Technical pieces of Workday, done without the firm.
Seekers LLC is the independent practice of Colin Frederickson, a Workday Technical consultant with eleven years of enterprise HRIS migrations: data conversion, integrations, and reporting across HCM, Benefits, Payroll, and Financials. Direct engagement, no layers, no handoffs.
Three pillars of Workday delivery.
Data conversion
Worker, position, supervisory, benefits, payroll, and financial data converted from Lawson, Kronos / UKG Pro, SAP, PeopleSoft, ADP, NetSuite, PayMode, and Concur. Effective-dated logic, dual employment, dependents, beneficiaries, YTD balances, suppliers, and FDM crosswalks. EIB and LoadAPI delivery with full reconciliation reporting.
Integration architecture
Inventory, scope, and design of inbound and outbound integrations across HCM, Benefits, Payroll, and Financials. Tool selection across EIB, Core Connectors, and Studio. Data flow design, vendor handoffs, and integration specs that hand cleanly to a build team.
Reporting architecture
Reporting and dashboard strategy across HCM, Benefits, Payroll, and Financials. Tool selection across calculated fields, matrix reports, BIRT, and Workday Prism. Audit, reconciliation, and dashboard frameworks scoped, designed, and managed to delivery.
Recent and current client work.
Academic medical center, multi-population conversion
Lead data conversion across HCM, Benefits, Payroll, and Grants for a Fortune 500 academic medical system. Brought multiple legacy populations to a unified Workday state: supervisory org alignment, comp effective dating, and dual employment remapping across pipelines. Rebuilt the end-to-end conversion process to incorporate secure, thoughtful use of AI.
Specialty healthcare, multi-entity supply chain conversion
Workday SCM and Financials conversion for a regional orthopedic specialty group spanning three operating companies and five inventory populations. Built a Python framework that consolidates legacy item, supplier, and stocking-location data into a single de-duplicated item master, with cluster-duplicated PAR locations, dynamic location config, and Patient Charge Information generation.
Workday Financials implementation, supplier workstream
Supplier data conversion across NetSuite, PayMode, and Concur for a national insurance brokerage. Python framework for cost-center mapping, bank validation, and duplicate review.
Multi-population HCM conversion & integration inventory
Data conversion across legacy and new entity populations for a major family entertainment group. Integration inventory management and contingent worker conversion strategy.
UKG to Workday migration, governance lead
Data governance framework for a national asset manager's UKG-to-Workday migration. Delivered a tenant-wide gap analysis with a recommendation and implementation handling guide for every gap, plus field-level mapping across payment elections, tax elections, and service dates.
Engineering discipline applied to enterprise data.
The work is straightforward in theory and unforgiving in practice. Conversions live or die by what's in the source. Integrations succeed or fail in the white space between systems. Reports earn their keep in the audit. The hard part of Workday isn't the configuration. It's the legacy fields no one remembers being added, the effective-dated quirks, and the cross-functional touchpoints that nobody else sees.
Seekers brings a build-it-properly-once sensibility. Standardized extracts, transformations under version control, baseline snapshots and diff queries for testing. Architecture decisions captured in writing (what tool, what flow, what handoff) so build teams don't have to guess. AI used thoughtfully and securely to compress the boring parts and free time for the parts that need judgment.
Engagements run direct with the client. No staffing pyramid, no handoff between sales and delivery, no surprises in the second invoice.
