about me

Hi! My name is Garrett. Welcome to my little corner of the internet. I'm a self-taught developer and tech-nerd. I create software that I hope makes people's lives better. I created the Flitter framework, Noded, and a couple other fun projects. I love to communicate my work, and help others pursue their projects, which is why I've got a long history of sharing about my passion. I write blog posts, create video tutorials, hold talks, and publish code from my projects in the hope that others will find it useful.

A bit more background: I grew up in the rural mid-west, so I taught myself everything I know. I'm a big fan of learning to code this way. I'm currently studying computer science at the University of Kansas.

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 engineering intern 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.

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.

University of Kansas

I'm studying computer science as an undergrad at the University of Kansas, with a minor in business.

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.

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.

Rethinking Dependency Injection in TypeScript

For the past few years, I've been experimenting with various paradigms for DI in JavaScript and TypeScript.

In the latest in my series of mad ramblings on dependency injection, I've written up my thoughts on the various paradigms I've tried.

New Features in Noded

Noded is a project I started at HackKU last year. It's a rich-data notes app designed to help people create information trees. I've been slowly improving it since.

  • File Box
    • In addition to the basic file uploader, you can now add "File Boxes" to your notes, which support nested structures and managing individual files.
    • Files in File Boxes appear in the universal search, and will open to their nested location directly.
  • Universal Search
    • Nodes that support full-screen mode now open directly from the search interface. This means that the open page is unchanged.
  • WYSIWYG
    • In-line links and images now render properly in view-only mode.
  • Databases
    • Added the "Hyperlink" column type for external links.
    • Added the "Link to Page" column type for referencing other notes.
  • Users can now drag-and-drop to re-order subtrees in the sidebar.

You can try Noded out here.

An Open Letter to Senator-elect Roger Marshall

Roger Marshall, Kansas Senator-elect, has expressed his intention to vote not to certify the result of the 2020 presidential election.

I feel very strongly that this is a dangerous and irresponsible move that goes against the core tenets of American democracy.

Read the letter here.

This letter is released in the public domain. Please, adapt it, share it with others, and most importantly, send it to your representatives. Call them, e-mail them, snail mail them to tell them to support free and fair elections.

Full-text search PDFs from Linux CLI

For an open-note exam, I wanted a quick way to full-text search PDFs from the command-line.

I wrote a 2-line script to help with that, using just find, grep, and pdftotext (common to most distros).

Get it here.

MiniQ: A bare-bones, CRON-driven job queue.

I wanted a simple way to queue jobs to be run in the background without having to run a separate daemon.

MiniQ is what I came up with. With just 3 files, MiniQ provides the ability to log jobs and the CRON script will run periodically and execute the queued jobs in the background.

Converting an Ionic/Angular Site into a Progressive Web App

For the last year or so, I've been working on converting an Ionic app to a progressive web app with offline support called Noded. I decided to write up my findings on how to do this with Angular service-worker.
