About Jan

I help companies design, optimize and scale their Jira and Jira Service Management environments.

My focus is not only on configuration, but on improving processes, automation and overall efficiency of teams.

I have experience with:
- Jira Cloud configuration (projects, workflows, permissions)
- Jira Service Management (helpdesk setup, SLA, request types, portals)
- Automation (Jira Automation, integrations)
- Cleaning and optimizing existing instances
- Supporting teams in adopting best practices

Typical results I deliver:
- Faster ticket resolution and better SLA performance
- Reduced manual work through automation
- Clear and scalable workflows
- Improved user experience for teams and customers

I am comfortable working with startups and growing companies that need a flexible and scalable Jira setup.

Let’s discuss how I can help improve your Jira environment.
