Introduction

I'm a CNC machinist with over a decade of experience in the trade. I specialize in lathes and turning centers but I also have experience with mills, machining centers and many other manual and automated machine tools.

I love working in manufacturing. I am always seeking out new opportunities to learn and expand my skill set. Recently I have started building upon my lifelong interest in computers by learning to code with freeCodeCamp.org. All of my home computers run GNU/Linux (Debian). I'm a supporter of Free and Open Source Software; I am a member of The Free Software Foundation and The Open Source Initiative.

I wrote a program in Python that creates NC programs for several gages and fixtures commonly needed in SES seal production. Another program I wrote in Bash script checks NC programs for common syntax errors like open comments or overly-precise decimals. These errors are then compiled into a report. Both of these projects can be found on my GitHub page.

Creating these programs got me excited about the prospects for solving problems, organizing, and automating processes in the factory with code. That is why in November 2019 I enrolled at SNHU to start working towards a BS in Computer Science.
