I'm an Atlassian certified Jira server and cloud manager with 2 years of experience in the field. I'm able to help you to set up your Jira instance, assist you with the project design and customize it for it to suit your needs (It does not matter if it's Jira Software, project management or service management). Furthermore, I have extensive knowledge about the Jira internal API and best practices, so I can give you advice if one of your requirements is better accomplished using a plugin from the Atlassian marketplace.
Lastly, i also have experience in other Atlassian tools, like Bitbucket and confluence.
