Product engineering for complex workflows.

I build software that turns scattered data and business rules into tools people can understand and act on. Applied AI is a specialization: I use it within workflows that keep decisions inspectable and people in control.

Quarry job board with application stages and explained match scores
Quarry assistant proposing a configuration change for review

A job-search workflow with explainable matching and AI proposals that change nothing until approved.

  • Conversational changes become reviewable configuration diffs
  • Matching explains requirements, uncertainty and qualification gaps
  • Saved decisions survive discovery and configuration changes
  • TypeScript
  • Next.js
  • PostgreSQL

Control Center budget versus actuals for individual projects

An IT portfolio workbook rebuilt as a snapshot-based web application with role-checked editing.

  • Budget, actuals and remaining forecast stay distinct
  • Snapshots preserve financial and portfolio decisions over time
  • Reconciliation exposes differences between PMO and Accounting
  • React
  • FastAPI
  • PostgreSQL

Turning Meaning into Metrics

AI can work with language. The harder engineering problem is making a request mean the right thing inside a particular domain.

Magic makes that problem concrete. A card’s meaning depends on its rules, timing, game state and interactions with other cards. A semantic ontology defines a domain’s entities, concepts and relationships. I’m exploring how to use one to connect card language to facts, constraints and executable behavior.

Ground the facts. Model the behavior. Evaluate the decision.

Build under constraints. Close the feedback loop.

Where the research comes together

Deck Lab is the application layer: card research, deck editing and supported analysis in one workflow. The direction is to bring domain facts, semantic interpretation and decision tools together in a product people can use.

A competitive Commander research and deck-editing workbench built around explicit data and service boundaries.

  • Tournament research connects aggregate metrics to sample sizes
  • Interactive deck editing shares versioned data and service boundaries
  • Simulation labels its supported scope and modeling limitations
