About

I'm a Senior Data Analyst with 10+ years of experience turning complex, large-scale datasets into actionable business decisions — most recently leading and mentoring a team of 4-6 junior analysts while building end-to-end data and AI workflows for a global automotive leader. At Stellantis, I work across the full data lifecycle: analyzing telemetry from 1M+ connected vehicles in a modern Data Lakehouse (Databricks, PySpark, AWS S3/Athena/Glue), architecting a Data Quality Framework that automatically detects data quality issues and consolidates them into a single Databricks dashboard, and shipping a Generative AI system — a RAG pipeline on AWS Bedrock (Claude 3 Haiku) — that cut ticket resolution time from 24 hours to within minutes for repeated support issues. I also serve as the primary bridge between Data Engineering, Product, and business stakeholders, and represent my team in PI Planning to align delivery with program-level roadmaps. Earlier, at Accenture/AIG, I built ETL pipelines, ran distributed processing on AWS EMR, and developed machine learning models for predictive risk analysis in the insurance/underwriting space. Core toolkit: Databricks · PySpark · Python · SQL · AWS (S3, Athena, Glue, EMR, Bedrock) · Power BI · DAX · LLMs & RAG Pipelines · Scikit-Learn · CI/CD (GitLab) · Agile/SAFe (PI Planning) · Jira · Confluence · Aha! · Zendesk Open to Senior Data Analyst / Technical Lead – Data Analytics opportunities where I can bridge data engineering, analytics, and applied AI to drive real business outcomes, while continuing to grow into broader technical leadership. Let's connect.
