nBases — AI Platform for Mid-Term Rentals

Overview

nBases is an AI-powered platform helping remote workers evaluate mid-term rentals.

I created a Chrome extension with an AI scoring engine, then developed a SaaS for property managers to display these scores on their websites and optimize conversion rates. From there, I launched a lead generation engine connecting property managers with nomad guests—turning the platform into a two-sided marketplace.

Beyond the product itself, I handled the complete brand identity, designed and coded the website, and launched a social media strategy featuring AI character storytelling for community engagement.
