Marco Walz

IT Consultant Blockchain

  Stuttgart, Germany

Not a random software developer. Always putting myself in the perspective of the users. Love doing Scrum and push me and my team to new limits. Passionate about new technologies and inventions that will make our all lives better and more comfortable, in particular:

  • Blockchains and Decentralized Networks
  • Self-Sovereign Identity (SSI) & Decentralized Identifiers (DIDs)
  • Internet of Things (IoT)
  • Autonomous driving 

I think that every company should empower their employees to generate new ideas and focus on core business by getting rid of wasted & repetitive work. Everything that can be automated, should be automated!
