Real estate operator & AI product builder

I work in acquisitions and AI operations at PrimeSpace Capital, where I build internal tools for underwriting and accounting. I’m also building Feature.graph, the development environment I use to ship software.

PRIMESPACE CAPITAL

Internal tools & AI adoption

People at PrimeSpace come to me every day with workflows that need fixing. I scope the problem, build the tool, and help them use it. My internal tools are used by 15+ team members, replacing manual processes and reducing third-party software spend. Below are three workflow tools and the firm-wide AI rollout.

Underwriting

Pricing report pipeline

OneDrive-synced PDF reportsStructured comparable pricing

Competitive pricing arrived in PDF reports. I built a pipeline that ingests those reports from OneDrive and produces structured comp data for the underwriting workflow.

What changedReplaces manual extraction of pricing from PDFs with a repeatable report-to-data pipeline.

Acquisitions research

Market data integration

TractIQ APIOwnership, pipeline & supply data

I integrated TractIQ ownership, development pipeline, and supply data directly into the underwriting workflow.

What changedRemoves the separate lookup-and-copy step for ownership, pipeline, and supply research.

Accounting

Journal Entry Builder

CubeSmart financial spreadsheetsInternal journal-entry workbook

Monthly property-manager financials need to be translated into the firm’s accounting format. I built a tool that maps CubeSmart spreadsheets into the internal journal-entry template.

What changedReplaces manual reformatting of property-manager financials with a generated workbook ready for accounting review.

Firm-wide AI adoption

Claude Team rollout

Team workflows & recurring tasksShared workflows & trained teams

I evaluated and deployed Claude Team across the firm, standardized workflows that worked, and trained teams to use them.

What changedTurned individual AI experiments into shared workflows that teams could repeat and adopt.

These examples describe internal workflows. Source code and company data remain private.

CURRENT PERSONAL PROJECT · MAC DESKTOP BETA

Feature.graph

A development environment for working with Claude Code and Codex: map a codebase, propose a feature, run the implementation, and review the change before keeping it.

I use Feature.graph for all my coding.

Feature.graph mapping its own source repository into product capabilities
Feature.graph on its own repository · Focused map · 120 features, 187 files · Open full size →
  • A product map groups source files into capabilities so I can navigate the application by what it does.
  • Claude Code and Codex run alongside the terminal, app preview, and GitHub state.
  • Each proposed change has an implementation and review workflow, with separate keep, discard, and push actions.

About

My background is finance and real estate. Working inside an investment firm gives me direct exposure to the spreadsheets, reports, and repeated tasks that software can improve.

I use coding agents extensively. My role spans deciding what to build, defining the workflow, integrating systems, reviewing the result, and getting people to use it.

Feature.graph grew out of that development workflow. I’m building a way to keep product decisions and agent-generated changes visible as a project grows.
