About me

As a technology leader, I bring innovation and continuously strive to improve both the output and the developer experience and effectiveness of the teams I lead.

I spent 15 years in various technical positions at CYRRUS a.s., where projects and infrastructure I designed and built enabled the complete digitalization of client onboarding and expansion into foreign markets. I introduced the effective use of AI tools and continue to educate myself in this field, successfully bridging professional knowledge across different IT domains.

On top of that, I have delivered more than 200 different web projects as a freelancer, ranging from simple websites to complex systems. I have also designed and implemented several company infrastructures for both regulated and non-regulated entities.

Work experience

Tech Lead & Senior Developer 2021 – Present
CYRRUS, a.s. | Brno
  • Growing demands led to separating development from IT and creating a dedicated team that I led. Over the years I assembled and mentored several teams that gradually evolved.
  • In recent years I have been shifting more towards architecture and management, while still remaining active as a developer, mentor and advocate for new technologies and practices.
  • I promote a pragmatic and goal-oriented approach to both technology and people, and I aim to be a democratic leader — yet I have no problem following expert guidance when needed.
  • I am happy to discuss specific projects, architectures and technologies I work with in person.
Developer / Senior Developer 2018 – 2021
CYRRUS, a.s. | Brno
  • Software development became the priority, so I stopped working on system administration. As a full-time developer I started introducing the necessary processes and gradually gained several direct reports.
  • From scratch, I designed and built an ecosystem of projects that replaced paper-based client contracting processes and turned them into a fully digital experience.
  • Step by step we adopted modern development practices, changed the stack several times and learned from many dead ends.
IT Specialist / Developer 2011 – 2018
CYRRUS, a.s. | Brno
  • I started in the IT department as an IT specialist. Later, on my own initiative, I began delivering smaller internal projects that supported sales acquisition and management reporting.
  • I introduced the concept of webinars instead of investment seminars held in hotels, built an intranet portal on SharePoint and delivered websites for campaigns and subsidiary companies.
  • I took care of all levels of infrastructure and support, but over time the developer role gradually prevailed and became increasingly important to the company.
Various IT positions 2007 – 2011
Various companies | Brno
  • My experience before joining CYRRUS is no longer particularly relevant. I tried out several IT roles — from ICT helpdesk for a certification authority and work in a hardware service center, to IT outsourcing covering system administration for 20 companies at once.
