About

Chris Ding is a highly skilled Backend Software Engineer with over 7 years of relevant experience in building tools and processes that leverage the cloud and distributed systems to manage and analyze large amounts of data. He is currently working at UiPath as a Backend Engineer - E2E Testing CI/CD (Developer Productivity), where he is responsible for project ownership and lead maintenance of multiple CI/CD pipelines for code gating, coverage analysis, and scheduled health checks on deployed environments for a team of 13 engineers. Chris is an expert in implementing Cypress infrastructure for reliable and performant testing of team's codebase, producing a set of Cypress scripts that rapidly seeds new tenants with data through the application's UI to allow QA to quickly, repeatedly test specific scenarios, resulting in 400 hours of saved QA time. He has also architected 3 build pipelines that replicate a completely new build of the application before testing, provision cloud databases, coordinate multiple services against provisioned resources, run tests in parallel, and publish analysis. In addition, Chris designed a custom virtual machine image preconfigured with software and specs optimized for testing, reducing pipeline run time from 35 minutes to 15 minutes. He optimized agent pool scale settings to decrease queue time from 15 minutes to less than one minute, resulting in 30% faster time to pass tests on a pull request. Prior to UiPath, Chris worked at Prometheus Research, LLC as a Backend Software Engineer, where he developed performant frontend data analysis and management tools using React, Redux, and D3JS, and used Python and Postgres to write APIs and ETL processes that aggregate and measure client data. He also handled the team's software packaging, build, and deployment to UAT and production using Ansible and Vagrant. Chris worked closely with data analysts to create data models in Postgres to describe client healthcare information and maintained 90% test coverage using PBBT, Doctest, and Unitest for all code on the team. Chris has a degree in Economics with a focus on Statistics from the University of Chicago, and he completed a program in Hack Reactor. He has a strong technical skillset, including Backend, test, Software Engineer, qa, infra, Postgres, ETL, Python, ui, Ansible, Research Scientist, Redux, Frontend, and SQL. Chris is passionate about working on problems of scaling, large data infrastructure, enabling engineers, and processes for ETL and reporting.
