Profile
Experte
I spent 11 years at Atlassian building and running Jira at scale - from writing Java code to managing engineering teams across Server, Data Center and Cloud. 
I know this platform from the inside out, not just from configuring it.

Since going independent, I've been doing the work I'm best at: solving the hard technical problems that slow enterprises down.

That's meant diagnosing a Jira instance processing millions of issues where core workflows were taking 30 seconds - and getting them to 400ms. It's meant leading a full Server to Cloud migration for a large enterprise with a stack of app blockers nobody had a clean answer for. 

I'm direct, I am for pragmatic solutions, provide proof and concepts: I don't disappear after the kickoff call. 

I work T&M, remote-first, and I'm usually brought in when a team has been stuck on something for too long.

If you have a Jira or Confluence problem that's been open too long - migrations, performance, custom tooling - I'm happy to talk.
