About Aayush

I’m a Workday Solution Architect with 8+ years of experience delivering high-impact integrations across HCM, Payroll, and Finance for global organizations.

I don’t just build integrations — I design systems that don’t break.

I’ve worked across enterprise environments where Workday is business-critical, handling complex integration landscapes, multi-country payroll, and financial systems that require precision, scalability, and zero room for error.

What I do best:
  • Build and optimize Workday Studio, Core Connectors, EIB, RaaS, and API integrations
  • Deliver payroll (PECI) and finance integrations including banking formats (ISO Pain001, Pain008, EFT, Wire)
  • Fix broken integrations and stabilize production environments fast
  • Design scalable architectures that reduce long-term maintenance and failures
What sets me apart:
  • Delivered large-scale solutions with zero critical production issues
  • Built frameworks and reusable models reducing delivery timelines by 40%
  • Trusted by stakeholders to handle complex, high-pressure delivery environments
  • Strong ownership — I step in, take control, and deliver without hand-holding
Leadership & working style:
  • Act as the backbone of delivery teams, ensuring consistency, accountability, and momentum
  • Equally strong in leading teams and executing hands-on work
  • Work seamlessly with any stakeholder — business, technical, or leadership
  • Create structured, accountable environments where teams stay focused and deliver reliably
I’m typically brought in when things are complex, critical, or already going wrong.

If you need someone who can understand fast, lead confidently, and deliver clean, production-ready solutions and if you are someone who don't like escalations — let’s talk
