Hi everyone 👋

With over 20 years in the tech industry, I started as a software developer, crafting solutions for telecom and financial sectors. My evolution from developer to software architect enabled me to design robust, secure software solutions, leading me to a specialized career in cybersecurity.

Know a little bit about me

Quick overview

What I do

Currently, I lead the cybersecurity efforts at Mercado Livre, focusing on safeguarding our crypto asset products. I've played an important role in the Open Finance Brazil initiative, co-authoring the Security Profile that established foundational security policies across the open banking ecosystem.

My academic background includes a Master’s in Tech Innovation from Universidade Federal de São Paulo, where I explored blockchain-based digital identities for healthcare. I also hold a Bachelor’s degree in Computer Science from Universidade Metodista de São Paulo.

As a freelance teacher, I share my knowledge of Cybersecurity & Cyberlaw with MBA students, constantly exploring tech's impact through my YouTube channel and podcast.
