I'm David Viejo. I'm a blockchain expert and software engineer based in Alicante.

I've been passionate about technology since my early days, and I've dedicated my career to mastering software development and blockchain technologies. As the CTO at KFS, I lead the development of enterprise blockchain solutions and contribute to the Hyperledger community.

My journey in software development began with full-stack development at GeoNet, where I worked on tax applications and optimized system performance. At ALTIA, I enhanced my skills by working on complex database migrations and e-filing systems for EUIPO.

Today, I specialize in Hyperledger Fabric and distributed ledger technologies, helping organizations implement and optimize their blockchain infrastructure. I'm particularly focused on creating tools and solutions that make blockchain technology more accessible and efficient for enterprise use.

I'm also an active contributor to the blockchain community, creating educational content and developing open-source tools. My work includes the development of Kubernetes operators for Hyperledger Fabric and various tools that simplify blockchain deployment and management.
