About
I am a Senior Software Engineer on the Search AI Team at Atlassian, where I handle indexing, retrieval systems, and OpenSearch infrastructure across products. I build scalable distributed backend systems for search and information architecture workflows, and I reduced search latency by 80% with an index-per-tenant architecture. Previously I was Founder and CTO at Probz AI and at Credwise, and a Member of Technical Staff-3 at Nutanix working on the IAM authorization stack.
