Who I Am

I’m Alex Opak, a Software Architect based in Zurich, Switzerland. Creator of OpenTalon, an AI enterprise orchestration eco system, the Talon expert system programming language, and the Expert-in-the-Loop (EITL) paradigm. With over 15 years of experience in software design and development, I specialize in building scalable, high-availability systems.

From startups to established companies, from individual contributor to CTO.

  • Distributed Systems – Elasticsearch, Kafka, event-driven architectures
  • Infrastructure – Kubernetes, Helm, Docker, Terraform, CI/CD pipelines
