Wendell Lozano

I am a Senior Data/ML Engineer with 7+ years building production-grade data pipelines and machine learning systems across finance, manufacturing, and telecommunications. I specialize in ETL/ELT infrastructure, feature engineering, and classical ML algorithms that deliver measurable business impact.

I've architected multi-cloud data pipeline infrastructure processing over 1M daily prediction requests with sub-100ms tail latency, automated ETL workflows with Apache Airflow and Terraform, and established data quality frameworks preventing the vast majority of schema violations before production.

My work has produced tangible savings and performance gains, including $12.9M+ in cost savings through predictive analytics, major reductions in query and deployment time, and improvements in model accuracy and retrieval relevance across large-scale systems.

I mentor junior engineers, standardize MLOps and CI/CD practices, and focus on scalable, observable systems—balancing rapid iteration with robust production reliability to accelerate business outcomes.
