I contributed to the development of a decentralized data sharing and governance platform, designing user interfaces and implementing core server-side features. The system uses Keycloak for role-based access control and certificate-based authentication to enable secure machine-to-machine communication.

In collaboration with energy experts, I developed a customer portal for energy communities in Slovakia. The platform enables users and administrators to manage communities, share energy, and handle transparent billing for energy production and consumption.
