About Me

I build and evolve distributed platforms at enterprise scale. My work at Atlassian includes petabyte-scale media storage, zero-downtime migrations, and data residency for enterprise customers.

I also help engineering teams make better technical decisions through architecture guidance, mentoring, and incident review.

Beyond writing core production software, my interests extend to systems programming, running self-hosted environments, photography, and exploring local artificial intelligence applications.
