The hardest part of an AI/ML project isn't the model.

It's asking the right questions.
I bridge the gap between rigorous science and applied machine learning. I help organizations move from messy, unstructured text to production-grade systems by asking the right questions, carefully framing the business problem, and building domain-tailored, cutting-edge solutions.

Most ML projects don't fail because of the model. They fail because the problem was framed wrong, the labels were poorly defined, or the evaluation metric didn't reflect what actually mattered in production.

Fixing those problems requires a different kind of expertise — not more advanced architecture or more compute, but better methodology. Asking the right questions. Carefully framing the problem. Thoughtfully operationalizing key concepts. Selecting appropriate methods, not trendy ones. That work happens before a single model is trained.

I have extensive experience conducting quantitative research at leading universities, working with some of the most complex text there is: dense legal documents, multilingual court judgments, and technical regulatory documents, where a misclassification isn't just a metric — it's a wrong answer about what the law says. That environment trains a specific skill set: defining valid labels, anticipating measurement error, and determining whether a model has actually learned the concept you care about.

I bring research-level rigor to every AI/ML project — from our first conversation about how to frame the problem to the final handoff to your team.
