Work Experience
- I am working as a Product Engineer in the Special Products Group of Fisher Controls in Marshalltown, Iowa. I am responsible for answering and providing engineering input to inquiries from sales and manufacturing around the world for a number of Fisher sliding stem product lines. Additionally, I work on engineering orders that are outside the scope of Fisher’s normal catalog, which often contain unique material, temperature, and/or pressure requirements.

Projects
MSFS Mod Manager
MSFS Mod Manager is an external mod manager for the new Microsoft Flight Simulator. It lets users quickly install and manager their third-party addons for the simulator. It has over 30 stars on GitHub and is built with Python 3 and PySide (Qt).

Linkspring
I developed a severless web app for users to create a page to consolidate all of the links they want to share with other people (Facebook, Twitter, Instagram, GitHub, etc) in one place. I have solely done all of the work on it including design, back-end work, front-end work, and development automation. It is primarily built with the Python Flask framework and runs on AWS Lambda with DynamoDB as a database. The vast majority of the codebase is covered by unit and integration tests which are automatically run on every pull request. Every component, including a duplicate development copy, is hosted within AWS. Billing is handled by Stripe.

Physics Light Guide
I modelled an apparatus to channel light into a series of detectors for an experiment a professor was working on in the Physics department. At the base is a 10cm x 10cm calorimeter of 47 x 47 fiber optic fibers. The light coming out of these fibers needed to be funneled together into a 5 x 5 array of detectors. Multiple different variations of parts were designed with differing wall thicknesses and heights to accomplish this. One concept was intended to be injection molded as a single part, with an interior mirror finish. Another concept was to laser cut pieces of mirrored stainless steel and glue them together into separate “towers”. I made all of the parts in Solidworks with a lot of lofts and different configurations (as 47 doesn’t split into 5 nicely, the groupings of fiber optic fibers had to be differing sizes).

My Blog
On my blog, I make posts about various projects or technical challenges I have been working on. All content is written in Markdown. There is no ad revenue from it and is just something that I enjoy writing.

pyQstat
pyQstat is a small Python-based web app to display Sun Grid Engine (and forks) statistics. This was built for the High-Performance Computing cluster mentioned before.

High-Performance Computing Cluster
I assisted in designing and constructing a Beowulf-style compute cluster for PrISUm out of recycled hardware. The cluster consisted of seven desktops with quad-core Intel Core i7 processors with 8GB of RAM, each running a build of CentOS. This gave the cluster a combined compute capacity of 28 CPU cores and 56GB of shared memory. All of the nodes were connected on a local gigabit ethernet network. The head node of the cluster ran Sun Grid Engine for job scheduling and had 1TB of network storage for applications and user workspace. The cluster was primarily used by the team for computational fluid dynamics simulations with STAR-CCM+ and MATLAB optimization problems. When the cluster was not in use, it contributed to community grid computing projects.

My Website
Using what I learned while building prisum.org, I rebuilt this website around the Hugo static site generator. The content and theme are tightly coupled around structured data files (example). The theme is built with MaterializeCSS for the main CSS framework, lazySizes for lazy image loading, and MixItUp for categorizing projects. Multiple npm scripts along with CloudFlare pages are used to automatically generate all CSS and JS assets, build the site, and publish it on every commit automatically.

PrISUm Website
I rebuilt the prisum.org website completely from scratch with new content management software. Previously, the site was entirely hand-coded, which made updates extremely difficult and time-consuming. Rebuilding the site with new browser-based content management software and templating massively increased maintainability, along with allowing non-developers to easily and quickly make content updates. In the process of rebuilding the site, I implemented lazy image, font, and CSS loading, automatic image resizing and compression, critical CSS generation, and no-reload page transitions which reduced monthly bandwidth usage and page load times by 95%, improving SEO.
