One leader for the data, the systems, and the team

I build and run data, AI, and technology functions, then use them to automate the manual work slowing a business down. At McKinsey & Company, I own platform operations, data governance, and engineering delivery for a 100K+ institution data platform, and I build the AI agents and automated workflows that run on top of it.

Before that, as a Director and Senior Manager, I owned data governance, BI, and core business systems: platform vendor management, budget, release cycles, and a hands-on analyst team. Most of that was inside industrial and manufacturing environments (Johnson Controls/Clarios, IEWC, Navistar), including two years partnering directly with plant maintenance teams on the shop floor.

I also spent 24 years in the Army National Guard, including two combat deployments, and commanded 106 soldiers.

What's next: a company small enough that one leader can own the data, the systems, and the team, and turn them into results a CFO can see.

02 / Selected Work

Built, run, and measured

Six things I have owned personally. Each pairs the scale I have worked at with the scale I actually operate at: the team, the budget, the days saved.

01
Built and led a data, BI, and technology team at IEWC.

Owned hiring, coaching, and a $1.5M+ annual budget. Personally owned platform operations and vendor management for the BI platform (Qlik, cloud-hosted) and the product master data platform (Stibo STEP), including cost, patch and release cycles, and enhancement roadmaps. A 3-person analyst team under me served as the business's first line of technical support for BI and data issues, and I took help desk calls myself when needed.

02
Automated manual, people-heavy workflows end to end.

At IEWC, owned the master data and integration workstream (customer data plus the PIM product master) on a Salesforce CPQ implementation that cut quote turnaround from 3 days to 6 hours. At McKinsey, identified and led an agentic automation of a fully manual, Excel- and email-driven onboarding workflow supporting 145+ client communities: cut time to activation 38% (58 to 36 days) and triage effort 94% (90 to 5 minutes per request).

03
Partnered directly with plant maintenance teams across multiple manufacturing facilities.

For two years at Johnson Controls, owned indirect-materials master data governance and worked hand in hand with plant maintenance and PMO teams. Led the data migration into a new plant maintenance system with data quality controls built in at the point of entry. Replaced an informal, plant-to-plant phone network for locating spare equipment ("does plant A have this in stock?") with real-time, cross-plant inventory visibility, so plants could transfer high-cost spares instead of buying duplicates.

04
Advised C-suite leaders on data and AI investment priorities in commodity-driven, capital-intensive businesses.

At a $6B+ energy company, decomposed data and AI requirements into a domain-driven framework that included the data products behind a near-real-time commodity pricing optimization model. The resulting strategy secured funding for a $300M+ project portfolio and cut data discovery time 62%.

05
Built AI agents that are in daily production use.

Architecture lead for the semantic layer inside an AI research agent on Snowflake Intelligence (wrote the semantic model and SQL myself). Built an AI agent with Cursor, Claude Code, and MCP integrations that automated a manual data-verification workflow: each record is auto-classified as verified, an issue with a recommended fix, or low-confidence and routed to an analyst, cutting a multi-day review to a few hours. Human-in-the-loop review and governed data access are built in from day one.

  • Daily production use

06
Built a data governance function from zero at a $10B+ financial institution.

Designed the governance operating model and target-state data organization, presented it to the COO and CFO, and it became the structure the firm adopted and hired against. Foundations first: this is the groundwork an early-stage data program needs before AI can be trusted.

04 / How I Work

Operating principles

These are the patterns behind the work above. They are what I would bring to a mid-market manufacturer early in its data and AI journey, with an ERP program in flight and a CFO who wants results, not a strategy deck.

  1. 01

    Foundations before AI.

    The first job at an early-stage data organization is data quality, master data, and a governed warehouse. AI that runs on bad data produces confident nonsense. I have built this foundation from zero twice (a $10B+ institution and Johnson Controls' first data governance function) and inside an ERP program (SAP MDG at Johnson Controls).

  2. 02

    Automation starts with the workflow, not the tool.

    The onboarding automation, the CPQ integration, and the verification agent all started the same way: stakeholder workflow discovery, then a written spec, then a build with human-in-the-loop exceptions. It is the same pattern for AR cash application, order processing, and headcount reporting.

  3. 03

    Hands-on at the right altitude.

    I write the SQL for a semantic layer, answer the help desk when it is needed, walk the plant floor with maintenance teams, and still present investment cases to a CFO. A smaller company needs one person who can do all four.

  4. 04

    Working with vendors you don't control.

    I owned the Qlik and Stibo STEP vendor relationships at IEWC and worked inside a bespoke industry platform at a financial services client whose roadmap did not always serve its customers. I get results inside constraints rather than around them.

  5. 05

    Leading people through change.

    Military command of 106 soldiers - two combat deployments, cross-functional groups of 10 to 15, and a focus on coaching and developing team members through 360 degree feedback. I plan for skeptical, tenured teams and earn trust by delivering.

Road cycling and gravel riding keep me balanced. Covering miles under your own power clears the mind and builds resilience.

Sports Fishing

Time on the water is time well spent. Whether fly fishing a stream or chasing bass, it is where I recharge and find perspective.

Helping young athletes develop their skills and love of the game. Leadership is not just in the plant or the boardroom; it is on the diamond too.
