I believe the best developers don’t just build impressive things, they understand why that work matters to the business. I spent years on both sides of that wall: writing code, managing editorial systems, and defining technical architecture. For me, the gap between “technically correct” and “strategically useful” is exactly where I’ve spent the last 25 years.

Today I work as Platform Owner and Tech Lead at Black & White Zebra Inc., where I lead cross-functional work across engineering, design, content, and marketing, translating business priorities into systems that actually ship and deliver value.

Before stepping into platform leadership, I served as CTO at Hubee, where I defined the full technical architecture of a SaaS platform built on PHP, TypeScript, React, and Next.js. Earlier, at Agência Moustache, I led development for clients including XP Inc., Volkswagen Brazil, and the Banco 24 Horas. I engineered content systems, led performance audits, and owned the technical handoff process. I also founded VisiteFoz, a tourism platform that grew to more than 10 million visits over its lifetime.

I hold an MBA in Software Engineering and a Specialization in Artificial Intelligence, both from UTFPR, and I am currently completing a Specialization in AI and Automation at Rocketseat. I also hold an MBA in Full Stack Development from XP Educação, a technology degree in Digital Games from Universidade Positivo, and an academic-honors Bachelor’s Degree in Advertising and Marketing from ESPM.

I enjoy creating experiences that enable people to interact with computers through compelling user experiences. It doesn’t matter whether it’s a game or a content page; in the end, the interaction with the computer rests on the same fundamentals: trust, recognition, energy, action, and reaction. Thinking about technology through this lens is how we connect with real people.

My areas of expertise:

  • Software engineering
  • Game design and development
  • Web development
  • AI

More About Me:

When I am not shipping features, reviewing PRs or thinking about products, I am probably building a game. I’ve been developing indie games both solo and with small teams since 2017 under the Gruhh Games project. Several of my projects have earned official selections and honorable mentions at SBGames, Brazil’s largest academic game conference.

What’s in My Tech Stack:

  • Development IDEs: PHPStorm, WebStorm, Bruno
  • AI Platforms: Claude Code, Anthropic Ecosystem, and Google Gemini
  • Web Development Platforms: Next.Js, WordPress, Drizzle, Coolify
  • Game Development Platforms: Unity 3D, GameMaker, Construct, Unreal Engine, Blender, Aseprite
  • Communication Software: Slack, Notion, Fastmail
