About

I hold the Brazilian investment visa through property ownership, am currently working on my fifth acquisition, and am developing residential projects in Rio de Janeiro.

The technology work I do for real estate clients is informed by operating in the same market as they do. Because I understand what real estate professionals actually need from the operator side, I build better systems for them.

My clients are typically individuals or small teams, running serious operations lean. I work the same way.

The portfolio is the day job. The technology comes from being in the room.

What I do

  1. 01

    Investing

    Acquiring residential and small commercial assets in strategic locations, held for cash flow and patient appreciation.

  2. 02

    Development

    Vintage stock refurbishing & redesign, run lean with local trusted partners. Anticipating design trends cuts time-to-lease.

  3. 03

    Tech & Research

    Building the backend operators in this asset class actually use. Workflows informed by leasing data and a close read of where design culture is going.

    New residential pipeline, Butantã

    Butantã's proximity to Linha Amarela metro and USP is driving a wave of new launches. Mitre Realty's Raízes Premium Butantã (Rua Santa Rosa Junior) offers studios to 115m² units across three towers; Trisul's Elev Butantã on Av. Vital Brasil targets compact 25–38m² units steps from the metro; and Diálogo Engenharia broke ground in mid-2025.
