Senior Full Stack Developer at Demia building Rust services for an operational data platform and distributed network.

Spain

Message

At Demia, I develop software across an operational data platform, including Rust services for accounts, organizations, sensors, readings, and data-processing workflows. I integrate cloud services and authentication with PostgreSQL, MySQL, and Redis, and connect the platform to a self-hosted distributed network.

At IOTA Foundation, I contributed to early IOTA node software and developed IOTA Streams for encrypted data sharing. I also built client libraries exposing a core Rust library to Java, JavaScript, and Python; at Pangea Chat, I established the initial application and later led server-side development while taking on a part-time CISO function.
