Prepared for CoStarSenior Product Manager · Underwriting Specialist
I build tools around the questions a credit team actually has to answer: what changed, what supports the number, what breaks under stress, and where a person needs to decide.

Built from the lender’s side of the desk
My background spans commercial real estate, commercial lending and homebuilder finance at Flagstar. These projects show how I approach product design: explicit assumptions, traceable calculations, useful defaults and clear boundaries for automation.
Selected work
Start with Bridge for the most direct CRE example.
Each project includes a short review path on GitHub.
CRE underwriting → stress → credit review
A multifamily credit case that connects deal assumptions, underwriting metrics, stress scenarios and a reviewable recommendation.
Change an underwriting assumption, run a downside case, and inspect how the credit review responds.
Portfolio surveillance with an evidence trail
A recurring review workflow that turns a structured workbook into an executive QPR, material changes, source lineage and a downloadable PDF.
Load the fictitious demo, inspect a source behind a headline metric, and review the PM narrative controls.
Compare structures before committing to one
A scenario workspace for homebuilder lending, with timing, liquidity, collateral and structure comparisons grounded in a monthly calculation model.
Change a scenario, compare structures, and follow the cash-flow impact into the supporting detail.
Agreement rules + collateral evidence + exceptions
The collateral project’s deterministic engine and scaled synthetic portfolio, presented without a login or connected borrower systems.
Reduce an advance rate, remove a required source, then explore source conflicts across 2,400 fictional units.
From evidence and PM judgment to a Word memo
A browser-based credit drafting workspace with source analysis, explicit judgment inputs, draft review and Word document output.
Open the guided workflow, explore the example, and see how evidence and authored judgment stay separate.
A research product, with methodology you can inspect
A homebuilding market-intelligence project built around source provenance, repeatable scoring, historical validation and controlled publication.
How do you turn fragmented market evidence into a research product people can challenge, trust and use repeatedly?
An alternative if your network blocks the demos
Project walkthroughs and screenshots are available without the demo site. A downloadable browser demo pack is included for local review.
