TENCHI SECURITY · 2025–PRESENT

Dashboard Redesign & UX Function from Zero

Brought in to build the UX function within a growth-stage cybersecurity company and embed structured design thinking into how the product is planned, built, and measured.

  • Built the UX function: scope, hiring criteria, and collaboration models across Product and Engineering
  • Designed and operationalized the company's design system, including governance and adoption strategy
  • Led redesign of primary product surfaces, reducing Customer Success overhead and improving prospect conversion during evaluation

PULL SYSTEMS · 2023–2024

EV Battery Health Platform

Porsche as lead investor and testing partner. Engineers were drowning in sensor data across disconnected systems. Designed the core analysis tools that turned data into conclusions.

  • Fleet event analysis: 6–9 months reduced to 3 months
  • Replaced manual spreadsheet workflows with structured visual interfaces
  • Benchmarked by a former Tesla engineer as surpassing Tesla's internal tools

CASCADE · 2022–2023

Strategy Alignment

Enterprise strategy platform. Large organizations had no way to see their full strategy as a connected system. Built the visualization that changed that, inspired by eight months hand-redrawing Vignelli's 1972 NYC subway map at full scale.

  • +17% time on platform
  • 10% churn reduction, identified as a conversion factor in new sales
  • Feature still in the product today

MERCADOLIBRE · 2015–2022

Checkout as a Service

MercadoPago was a collection of disconnected internal tools. Rebuilt the entire payment experience from scratch: modular architecture, every payment method, every country in Latin America, web, native iOS and Android.

  • 12% conversion improvement against a 1–2% target
  • 3 UX teams built from scratch across 7 years
  • Contributed to the definition of Pix with the Central Bank of Brazil

ABOUT ME

Pattern recognition as
design method

At six years old, I became fascinated with patterns: in buildings, in systems, in the order behind things. Not aesthetics. Structure. The logic that makes something hold together.

Design school gave that instinct a method. The design process taught me that any problem, not just visual ones, can be approached through structured exploration: understand the constraints, form a hypothesis, test it, adjust. That became the throughline of my career. Wherever there was friction, in interfaces, in workflows, in how teams talked to each other, I found myself doing the same thing: building the structure that removed it.

That's why the line between design and leadership never felt like a transition to me. Both are the same problem at different scales. I still open Figma every day. I also define team structures, run hiring processes, and align design decisions to business outcomes. The method doesn't change. The surface does.

Vignelli NYC subway map hand-drawn at full scale

The Vignelli map is probably the clearest example of how this works. I spent eight months hand-redrawing his 1972 NYC subway map at full scale, 120×150cm. Not as an exercise in draftsmanship. Because taking something apart at that resolution is the only way to understand how the decisions inside it accumulate into something that helps people navigate complexity without instruction. I own an original 1961 London Underground pocket map for the same reason.

These aren't hobbies. They're how I think.
