  • CrackaJack Digital Solutions Website (2022)

    I developed this company's website using React, TypeScript, SCSS, and AWS serverless and designed each page and section based on loosely defined requirements.

    The goal of the project was to modernize their old website to help stand out from competitors and impress potential business partners. I also built their old website in 2017—the link to a backup of their old website:

    The new website has built-in admin controls created with AWS Lambda and DynamoDB, so employees can log in and update content such as adding team members, testimonials, or job listings.

    I received high praise for this project from the company and its partners. One of the testimonials: "Greg, do you have mini-clones of yourself? This work is amazing, and we would love to leverage your talent at higher scale for more projects." – VP of Sales, CrackaJack Digital Solutions

  • Left-Hand Navigation for Wayfair's Multi-Class Pages (2022)

    I implemented the left-hand navigation links for specific page types on Wayfair's website. The implemented category links can be seen on any of the Wayfair brand websites, including AllModern, Joss&Main, and Perigold. I led the project from development to completion over three months and implemented the requirements defined by the product and design teams. The analytics team calculated the impact of an increase of $10.5 million in gross revenue in sales (GRS) annually based on their A/B testing and analysis.

    The tech stack involved with this project included PHP and React. Many bugs and issues came up and were resolved during the rollout of this feature. I worked closely with QA, product, and stakeholders to ensure the project met the definition of done and was completed according to Wayfair's standards.

  • (2021)

    A web-based API documentation platform made using React and AWS serverless. This service allows users to host RESTful API documentation and share it with other users. With the built-in API editor, they can also upload existing Swagger files or create new API documentation from scratch.

  • Nike—Midgard (2019)

    Leveraged the Java FreeMarker template engine (FTL), JavaScript, and CSS to develop the front end for this internal web application and replace a sunsetted tool (Netflix's Asgard). The nd tool is used across Nike's engineering organization by cloud-based teams to manage the scaling of their AWS EC2 ASGs and instances. Due to many teams and services in a few shared AWS accounts, developers constantly faced throttled requests in the AWS console and CLI. This tool leverages caching to prevent throttling and allows developers to view and scale AWS resources as often as desired. The tool only replaces a subset of the functionality that Asgard provided. The result is that engineering teams could operate as usual with little to no impact from the loss of the heavily used Asgard tool.
