By combining visual impact with behavioral friction, it transforms security education into an engaging experience that encourages users to rethink password practices.

Enhance your digital world with this animation, keep your accounts hack-proof, and code with the same passion as EntroPy and DNAPass!

πŸ‘‹ Welcome to My Digital Universe

"Dive into the digital universe. Follow back or get out!"

I'm Gerivan Costa β€” a developer passionate about security, science, and creativity. Here you'll find projects that blend innovation with purpose, always focused on continuous learning and meaningful contributions to the open-source community.

My portfolio showcases cutting-edge tools like the Transformers Interactive Neural Network Visualizer, which demonstrates the future of information visualization through interconnected neural networks. This represents the next frontier in understanding complex data flows through artificial intelligence systems.

Explore innovative security solutions like DNAPass Password Generator, which bridges biotechnology and digital security by transforming DNA sequences into cryptographically secure passwords. This groundbreaking approach introduces biological encoding to password generation, creating truly unique and complex authentication systems.

Discover the EntroPy Password Generator ecosystem, featuring both Python CLI versions for Windows/Linux and responsive web implementations. The entropy-driven security model ensures maximum randomness and brute-force resistance by leveraging real entropy sources rather than predictable pseudo-random algorithms.

Did you like a project? 🌟 Give it a star! I consider it an incentive to keep learning, coding, and sharing with the developer community, because one idea generates another, even better idea!
