What I Do

Comprehensive Workday Services

Every service is built entirely around Workday, the only platform this practice touches.

01

Workday Extend

Built and deployed Extend apps handling real production workloads, including a contingent-worker onboarding app at Carvana automating 30+ onboardings a month.

02

Orchestrations

Event-driven, multi-step automations. At Carvana: 5 Orchestrations automating HR/IT events across Workday, ServiceNow, and payroll, durable and auditable.

03

Implementation

End-to-end HCM and Financial configuration, integration, and UAT. 16+ full-cycle implementations across six industries, with training and documentation.

04

Integrations

Studio, Core Connectors, EIBs, RaaS, PECI/PICOF, Cloud Connect. Delivered for populations up to 80,000+ workers with Listener Service and MQS.

05

Workday Studio

Production XSLT 3.0 streaming transforms for a 30,000+ employee payroll extract at Manulife, a scale where conventional processing wasn't viable. DART-clean, every time.

06

Custom Reports

Composite, Matrix, BIRT, and calculated fields, built for the decisions your leaders actually need to make.

07

Post Production Support

Go-live is the start, not the finish. Environments stay current, performant, and aligned as your business evolves.

08

Backfill Support

When your team is stretched, I integrate directly into your project: senior-level, no ramp-up curve, no junior bench.

What I've Shipped

Tools Built, Not Just Talked About

Three production tools, built to close real gaps in the Workday ecosystem. Evidence of the same execution this practice brings to client work.

Technical Depth

Rare Depth Most Workday Practices Don't Have

Five capabilities that separate this practice from generalist Workday consulting: all delivered in production, not theoretical.

MEM: O(1) vs O(n)

XSLT 3.0 Streaming

Traditional XSLT builds the entire source document in memory before producing output, a real constraint at 30,000+ employee scale. Native streaming keeps memory flat regardless of file size. Built for Manulife, delivered DART-clean.

$open xslt-sandbox
DELIVERY: exactly-once

Workday Message Queue Service

Guaranteed, exactly-once async delivery, even through downstream outages. Deployed for Nike, 3M, and Apple engagements (80,000+ workers), replacing latency-adding scheduled polling.

$open mqs-simulator
MODE: event-driven

Studio Listener Service

Event-driven inbound processing instead of scheduled batch jobs: near real-time data exchange with the systems Workday needs to talk to.

SCOPE: full BP replacement

Full-Stack Extend Apps

Two Carvana apps built fully in Extend: forms, orchestration, routing, and custom Business Objects, eliminating the double data entry a native-plus-Extend hybrid would have created. One automates 30+ contingent-worker onboardings a month; the other replaces a native Corrective Action process end to end.

SCOPE: 3 systems, 5 chains

Cross-System Orchestrations

5 production Orchestrations at Carvana spanning Workday, ServiceNow, and payroll: durable, auditable, multi-step event chains, not simple single-system triggers.

Why OTBIC

You Work With Me, Not a Delivery Team

02

A Real Engineering Foundation

13 years of full-stack software engineering (C#, .NET, JavaScript) before specializing in Workday: the reason the advanced-capability work is possible at all.

03

Certifications That Match the Work

9 active certifications, 8 Workday and 1 MuleSoft, covering Integration, Studio, Extend, Orchestrations, Financials, and Benefits.

04

Built to Last Post Go-Live

FAQ

Before You Reach Out

The questions procurement usually asks anyway, answered up front.

Are you working with other clients at the same time?

Sometimes. Capacity and fit are confirmed on the scoping call before anything is proposed, not assumed afterward.

What happens if you're unavailable mid-engagement?

There's no bench because there's no delivery team, that's the model. Planned time off is flagged in advance and built into the timeline, the same way any senior consultant handles it.

Can you complete our vendor security review?

Yes. Happy to complete your security questionnaire or vendor review as part of scoping, before any work starts.

How are engagements priced?

Hourly or project-based, whichever fits the scope. Confirmed on the first call, no surprises after.
