Founded and led Rede Sky for seven years, combining hands-on software engineering with technical leadership and business operations. Grew the platform to more than 16 million registered accounts, 300,000 monthly active players, and a peak of 8,115 concurrent players. Rede Sky ranked as Brazil’s largest Minecraft server by online player count for four consecutive years.

• Architected and developed scalable Java systems supporting thousands of concurrent players across an extensive portfolio of custom game modes, with a focus on low latency and fault tolerance.
• Led development of a game mode built on distributed architecture, enabling more than 1,000 players to interact within a shared virtual environment.
• Built and maintained hundreds of custom plugins powering matchmaking, gameplay logic, anti-cheat systems, virtual economies, and real-time events.
• Led the development team and established architecture, CI/CD, and engineering workflow standards across more than 250 Git repositories, primarily in Java.
• Automated infrastructure operations with Bash and implemented monitoring and error tracking with Grafana and Sentry to support production reliability and troubleshooting.
• Directed business operations, growth strategy, and community engagement, connecting player feedback with technical priorities and the development of new game experiences.

At 14, I started Mineland Network with friends, turning our enthusiasm for Minecraft into a community that grew to more than 500 concurrent players across five custom game modes.

This was where I first learned Java and the fundamentals of programming, building features that people played every day. It was also my introduction to web development, running an online store selling VIP packages and virtual currency, and working with content creators to bring new players to the server.

Behind the scenes, I learned to use Linux through the terminal and set up a dedicated server to host our games, website, databases, and supporting services. Working alongside friends, I got my first experience with everything involved in building, running, and promoting an online product.

Mineland was the first time I earned money from something I helped build. Seeing hundreds of people enjoy what we created together made a lasting impression on me and laid the foundation for my career in software engineering.
