ADP

Overview

I was a Software Engineer at ADP, working on ADP Run, an enterprise payroll platform serving 800,000+ clients.My main project was rebuilding the B2B client onboarding system. I built React components, optimized workflows, and reduced client setup time by 40% while maintaining WCAG compliance. Note: Specific screens cannot be shown due to confidentiality.

The public product: ADP Run

My Role

What I built

  • React components for client onboarding workflows
  • Multi-tenant B2B interfaces integrated with C# APIs
  • WCAG-compliant forms and data tables
  • Performance-optimized components for 800K+ users

Technologies

  • React, TypeScript, JavaScript
  • HTML/CSS, TailwindCSS, Responsive Design
  • WCAG-compliant forms and data tables
  • C# RESTful APIs
  • Jest, Cypress, Mocha
  • Git, Jira, Jenkins CI/CD

Key Achievement Reduced client onboarding time through component optimization and streamlined user flows.

Outcome

My work on ADP Run directly served 800,000+ clients across the United States, handling billions of dollars in payroll processing annually. I built React components and optimized workflows that met WCAG 2.1 AA compliance standards, maintained sub-second response times, and supported thousands of concurrent businesses with different configurations and needs.


The client onboarding optimization was my most significant contribution, reducing confusion and excessive third-party communication between sales teams, CPAs, and finance professionals by 40%. By streamlining the user interface and creating clearer workflows, I helped clients complete setup with less back-and-forth, reducing support burden while maintaining enterprise-grade reliability and accessibility standards.


What I Learned

Building for hundreds of thousands of users taught me performance optimization, accessibility standards, and how to work within large engineering teams. I learned to balance technical excellence with business requirements while maintaining code quality at scale.
