INITIATIVE :: COMMUNITY

NextStack Academy

FounderDeveloper Community

I created NextStack Academy as a place where developers can learn from each other, share technical knowledge, exchange ideas and build projects together. It is centered on practical collaboration and communication between programmers.

Long-term vision

Grow toward an international community that connects developers from different backgrounds.

  1. Learn Together

    Learn through shared knowledge and technical experience.

  2. Build Together

    Turn ideas into projects through real collaboration.

  3. Communicate

    Create space for questions, feedback and useful technical discussion.

  4. Grow Together

    Improve engineering skills through practice with other developers.

MODULE :: ABOUT

About Me

I’m a Full-Stack Developer from Brazil focused on building practical web systems for real businesses. My work spans backend and frontend development, databases, deployment and infrastructure, with security considered from the start.

I work on paid client projects and currently mentor six students, helping them understand how software is designed and built rather than simply copying code. I continue developing my engineering skills through production work and formal Computer Science study.
