Products and platforms I've taken from zero to production

Co-Founder & CTO — 2024–Present

An entire real estate business,
in one platform.

Admin property view

Everything you need, where you need it.

Manage your properties, listing types, and campaigns — all the tools to close more deals, in one place.

Lead expedition with AI

AI as your business partner.

More than a tool — a teammate. Get notes, suggestions, strategies, and manage your daily agenda and schedule without switching apps.

Advisor profile settings

Make it yours.

Customize every detail of how you use Yauz — schedules, availability, your plan, and personal preferences. Work exactly the way you work best.

Landing page

Designed to feel familiar from day one.

We obsessed over every interaction to make the interface friendly, intuitive, and accessible — so advisors actually use it.

The Challenge

What I Built

Six layers. One system.

Every feature was designed around a single truth: advisors spend too much time on admin and not enough on people. Each layer removes friction from a different part of their day.

01Core

Property Management

A 7-step listing wizard covering media, pricing, location, and status — everything publish-ready in one structured flow.

02AI

AI Lead Intelligence

Amazon Bedrock-powered scoring, next-move recommendations, and quality predictions. The CRM thinks ahead so advisors focus on closing.

03Integrations

WhatsApp Automation

Meta API integration for automated, context-aware client conversations and lead follow-up — in the channel advisors already live in.

04Data

Analytics Dashboard

Real-time pipeline metrics, listing performance, conversion rates, and advisor activity — all visible in a single command center.

05Product

Property Portal

A public-facing portal for buyers and renters — search, filters, map view, and a marketplace of home services beyond the listing.

06Core

Agenda & Scheduling

Full calendar with availability management, appointment booking, and automated reminders across the advisor's full week.

The Portal

Not just for advisors. For everyone looking for a home.

The portal is the bridge between advisors and the people they serve. Buyers and renters find properties — but also everything they need around the transaction: movers, carpenters, locksmiths, cleaning services, valuations, and more. Yauz is not just a CRM. It's the operating system of real estate in Mexico.

"Real estate doesn't end at the keys. We're building everything that happens before, during, and after."

Vision · 2024

Technical Direction

Led a second engineer from onboarding to production — defining architecture, setting standards, reviewing every PR, and making sure the portal shipped without breaking the ecosystem.

Full Ownership

Every decision — from AWS infrastructure to pixel-level UX — was mine to make. Built as an engineer, led as a CTO, shipped as a founder.
