A semantic hash lets a re-run skip writes that change nothing — and can erase the identity you meant to compare. The pattern, and the tests that catch it.

Atlassian consultant and Forge developer at LeanZero. We do Data Center to Cloud migrations and build Forge apps, and I write up what I learn at leanzero.net.

I started LeanZero because I saw an industry full of process-heavy companies charging enterprise prices for work that could be done faster, leaner, more honestly. The Atlassian ecosystem shouldn't need a small army and a six-figure budget to get things done right. I hold Atlassian Certified Administration Expert status: ACP-120, ACP-220, ACP-420 and ACP-520, covering Jira, Confluence, Jira Service Management and cloud org admin. Other certs: PSM I, SSM, AWS Cloud Practitioner. I specialize in Forge app development and run an AI-powered agentic workflow I built myself, so I can build across stacks without a dozen specialists. Cloud migrations are my bread and butter, from small teams to orgs with tens of thousands of users. The MCP Doc Processor came from a simple frustration: nothing on the market fit, so I built it. I'm not selling magic pixie dust. I'll tell you honestly what's possible, what's hard, and what you actually need. If you don't need to pay me, I'll tell you that too.
