Hi, there. My name is Garrett, and I'm a computer scientist, software engineer, and speaker.

about me

Hi! My name is Garrett. Welcome to my corner of the internet. I'm a computer scientist, software engineer, and speaker. I like to build software to improve the developer/user experience. I created the Extollo framework, Noded, CoreID authentication server, and a couple other projects. I love to communicate my work, and help others pursue their projects. I write blog posts, hold talks, and publish code from my projects in the hope that others will find it useful. I also do a bit of consulting.

A bit more background: I grew up in the rural mid-west, and I got started by teaching myself everything I know. I'm a big fan of learning to code this way. I completed a bachelor of science in computer science at the University of Kansas, and I'm currently a graduate student studying programming languages and formal methods at KU.

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.

January 2021 - Present

Extollo

Extollo is the next iteration of my Flitter project. My goal is to use what I've learned from creating Flitter to create an even better and safer web app framework in Node.js built with Typescript.

The project is very much in the early stages, but so far includes a dependency injector, basic startup framework, and a Typescript-based ORM.

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.

March 2020 - February 2021

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.

February 2020 - February 2020

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.

February 2019 - February 2019

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.

August 2018 - April 2021

Flitter

Flitter is my take on a Node.js app framework.

I started it as a learning project, and have expanded it to act as a base for all of my personal apps. It includes a unit-based startup framework, a dependency injector, an ORM, a job-queue wrapper, an auth framework, and more.

August 2018 - May 2019

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.

August 2018 - May 2022

University of Kansas

I studied computer science at the University of Kansas and received my bachelor's of science.

March 2018 - August 2018

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.

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.

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.

The Ultimate Guide to Cleaning a Dell XPS 15 Keyboard

Recently, I've been having a really annoying issue with my laptop keyboard where some keys require multiple presses or lots of force when pressed to register a key stroke.

Since I like to try to repair my own stuff, at least as a first-line, I decided to do a quick write-up on how to remove and replace the key caps without breaking them to clean out the key wells.

multicrypt: a library for multi-key encryption

Recently, I've been working on adding secure vaults for user secrets to my auth server project, CoreID.

To implement shared-vaults, I wrote an implementation of multi-key encryption using enveloped keys. It seemed fairly useful on its own, so I pulled it out into a standalone TypeScript package called Multicrypt.

Multicrypt provides a simple interface for multi-key two-way encryption for arbitrary keys and values, and makes it easy to add & remove keys from the shared values.

Photo Challenge 01: Self-Portrait

One non-technical interest of mine is photography. I'm starting a new 30-prompt photo challenge, which I'll be posting on my blog.

The first challenge is a self-portrait. Mine tries to capture my technical side, and allowed me to tinker with depth of field and reflections.

Follow along here.
