Who you'd be working with

Xavier Ransome

Tech Leap LLC is my consulting practice. Ten-plus years building data platforms in environments where being wrong is expensive: veterans' health records, defense security cooperation, investigative and geospatial intelligence, aerospace quality, nuclear operations, and payer claims.

I work hands-on. You get the person who writes the PySpark and reads the execution plan, not an account manager with a delivery team behind a curtain. That's also the constraint. I take a small number of engagements at once, and I'll tell you early if yours isn't a fit.

Most of what I'm hired for now sits at the seam between data engineering and AI. Teams arrive with a model or an LLM initiative that has stalled, and the model is almost never what stalled it. The data feeding it is.

Tell me what's broken.

A short description of the platform and what isn't behaving is enough to start. I'll tell you within a day whether it's something I can help with.
