Skills

I am a technologist, DevOps engineer, fullstack developer, product builder and entrepreneur. Turning ideas and visions into well-crafted technical solutions is my passion. As former Chief Technology Officer and co-founder of VC-backed cloud startup and market leader Talentry, I have over ten years of experience in software engineering, DevOps, cloud technology, leadership and entrepreneurship. In my role as CTO, I was responsible for building a global SaaS platform that is resilient, scalable, maintainable - and loved by our customers. Being a maker at heart, I have always remained in a hands-on engineering role while building a high-performance engineering organization.

Today, I act as an independent DevOps and software engineering consultant on a freelance basis. I enjoy both working as a hands-on engineer as well as taking over interim leadership roles. Although generally tech-agnostic, the stack I enjoy working with most is AWS, Terraform, Python, Typescript and React.
