Available · Product Marketing Manager · 2 iOS apps shipped · Asbury Park, NJ · remote

Indie developer who has built 2 apps and instrumented them end-to-end in Mixpanel, running onboarding conversion experiments to find the flow that turns installs into paying users. Before that, nine years of product work as a cofounder, COO, and chief of staff, scaling new and existing products, including a K-12 education company I helped grow from one location to five nationwide, 1,000 students, and $1M in revenue before it was acquired.

Things I took from zero to one

From communicating the complex topics within the IRA to building apps, I am passionate about creating products that provide people with real value in their daily lives.

What brings me here

I’ve spent the past four years as a VPP cheerleader, DER enthusiast, and microgrid nerd. It would be amazing to contribute to your mission and help harness millions of distributed energy resources and build a cleaner, more reliable power system. I would love the opportunity to build alongside your team at EnergyHub.

Become an expert on customers and the challenges they face around DER adoption
My illustrated guide to the Inflation Reduction Act came from sitting inside exactly that challenge: rooftop solar, battery storage, an EV on a charger, heat pumps, a smart panel, and a homeowner who could not tell which incentives were theirs. 250,000 impressions, and local governments adopted it as their explainer for residents.

Lead the creation of marketing collateral, including case studies and sales enablement materials
This portfolio is the collateral: five case studies, an App Store listing I wrote and iterated, and a dashboard built to show what converts and why. Free Time’s trial-to-paid runs 61.6% all-time across 426 days tracked. Case 02 →
Distill complex concepts into clear, compelling messaging in simple, everyday language
Unplug OS asks someone to give up their smartphone unless it is plugged in. I specified the onboarding as a 24-screen, three-act narrative, because a hard ask has to be explained before it can be accepted. Twelve versions before a line of production code. Case 03 →
Measure and analyze the effectiveness of marketing initiatives, and act on what you find
I built one dashboard joining Mixpanel activation, RevenueCat subscription state and App Store Connect acquisition, because no single tool could tell me which channel, listing, or message actually converted. Case 02 →
Collaborate cross-functionally with Product, Sales, and Client Success to refine messaging
At Dashboard.Earth, a consumer climate app, I developed the OKRs and built the process that let product, design, operations and leadership talk to each other, managing a cross-functional team of 10 on a $1.6M Rockefeller Foundation budget.
Passion for sustainability, renewable energy and driving positive environmental impact
I have built an audience of 55,000 around climate work from zero, reaching more than 3 million people by continuously testing what format and message actually landed, worked directly with scientists and policy experts at DOE, RMI, Harvard and MIT, and run an open-source database that helps people find climate jobs.
