I was instrumental in the creation of a platform featuring games designed to develop cognitive skills. This project aimed to provide engaging,
interactive experiences that supported mental agility and learning, blending game design with cognitive science principles.
Responsibilities:
• Designed and maintained the architecture and business logic of the platform's core features.
• Designed user interface architecture to support modularity, scalability, and maintainability.
• implemented complex, containerized user interfaces, focusing on dynamic layout management, modularity, and reusability across
components.
• Implemented robust communication with the backend via REST API and Web Sockets.
• Developed and integrated a cross-platform notification system using Firebase Cloud Messaging (FCM), supporting Android, iOS, and
desktop platforms.
• Integrated and managed deep linking across platforms, allowing for seamless navigation from external sources into specific parts of
the app.
• Ensured scalability and modularity of the system for future expansion and easy onboarding of new games and features.

Additionally, i played a key role in the development of a medical project focused on endoscopic surgery, where I played a central role. My
contributions were pivotal to the project's success, guiding it from its initial stages through to its completion, ensuring that the product and
used technologies were effectively integrated and optimized for medical use.
Responsibilities:
• Designed and supported a State Machine driven architecture.
• Developed and maintained core features.
