about me
Hi, I'm Garrett. Welcome to my corner of the internet.
I'm a computer scientist and software engineer specializing in software/systems architectures and programming languages. Some of my more recent projects include the Swarm programming language, the Extollo framework, and the CoreID SSO server.
I sometimes write blog posts and publish code from my projects.
what I'm working on
HackKU 2022
HackKU is the University of Kansas' annual hackathon.
My group participated for our fourth year in a row where we built CrystalMath, a graphical, interactive worktable for math applications.
Our project was the runner up in the education track and also received the award for best domain name for crystalmath.tech.
Honors Seminar Assistant
During the Fall 2021 semester at KU, I assisted with an honors seminar section
about algorithms and their applications to fields outside computer science.
Among other activities, I prepared and delivered a lecture on the halting problem.
Swarm
Swarm is a programming language that abstracts parallel & distributed computing initially created by me and my senior project group at KU. Since then, myself and Ethan Grantz have continued working on Swarm and have released it as an open-source project.
HackKU 2021
HackKU is the University of Kansas' annual hackathon.
My group participated for the third year where we built Loc-Chain, a blockchain-based, anonymous contact tracing solution.
Extollo
Extollo is a fully-featured, opinionated application framework written
in TypeScript.
The framework is still a work-in-progress, but so far includes a dependency injector, boot framework, ORM, job queue, routing stack, and a robust set of TypeScript utilities.
This website is powered by Extollo.
Starship CoreID
I an an avid self-hoster. As such, I have a lot of disparate apps that all have different login schemes, which can be a bit annoying to manage for myself and friends.
So, I decided to build a unified login system similar to things like CAS. CoreID supports OAuth2, OpenID Connect, LDAP, and SAML2 with universal 2FA and granular access controls. This project has taught me a lot about the different SSO stacks.
TeraCrunch, LLC
TeraCrunch is a Kansas City-based data analytics and machine learning firm.
I worked with them as a freelance systems engineer to handle infrastructure projects like backups and scheduled jobs, and smaller client projects such as a statistics aggregator, and Node.js application enhancements/maintenance.
HackKU 2020
HackKU is the University of Kansas' annual hackathon.
My group participated for the second year where we built Noded, a rich-data note-taking app designed to help people build personal information trees.
I liked this concept so much that I've continued improving it since then, and I use it for my personal notes to this day.
AllofE Solutions
AllofE is a software company in Lawrence, Kansas, primarily focused on the eMedley web suite for higher-education.
I work as a software engineer doing full stack development in PHP/SQL/Angular. Of note, I designed and built a new automated proctoring flow used by 10+ schools built on TensorFlow and AWS Lambda. I also helped integrate and transition 50+ models and infrastructure components from a legacy framework to Laravel.
HackKU 2019
HackKU is the University of Kansas' annual hackathon.
I participated with a couple friends and we built WaitNoMore, a multi-tenant parking management app built on Python, Firebase, and Flutter.
For this project, we were awarded the Best Implementation of Google Cloud.
Flitter
Flitter was my first take on a Node.js app framework, which has been deprecated in favor of Extollo.
I started it as a learning project and eventually built it out to include a unit-based startup framework, a dependency injector, an ORM, a job-queue wrapper, an auth framework, and more.
Center for Research Methods & Data Analysis
The CRMDA was a University of Kansas lab that assisted researchers with data analysis projects and computing.
I worked as a lab system technician there my freshman year of college maintaining the CentOS lab workstations, transitioning 20+ cluster scripts to the SLURM scheduler, and creating a proof-of-concept Kubernetes cluster on which I help a colloquium.
University of Kansas
I studied computer science at the University of Kansas and received my bachelor's of science with university honors and highest departmental distinction. I also completed a minor in business.
KRS Corporation
The KRS Corporation is an enterprise manufacturer based in my hometown.
I worked there over the summer assembling various components. Of note, I designed an Arduino break-out circuit to automate the flashing of these components. This system reduced the time required to program the controller boards by half.
Unified School District #416
USD 416 is the school district in my hometown.
As a summer job, I worked as an IT technician where I helped replace 50+ access points as part of a wireless deployment, imaged 100+ computers using Novell and Active Directory, and assisted with user support.
TEDxYouth@Louisburg
For two years, I served as the technical-director of TEDxYouth@Louisburg and helped organize and live-broadcast the first TEDxYouth event at a high-school in Kansas.
Particularly, I helped plan schedules for breakout rooms, built the sign-in and ticketing system, and directed the live-production of the event itself for 150+ guests.

latest updates
Down the Rabbit Hole of Linux Terminal Emulators
I've had a pretty stable shell setup consisting of Guake + Fish shell for ~5 years now.
Recently, I decided I wanted the ability to copy-paste output w/ screen and
the ramifications of this forced me to re-examine my entire setup.
Read about my foibles here.
Adventures in AI-assisted proof generation
Begrudgingly, I recently spent a bit of time playing around with ChatGPT and its prowess with the Coq proof-assistant language.
I chronicle my adventures, and some of my broader thoughts, in this blog post.
Retro/70s Redesign
On a whim, I decided to redesign this site to have a bit more character. Initially inspired by this cool album art, I tried to incorporate retro/70s design elements.
A fun element of this design is how parametric it is. The color palette can be completely swapped out for a complementary one. I built several different palettes and randomly select one for each visitor.
I'll do a more in-depth write-up of the process soon. For now, though, you can play with the themes on the technical info page.
Generalized Commutative Data Types
Recently, I've been working on a distributed, parallel language called Swarm. One challenge with such a language is ensuring consistent data operations when they are performed in parallel.
A GCDT is one approach to simplify this process. Such types define commutative and pseudo-commutative operations which allow order-agnostic consistency when accumulating parallel computations.
I describe such a system and explore its limitations in this blog post.
Importing an OpenVPN Profile on Fedora 36
I recently upgraded to Fedora 36 and discovered
that my VPN settings were completely broken and
I couldn't re-import it from the .ovpn file.
What ensued was an annoyingly difficult series of workarounds required to avoid bugs in OpenVPN, NetworkManager, and NetworkManager-gui.
I've detailed how to do it here.
Rancher K3s: Kubernetes on Proxmox Containers
I've been re-learning Docker and containerization and I decided to take the plunge and start converting my self-hosted environment over to Kubernetes.
This post details how I set up a Kubernetes cluster on LXD containers on Proxmox using Rancher K3s and NGINX ingress controller.
