• Serving as a senior full stack developer on Instacart’s high profile Caper Cart product. On the front-end, I work on the Cart Manager web app at cloud.apps.caper.ai which provides management capabilities for over a thousand smart carts in both the United States and Europe. On the back-end, I work on our Java/Kotlin Springboot Microservice architecture to support the backend functionality of the carts. • I led the architecture and implementation of several high profile projects: (1) shrink proxy (estimate average retailer shrink per shopping session), (2) location based audits (alert when customer adds a product in an unexpected location), (3) videoless audit resolution for a retailer with GDPR restrictions that prohibit video recordings and (4) coordinated audit review system that used temporal engine to orchestrate cart audit reviews by remote inspectors that reduced our false positives. I used react, typescript, node.js, python, Java springboot, Kotlin, grpc-web, and GCP for these projects. • Increased our front-end code coverage from 25% to 70% in 8 weeks by replacing React Testing Library with Cypress Component Testing and teaching integration testing & TDD best practices to the web team. • Introduced Postgres integration test harness to our Java Spring backend which has been adopted by all backend team members.

• Built the GoPuff Forecasting and Planning Platform from the ground up using GraphQL, Apollo Server, Apollo Client, React, Node.js, TypeScript, HTML5, CSS, Chakra UI, and React Viz on top of Azure Cloud• Served as the most senior individual contributor of the Forecasting Engineering team for my entire tenure. Our platform enabled a team of 4 analysts to accurately forecast order volume and delivery partner personnel requirements for over 600 micro fulfillment centers across the United States and Europe.• Architected the GraphQL design patterns, database schemas, and front-end architecture for the Forecasting and Planning Platform by mentoring junior developers and making over 2 dozen presentations internally to the team on topics ranging from back-end and front-end engineering, caching, databases, progressive delivery techniques and more.• Drove adoption of back-end and front-end test-driven development within the Forecasting Engineering team and throughout the GoPuff company by introducing a custom built GraphQL TDD harness based on patterns I learned by studying IntegreSQL and Apollo Server Integration testing as well as the latest testing hierarchy theories for front-end development to enable TDD with React Testing Library.• Increased our front-end code coverage from 0 to 70% in 5 months, and our back-end code coverage from 10% to 70% in 2 months. Also decreased regressions by over 25% in 6 months by introducing TDD.• Earned the company’s highest performance review rating of “Always exceeds expectations” and waspromoted from Software Engineer II to Senior Software Engineer in 11 months.

• Built the entire GameBling.com e-sports web and desktop application from the ground up using React.js, javascript, HTML5, and CSS on the front-end, node.js for the web tier and microservices,SourceMod for the game scripting on top of the Source Game Engine, MySQL 8 for the database tier, and AWS Cloud for the infrastructure (EC2, Lambda, RDS, SNS, CloudWatch, Route53).• Collaborated with designers, other developers, and our pro gamer clients to engineer a robust, scalable platform for entertainment gaming.• Responsible for engineering standards and software development workflow across the project.• Released various open-source software modules to solve unsolved problems I came across such as database driver stability and theoretical mathematics related to efficient subset detection. Seehttps://github.com/thorpep138 for details.

• Served as Chief Technology Officer and lead hacker of the e-sports company from 2012 to 2014.• Built the web architecture and real-time game server from the ground up to a high-scale distributed system, leading the engineering team in the process.• Provided technical direction that helped secure the first funding round.• For press, see: https://www.dailyprincetonian.com/article/2014/02/students-launch-beta-version-of-video-game-start-up-digitalcade

• Developed a real-time anomaly detection system for streaming log data of internal central authentication system built on top of HTTP.• Implemented big data pre-processing by coding Hadoop Map-Reduce jobs.• Leveraged Mahout classes for statistical analysis to transform the data into a suitable form for Interquartile Range (IQR) analysis.• Built the real-time anomaly detection component using the complex event processing engine Esper. • Researched data mining techniques applicable to our data, and produced prototypes using k-means and canopy clustering.

• Developed UI/UX and server-side solutions and fixes for corporate and consumer facing sites using Zend Framework, PHP, T-SQL, Prototype JS, HTML, CSS, and subversion for source control. • Implemented back-end functionality and inline pagination for an internal Web 2.0 activity feed, collaborating with the other three NY Interns for this Intern Project.• Extended Facebook Integration on public consumer rewards site.• Coded dynamic graphs of incoming user and transaction data using twitter bootstrap, Rickshaw D3 JS Toolkit, JQuery, T-SQL, and PHP.• Hacked the Xbox Kinect in group of three to create gesture-based TV shopping demo, achieving runner-up for most innovative product in company hackathon.

• Assisted IT security operations personnel in a wide range of IT security activities, including management of IT security systems and applications, network and system security assessments, and programmatic support.• Required knowledge of programming fundamentals, networking principals and operating system functionality, technical risk, and vulnerability management practices at the network, system, and application level.• Used enterprise level security systems such as Splunk, Nessus, and AppDetective, as well as standard windows programs for the tcp/ip suite.

• Completed various programming, database, scripting, and web design assignments in a timely manner for Dow Jones data department.• Wrote scripts that manipulated databases in ruby and bash, as well as program the MySQL databases themselves using Server Query Language on a machine running Linux CentOS 5.0. These tasks often involved IP addressing and XML. • Scripted dynamic web pages to display data graphically using ruby on rails, xhtml, css, javascript and the ViM text editor. This task also required installation of apache, webrick, and subversion.

• Involved heavily in all designing, coding, testing, and management for all of the php scripting, database administration, and front end modification for the up and coming social networking website www.classmatcher.com.• Requires the use of apache, xhtml, css, php, ajax, javascript, jquery, MySQL, and the Facebook Social Graph API for Faceboook Integration. • Has served hundreds of users.
