• Environment: Leading a whole company
• Methodology: Scrum, Continuous Improvement, DevOps
• As the founder and Key Technical Architect at Hôbud, I drove the critical developments that enabled the implementation of a unique data resilience solution. My role involved designing a peer-to-peer (P2P) backup system integrated with geolocation and coupled with a mobile application, ensuring complete data sovereignty.
• To guarantee maximum security, I implemented airlocks (security sashes) to control and isolate data flows between the internal network and external environments. This approach minimized exposure to cyber threats while maintaining seamless data synchronization.
• Additionally, the solution leveraged containerization (using technologies like Docker and Kubernetes) to ensure scalability, portability, and efficient resource management. Containers allowed us to deploy the backup system across diverse infrastructures while maintaining consistency and security.
