a ChatGPT Client in Emacs Lisp.

You can explore my open-source work, videos, and conference talks.

Working with AI¶

I write Working with AI, a newsletter about learning, thinking, and working with AI tools. It helps me reflect on using these tools.
