TIL that Hubspot uses Email as a unique identifier and that kicked off a whole new surprise data clean up project.

Moving (or even more so, syncing) massive amounts of data is never as simple as people seem to assume. I was probably that naive once, I really don't recall. I know what I'm in for in a system migration, and this is par for the course.

Jessie has spent 20+ years architecting and delivering software for organizations where complexity is the norm: financial services, insurance, nonprofits, and regulated industries where getting it wrong isn’t an option. She specializes in the hard problems: unique operational workflows, cross-system integrations, and compliance requirements (HIPAA, CCPA, SOC 2) built into the design from the first conversation.

Her AI work comes out of that background. She has shipped AI to production, not just piloted it: a multi-agent research pipeline that cut a client’s investigation time from over an hour to minutes, and natural-language analytics that let executives ask plain-English questions of their operational data and get validated charts back. Years building business critical systems taught her where AI belongs in a business process and where it doesn’t.

At Codality, she leads engagements from discovery through delivery, because she’s seen what happens when that thread gets cut.
