Marcin Trochimiak

Principal Workday Architect & Data Conversion Automation Expert

I am a strategic Workday Lead Architect specializing in high-stakes Data Conversion, Financial Data Model (FDM) optimization, and Phase X implementations. I help global organizations transition complex legacy data into Workday seamlessly. By combining deep architectural knowledge with custom automation (Python/AI), I eliminate manual data-entry risks, reduce project timelines, and ensure 100% SOX compliance during configuration migrations.

Core Competencies

Strategic Solutions

Automated Data Conversion & Integration

Moving beyond traditional, error-prone manual Excel mapping.

Building automated ETL pipelines (using Python, pandas, and XML generation) to process massive datasets from legacy systems (SAP, Oracle) directly into Workday EIBs and Advanced Loads.
Eliminating manual data correction bottlenecks to accelerate deployment timelines and ensure data integrity.

Phase X Configuration Migration Strategies

Providing tailored configuration extraction and migration approaches based on client risk profiles and business continuity needs:

The Blueprint Approach: Utilizing Implementation Suites for full XML iLoad extraction during major country rollouts or module rebuilds.
The Surgical Approach: Leveraging Change Tracker and Object Transporter (.dat files) for precise, fully auditable, and SOX-compliant functionality migrations into production.
The Dynamic Data Approach: Building Workday Studio integrations (Get_References) to automatically generate weekly Excel extracts (Record Names, WIDs, Reference IDs) to secure a "Single Source of Truth" for functional teams.

Financial Data Model (FDM) & Enterprise Architecture

Designing the core nervous system of Workday. Aligning Cost Centers, Companies, and Custom Worktags to ensure flawless downstream impacts across HCM, Payroll, and Financials. Acting as a trusted advisor to C-level stakeholders to translate business strategy into scalable system architecture.
