Introduction

Technical precision, human perspective

I work in software quality with attention to context, risk, and collaboration. Outside work, I make room for learning, reading, and culture.

The first step toward wisdom is to fear the Lord. To know the Holy God is to have understanding.

Proverbs 9:10
Quality is never an accident. It's always the result of intelligent effort.

Personal notes

Worship & Consecration
Constant pursuit of the Lord, reading His Word and praising Him.
Books & Learning
Bible reading, The Psychology of Money, The Intellectual Tool Kit of Geniuses, Clean Code. Reading is always an enriching source of knowledge.
Places & Culture
I love our country, I had the opportunity to travel through some Brazilian states and I like them very much: Minas Gerais, Rio Grande do Sul, Rio Grande do Norte, Goiás, Bahia, and Espírito Santo. I want to know even more!
Games
Nostalgic games: Street Fighter, Mortal Kombat (I, II, III, and Trilogy), Super Mario World.
