Career timeline

1994

First IT courses: DOS, Windows 3.11 and Novell networks. Part of a generation that built computers piece by piece, configured local networks and organized LAN parties, learning troubleshooting and systems logic along the way.

First personal computer: AMD K6-2 500 MHz. Technology stopped being just a hobby and became a professional direction.

2001 – 2004

Studied Psychology in Pouso Alegre, Brazil, while building websites, maintaining networks and providing technical support to local clients.

My Psychology background remains relevant: human behavior, cognitive biases and decision-making are direct foundations of performance marketing. In 2004, I made the definitive decision to pursue technology.

2005 – 2009

Moved to Curitiba. From 2008 onward, implemented ERP systems and business automation for bakeries and businesses across southern Brazil, with frequent trips between Curitiba and Florianópolis for system deployments, team training and integrations.

Participated in the weighing of the world’s largest bread in Curitiba, officially validated by Guinness World Records.

This period strengthened my project management, client relationships and understanding of business processes, providing a direct foundation for managing complex marketing operations.

2010 – 2013

Attended technology events (Locaweb and others). Identified an opportunity: there were many developers and infrastructure specialists, but strong demand for professionals able to generate traffic, audiences and growth for digital businesses.

Started studying SEO, Google AdSense, monetization and performance marketing. Curiosity became a specialization.

2014

Joined the e-commerce team at Multiloja, a company with more than 80 physical stores and annual revenue exceeding R$ 300 million. Worked on SEO, traffic acquisition and digital growth during a period of strong expansion in Brazilian e-commerce.

Made the definitive transition into digital marketing, focusing on metrics, performance and revenue generation.

2015 – present

Expanded into paid media, technical SEO, analytics, CRO, automation and business intelligence. Projects for companies such as Ford, Chevrolet, Santander, Willbank, Superdigital, DMCard, Multilaser and Stoodi, across fintech, automotive, e-commerce, education, technology, real estate and iGaming.

Today I work as an independent consultant through CM Consultorias and Radar do Marketing, focusing on Growth Marketing, Performance and BI for fintechs, real estate developers and technology companies.
