My part

Helped develop the idea, spoke with the judges, presented the pitch and assessed its viability; kept following it after the event, including meetings with lawyers.

Tradeoff

Make a recurring donation feel understandable without hiding the donor choice behind a checkout default.

Evidence

Public winner post, team and event photos, and the prototype landing screen.

Research before interface

We spoke with NGO teams and donors about repeat giving. Small recurring amounts were easier to accept than another monthly campaign.

The proposed mechanic

Vueltito rounded an ecommerce purchase and assigned the difference to an NGO selected by the donor. We designed the plugin concept and donation flow during the event.

I presented the project to the judges and kept assessing its viability after the hackathon, including meetings with lawyers. Our team won the Paisanos NGO hackathon; the linked public post documents the result.
