Vitor Schroeder Dos Anjos
@vitorschroederdosanj
Data & statistical intelligence professional building default risk models with SQL, R, and Python.
What I'm looking for
I’m a statistical intelligence professional focused on turning data into defensible models for real credit decisions. At StepWise, I created, presented, and pitched default risk assessment models to industry credit providers, while building and cleaning data banks with millions of entries using SQL, R, Python, and proprietary systems.
My technical approach is rooted in rigorous math and statistics: I’ve worked on defining parameters for aggregating data in n dimensions with HDBSCAN, developing a metric analog for measuring distance between n-dimensional objects in a statistically significant way, and exploring extensions of Markov chains via matrix composition. I also contribute to AI by fine-tuning mathematical, statistical, and physics responses through questions, answers, corrections, and annotations.
