Selected work

Problems I've solved, and how.

Three examples of owning the path from ambiguous operational data to governed analytics systems. Names and sensitive details remain intentionally limited.

  1. AdeptID · 2026 · Analytics engineering / BI

    A governed headcount model for executive recruiting decisions

    Replaced a hand-built executive workbook with a governed dbt semantic layer, giving Finance, Operations, and leadership one definition of recruiter headcount.

    Outcome: Every downstream report now uses the same definition.

  2. AdeptID · 2026 · Analytics engineering / Data platform

    A metric layer that can explain the past as well as the present

    Took a canonical library of 50+ company metrics into the warehouse and built point-in-time history for reproducible period reporting.

    Outcome: Executive reporting now runs on governed views.

  3. AdeptID · 2026 · Analytics engineering

    A measurement contract for an AI matching product

    Defined and modeled the validated outcomes behind product-performance reporting, with shared rules across Product, Engineering, and Finance.

    Outcome: A validated fact table ready for product reporting.

Experience

From implementation to analytics ownership.

Seven years progressing from client data systems and revenue analytics to governed metric layers, warehouse architecture, and executive decision support.

Core toolkit

How I work

A trusted metric is a system, not a number.

Business question → metric definition → warehouse logic → QA → BI experience. Each step makes the next one more reliable.

  1. 01

    Define

    Write the metric contract: owner, grain, rules, and the decision it supports.

  2. 02

    Model

    Make reusable logic versioned, reviewable, and available beyond one report.

  3. 03

    Validate

    Use source parity, structural checks, and stakeholder review before release.

  4. 04

    Deliver

    Expose a governed answer where people make decisions.

Independent projects

Public experiments in decision support and data visualization.

A small collection of work that demonstrates techniques and questions I cannot show from client systems.

About

From maps to metrics.

Boston, MAWorking at the intersection of systems and people

I studied geography at UMass Amherst, and I still approach data the way a cartographer approaches a map: it should be accurate, honest about what it leaves out, and readable by someone who was not in the room.

My work moved from client data implementations to revenue analytics, geospatial systems, and analytics engineering. The common thread is understanding complicated systems and making them understandable enough to act on.

I use AI coding tools to move faster, and I verify every result before it ships.
