Walmart Global Tech July 2022–Present

Sr. Software Engineer

● Led a project to migrate over 50 kafka topics from the public cloud to Walmart’s private cloud. The topics are used by over 30 teams and required significant coordination to migrate while avoiding data loss.

● Overhauled test suites for several Java apps to add functional testing and increase code coverage to over 90%.

● Performance tested REST endpoints on eight applications using Walmart’s SaaS continuous testing platform. Determined the maximum throughput for a single production-like pod for each application, which was used to size the apps and prepare for Walmart’s stress testing for the holiday season. TED Conferences, LLC Nov 2021–July 2022

Backend Engineer

● Updated a critical application from Rails 5 to Rails 6. The update allowed the team to add a new framework that was incompatible with Rails 5 and prevented the application version from reaching the end of life.

● Automated the scheduling of podcast releases that previously required weekly developer intervention.

● Migrated our internal software packages from a private server to Github Packages, allowing the team to end support for the old server and improving security. Inventables, Inc. Jan 2021–Nov 2021

Software Engineer II

● Overhauled the site’s caching scheme from observer-based caching to Russian-doll nesting fragment caching.

● Re-wrote the site’s shipping code to integrate with our third-party-fulfillment API and support multiple shipping methods and fulfillment locations. The improved shipping code enabled the team to efficiently manipulate the shipping cost charged to the consumer and apply promotions such as free shipping.

● Integrated third-party protection plans for Inventables’ best-selling product. Inventables, Inc. Dec 2019–Jan 2021

Software Engineer I

● Worked collaboratively with Inventables’ designer to create a landing page for Inventables’ October 2020 product launch using CSS grid, CSS flexbox, and vanilla Javascript.

● Supported and developed new features for a 10-year-old Rails-based E-commerce website hosted on AWS. The site is a Rails monolith with a stack that uses Rails 4.2, jQuery, vanilla Javascript, and Bootstrap.

● Set up email notifications for an API error that previously failed silently. This helped us catch an unannounced API update that was causing our code to fail, which allowed us to find and fix the problem within hours.

Groupon July 2019–Dec 2019

Ruby on Rails Engineer

● On a small team of just two developers, took over support of a legacy Rails application that interacted with Groupon’s large databases in an ecosystem with hundreds of microservices. This application managed customer-facing data, processed customer information, and managed customer funds.

● Created a tool to automate the removal of customer personally identifiable information from Groupon and its partners’ databases to comply with the GDPR. This tool eliminated the need for a script that was previously run daily and was prone to human error.
