Author | Speaker | Hacker | Time Lord


I am a hacker (by the true definition of the term) with a passion for open source software.

I'm experienced in C++ and Python, with working proficiency in C, Java, Bash, FORTRAN, CSS, HTML, and SQL (plus a little Assembly on the side). I'm an expert in memory management, debugging undefined behavior, and advanced object-oriented programming. I deeply enjoy working with algorithmic efficiency, data structures, design patterns, and algorithms. I'm a Linux power user, LAMP IT, computer repair technician, and open source advocate.

Additionally, I have expertise in coding style, commenting, documentation, testing, project management, and C++ build systems.

I'm a member of the Open Source Initiative, and the Python Software Foundation. I am the Volunteer Community Manager for Mailspring. I serve as one of the community moderators on DEV. I've also been a mentor with the Washington State Opportunity Scholarship,

Cover for "Dead Simple Python"

Dead Simple Python

Based on my popular DEV article series, Dead Simple Python is written for existing developers who want to learn and master idiomatic Python without wasting time rehashing the basics of computer programming. Edited by Python experts, and packed with vibrant, realistic examples, you won't just learn how to write Python code; you'll learn to think like a native Pythonista!

I'm thrilled to be working with No Starch Press, the publishers of Python Crash Course and Automate the Boring Stuff With Python.

Icon for "Timecard"

Timecard 2.0

Time tracking should be simple. Timecard allows you to start, pause, and log how much time you spend, all from within a simple, unified interface. [Win/Mac/Linux]

This is a resurrection of the first software application I ever built. I've reimagined it in Python and PySide2 (Qt 5).
