Passion

Every record is someone's paycheck.

Pay, benefits, retirement. I treat each integration that way, and I don't stop at a workaround.

Knowledge

Deep in the Workday toolset.

Studio, EIB, Cloud Connect, PECI, PICOF, BIRT, SOAP and REST. Former Workday Partner Product Lead for Studio and Cloud Connect for Benefits.

Experience

Since Workday Release 11 (2010).

16 years in Workday and 30+ in enterprise software. 20+ Workday customers, payroll for 56 countries, and teams of 100+ integrations delivered.

Services

What I do

Four ways to work together. Most clients start with one problem and stay for support.

Build

New integrations

Designed, built, tested and handed over with a design document.

Best for a new vendor, a new country, or a new process.

  • Workday Studio, including boomerangs
  • EIB and Document Transformation
  • Cloud Connect for Benefits, HCM, Payroll
  • Payroll Interface: PECI, PICOF, GPC
  • BIRT statements and documents
  • SSO / SAML
Fix

Failing integrations

Runs that fail, finish with warnings, or send data the vendor rejects.

Best for a run that fails, warns, or gets rejected.

  • Root cause from the live build, not guesswork
  • Vendor rejection and error files explained
  • Fix tested before it touches production
Assess

Impact analysis

Know what breaks before it breaks.

Best for a Workday release, a merger, or a tenant move.

  • Twice-yearly Workday release impact
  • Tenant move to public cloud
  • New companies, locations, mergers
  • Integration inventory and field-level catalog
Support

Ongoing support

A set block of hours each month for the integrations you already run.

Best for teams without an integration specialist on staff.

  • Post go-live and hypercare
  • Open Enrollment readiness
  • Vendor file changes and new fields
  • Documentation your team can keep

or pick what you're seeing

Connections

Connected to the systems your people depend on

From global payroll to the smallest benefits carrier. Wherever a wrong record means a wrong paycheck or a missed deduction.

Approach

What working with me looks like

No mystery. Here's how an engagement runs, and what you get at each step.

We talk it through

A 30-minute call about what's breaking or what you need. Then I get the access I need, and nothing more.

You getA plain read of what's likely wrong, and what it will take.

I trace the live build

I read what's actually running in your tenant: the integration, its reports and the business processes around it. Not old documents.

You getWritten findings, including when the cause is configuration and not the integration.

Fix and test

I fix it in a sandbox and test it with masked data against a written test plan, before anything reaches production.

You getThe test cases and their results.

Go live and hand over

We move it to production together, and I watch the first runs.

You getA design document and a decision log your team keeps.

My promises

  • I'll tell you what I find, even when it isn't the integration.

  • If I don't know yet, I'll say so. I won't guess.

  • You work with me, not a junior team.

  • Everything I build is yours, documented.

  • Your employee data stays masked.

About

Hi, I'm Bharat.

I've worked on Workday integrations since Workday Release 11 (2010), and in enterprise software since 1993.

I started at DayNine as one of the first integration consultants at a Workday partner, led teams on projects with 50 to 100+ integrations, then spent five years at Sanofi running HR integration. Since 2020 I've worked independently through IntSysGuru LLC, with Workday customers directly and through implementation and staffing partners.

You work with me directly. No hand-offs to a junior team.

Passion

Hiking

Nature, and the law of nature. Life's stubbornness to grow anywhere. Like a river: continuous and changing, the greatest constant.

Knowledge

Photography

Making memories, and the joy of reliving the moment. The details. Focusing on one thing, or on everything. The colors, and the lack of them.

Experience

Meditation

Calm, peace, content, equanimity. The sensations, the good and the bad. It is what it is.
