About
I’m John DeLay, founder of Changepoint Analytics. I build AI and data science systems for healthcare and financial services organizations — the kind of work that requires both technical depth and an understanding of what happens when a model gets it wrong in a regulated environment.
I’ve built and deployed LLM-based workflows at a health tech company focused on prior authorization and clinical decision support. I’ve validated quantitative risk models at a major regional bank under SR 11-7 requirements. I’ve done Medicare quality analytics and program evaluation at a national quality improvement organization. And I’ve contributed to peer-reviewed public health research through UAB.
Who I work with
Healthcare organizations — health plans, health tech companies, provider groups, and quality improvement organizations. If your team is trying to extract signal from clinical notes, build explainable models from claims data, or stand up reporting that actually reflects what’s happening clinically — that’s the work I do.
Financial services firms — regional banks, credit unions, risk and compliance teams. If you need models that are accurate and auditable or have analysts spending too much time on data prep instead of analysis, I can help.
Academic researchers — faculty and graduate students who need a collaborator for data analysis, study design, grant support, or manuscript preparation. I’ve worked in that environment and understand what peer review and IRB compliance actually require.
Small businesses that don’t fit neatly into any of those categories are welcome to reach out. The engagement model is the same — scoped to your problem, delivered without jargon.
What engagements look like
I take on a small number of clients at a time. Projects are scoped to a specific deliverable: a working model, a deployed pipeline, a dashboard your team will actually use, or a manuscript-ready analysis. I don’t do open-ended retainers without a defined scope.
Every engagement ends with documentation and a handoff. If you need your team to maintain or extend the work after I’m done, I build for that from the start.
