Launched Builder Showcase, Zillow’s premium tier for homebuilders

0 → 1

net-new product tier

Problem

Zillow needed a premium listing tier for homebuilders: a net-new product that also had to integrate with the legacy builder reporting system.

Approach

Led engineering from design through production. Architected the backend proxy and auth layer that integrated Showcase with the legacy builder reporting dashboard, and built reusable micro-frontends that accelerated delivery on zillow.com and in the dashboard.

Outcome

The pilot far exceeded its sign-up target, and the same micro-frontends went on to power New Construction in Zillow’s ChatGPT app.

CASE STUDY 02 · ZILLOW · DATA

Halved Flink infrastructure cost

−50%

Flink infrastructure cost

Problem

Four Flink jobs each ran redundant scans over millions of daily records, on CPU and memory allocations that left capacity idle.

Approach

Added an upstream filter so the four jobs no longer scanned the full stream, then rightsized CPU and memory to peak-load metrics.

Outcome

Flink infrastructure cost dropped 50%.

CASE STUDY 03 · J.P. MORGAN · PAYMENTS

Cut the FX payments release window from 6+ hours to under 1

6h → <1h

weekend release window

Problem

Weekend production releases of the FX payments platform were manual, error-prone and took more than 6 hours.

Approach

Wrote custom Unix deployment scripts that automated the release and removed the manual steps.

Outcome

The deployment window fell from over 6 hours to under 1.

AI-augmented engineering

AI-assisted development as a daily workflow, not a novelty.

At Zillow I led the New Construction experience in Zillow’s ChatGPT app, extending the Showcase micro-frontends so we were the first team with a working integration. Outside work I build with Claude Code, and getPaged.ai uses Claude to pull job details out of inbound calls.
