Experience
Optimized Tree Pattern Matching Engine for Python's 2to3
I wrote a more efficient pattern-matching engine for Python's 2to3 tool that can combine multiple n-ary tree patterns in a single automaton using a novel algorithm. It's now a part of the standard Python library and still in use by 2to3.
NLTK TextTiling Implementation
I contributed to the implementation of the TextTiling segmentation algorithm for the NLTK project.
Xen Paravirtualized Audio Driver
https://code.google.com/archive/p/xen-audio/This is a paravirtualized audio driver that I wrote for Xen as part of a Google Summer of Code project. The driver was functional but was never integrated into Xen as the project moved away from Linux desktop virtualization.
k6 WebSocket Support
A small project that I finished recently that adds WebSocket support to the k6 load-testing framework.
Transfer Learning in Multi-agent Reinforcement Learning Domains
A paper I presented at the European Workshop on reinforcement learning and subsequently published in the conference proceedings as part of the Lecture Notes in Computer Science series by Springer.
Elm-based Unit Comparison Utility for Age of Empires II Fans
https://github.com/gbts/aoe2calcA hobbyist project that I started a while ago as a way of learning Elm that ended up attracting a small userbase.
