Hi, I'm Clay Weidinger.
Senior Software Engineer, Team Lead, and Engineering Hiring Manager
Copilot
Drowning in sticky notes? Letting things slip through the cracks? Could you use a copilot? Put all your todos, notes, shopping list, and projects into Copilot. Access it anywhere. Copilot is a mobile, offline app that syncs your todos to the cloud. Throw away your stickies, prioritize your todos and get stuff done.
Frontend: Angular, Typescript, Ionic, Electron
Backend: Firebase with AngularFire2, Node/Express, ElasticSearch
CARFAXForClaims.com
Carfax Vehicle History data tailored to insurance companies' claim departments. Our team launched this site and migrated thousands of enterprise users to it. Its functionality grew to suit a variety of different classes of customers. We eventually built an Enterprise Integration API specifically for this website's functionality. Almost all the functionality is behind a paywall.
Frontend: React, Redux, Typescript, ApolloLinkState
Backend: Grails API backed by MySQL and MongoDB
CarfaxBIG.com
Carfax provides vehicle history data to a wide range of customers including dealers and car purchasers and sellers. My team rewrote the entire Banking and Insurance Group (CarfaxBIG) website including the 10 apps that sit behind it. My team also maintained and extended our xml/json Enterprise Integration API and large batch systems. Almost all the functionality is behind a paywall.
Frontend: A HTML/CSS/jQuery app served by Tomcat
Backend: A Groovy on Grails application backed by MySQL
Pitch Bid Calculator
If you play the card game pitch, you can put in your hand and it will calculate the probability that you'll win and the points you'll likely get from bidding a certain amount in a certain suit.
Frontend: A jQuery/Bootstrap app scaffolded by Yeoman/Bower/Grunt served up by Nginx
Backend: AWS API Gateway backed by a Java AWS Lambda (Used to be a Grails app on Tomcat before I migrated it to the cloud)
Framemark
Back in 2014, my team at Carfax was picking a web application framework for our rewrite of our main website. I created this application in my free time to score and rank various web application frameworks.
Frontend: An AngularJS Single Page Application hosted by Github.
Backend: A Golang Transformer converts the source data from RedMonk and TechEmpower.tsv files to json that the frontend can use.
Logger
Time and Money are scarce resources. We spend them constantly throughout the day. Logger enables us to track and visualize where those resources are spent. Check out the features by using the demo account.
Frontend: An AngularJS app with a client side ORM for offline capability served by Nginx
Backend: A NodeJS Hapi server backed by MongoDB
iRemediate
As a Physics First teacher from 2011-2014, I recognized the need for targeted, automated practice and feedback for students experiencing difficulties solving freshman physics problems. I implemented an digital tutor that enables teachers to input problems as they would a worksheet. Students log in to see unexplored or unmastered skills and the tutor walks them through the practice offering feedback whenever they are stuck or wrong.
Frontend: A dojo/jQueryUI app served by Nginx
Backend: A custom PHP ORM
Pitch Multiplayer Online Game
I wrote this webapp so that I could play short handed (less than 4 people) pitch (a card game) with my brother in Kansas City and my other brother in Columbia. It uses websockets to communicate.
Frontend: A jQuery/Bootstrap app scaffolded by Yeoman/Bower/Grunt served up by Nginx
Backend: A Groovy on Grails app that leans on websockets pretty heavily for the real-time features served by Tomcat
Seats
For the teacher who frequently assigns new seating charts, this app makes the process a breeze. You can import an Infinie Campus Gradebook Export, arrange the virtual room exactly how you have yours arranged, and assign students either randomly or to put your struggling students with your best students. Manual changes are as easy as dragging and dropping.
Frontend: A dojo/jQueryUI app served by Nginx
Backend: A custom PHP ORM
Growing Together LLC
Our family ran a small farm: chickens, cattle, and a large garden. I've started a Drupal where we shared the farm's happenings with our customers and extended family.
GTD
An implementation of David Allen's Getting Things Done that is easily searchable and prioritizable. This was the first app that I created so I wrote most of it without any libraries. It even directly utilizes XHR for AJAX. How far I've come since April 2013!
Frontend: A jQuery app with a custom CRUD component served by Nginx
Backend: A MySQL interface written in PHP served by Nginx

About Me
Dad, Husband, Software Engineer, Teacher, Nurse
The short story? I developed accounting and payroll desktop applications for a local software firm for four years before I graduated high school as valedictorian. I earned a BS in Physics, minor in Comp Sci and Math with a 4.0 GPA in three years. I switched gears and earned my BS in Nursing through an accelerated program. I served patients and families as a Trauma/Surgical ICU RN for three years. There I met my wife! I earned my MS in Science Education while nursing. I taught Physics First to ninth graders in the public school system for three years. My wife and I had our first child! I developed web apps that solve my pain points in managing my students' learning, my farming business, and my personal information and todos. Copilot is the only personal project that I continue to develop and support. Since mid 2014, I have been developing and maintaining enterprise software products for Carfax as a software engineer, team lead, and now as the product engineering hiring manager.
