WatchExchanger.com Webapp

(see video for code samples, repo is private)

WatchExchanger.com is the first Micro SaaS businesses I've released. This website is designed as a companion app for the Reddit.com r/WatchExchange subreddit community (over 300k members). As of July 2023, the app sends thousands of notifications per month to its growing user base.

I've built it using the Amazon AWS Amplify tech stack, featuring the React.js javaScript framework for the frontend and an AWS Lambda serverless backend. For data, it utilizes a DynamoDB database interfaced with GraphQL. Account user pools are managed with AWS Cognito, and all messaging is done through AWS SNS/SES. The app also integrates Stripe as the payment processor.

In this demo video, I go over various aspects of the app, including some live demonstrations of user-flows and some code segments. The video runs for over an hour, but don't worry: I've included video chapters in the progress bar so you can easily jump to the sections you're most interested in.

Microsoft HoloLens Eye-Tracking Research

During my senior year at Texas A&M University, my partner and I had the opportunity to work on an augmented reality project for our undergraduate capstone design assignment. We utilized the Microsoft HoloLens 2 system to bring our vision to life. Our research, conducted under the sponsorship of the TAMU Electrical Engineering Department, involved mainly writing code in C# for the Unity platform.

Our project was selected as one of the featured projects at the Texas A&M 2021 Engineering Project Showcase, out of a pool of over 200 teams. Check out the final product demonstration in the video below to see our hard work come to fruition!

USAA Disclosures Components Demo App

(see video for code samples, repo is private)

As a software engineer intern at USAA, my primary focus was on frontend development, utilizing the React.js JavaScript framework with Redux state management, and testing with the Jest framework. To showcase my accomplishments and share my experience, I delivered a capstone presentation to nearly 50 of my peers.

I later returned to this same team at USAA where I did much more work (both UI and API) around the components featured in my capstone. I actually ended up migrating the services relating to this UI to the Java API framework, Spring Boot (this service is called over 300k times per day, as of July 2023!). However, the demo app shown in this capstone presentation was still used for many years.

You can watch the complete presentation in the video below for an in-depth overview of my work as an intern.

Point Tracker Webapp for A&M Engineering Honors

(https://github.com/zsteen13/EH_ExComm_Participation_Tracker)

In my senior year of college, I enrolled in a software engineering course where I took on the dual role of product owner and core developer in an Agile Scrum team. Our project was to create a point tracker application for TAMU Engineering Honors.

As the product owner, I acted as the liaison between our development team and the client, translating user requirements and concerns into meaningful stories for our team to tackle. Meanwhile, as a core developer, I gained invaluable full-stack development experience, building the application from the ground up using the Ruby on Rails full-stack framework deployed to Heroku, and a PostgreSQL database. The app also had much HTML, CSS, and JavaScript work involved, as well as testing with Capybara.

Check out the final product demonstration in the video below to see the results of our collaborative efforts.

San Antonio, TX Architectural Drafting

During my tenure at Atriecon SDG, I was responsible for converting legacy C code, initially written for 16-bit machines, into modern C++ code suitable for contemporary computers. In addition to this, I worked extensively on drafting detailed designs in AutoCAD.

These designs are now being employed by contractors in the construction of multiple storage facilities across San Antonio, Texas. To get a glimpse of some of the drawings I completed while working at Atriecon SDG, take a look at the images provided below.

ZacharySteen.com Portfolio Website

(https://github.com/zsteen13/zsteen13.github.io)

That's right! This website is a key component of my portfolio. Built using HTML5, CSS3, and JavaScript, it's based on a designer's Creative Commons free stylesheet from HTML5UP. Additionally, I've integrated widgets created by other developers for the carousel images and the fillable contact form you'll find below.
