About Me

Data Scientist with 4+ years of experience in machine learning, deep learning, causal inference & experimentation, stakeholder consulting, and solution delivery. I specialize in predictive modeling, statistically grounded data enrichment, and analytics-driven strategies that drive measurable business outcomes. My approach is rooted in first-principles thinking - I deconstruct problems to their core and rebuild them into scalable, decision-enabling systems.
