Open source

Open source

I have created and contributed a significant amount of open source projects over the last few decades. These are the highlights:

2025 to present

Solana Program Examples

Maintainer

I maintain the largest examples of financial software on the world's most active blockchain. The repo started as small single-feature example programs and had fallen into disrepair. I forked it, fixed the broken code, ported it to Anchor 2 and Quasar, and added examples for exchanges, options trading, parimutuel betting, and other kinds of financial products.

2009 to present

python-docx

Creator

The Python library for creating, editing, and saving Microsoft Word documents. I created python-docx in 2009 after needing a native way to read Word documents in Python. Microsoft uses it to read Word files in its own AI tools.
