What I'm looking for

I seek senior roles owning end-to-end data and ML platforms in high-impact, compliance-sensitive environments, with emphasis on real-time pipelines, model deployment, and observability.

I am a senior data engineer and AI/ML specialist with 10+ years of experience building production-grade data platforms across healthcare, fintech, and real estate domains. I focus on end-to-end ownership—designing pipelines, deploying models, and delivering reliable analytics for high-stakes workflows.

My work has included cutting batch jobs from 45 minutes to seconds with Spark and dbt, embedding GPT-3 and BERT models into live workflows for clinical classification and document analysis, and building real-time fraud detection systems that proactively flag risk.

Technically, I operate across hybrid cloud environments (AWS, Azure, GCP), build feature stores and observability layers, and deploy models with SageMaker, Azure ML, or containerized infrastructure. I prioritize data quality, schema resilience, and automated monitoring to keep APIs quiet and dashboards truthful.

I thrive on complex architectures and tight timelines, delivering event-driven ingestion, real-time scoring, compliance-ready governance, and scalable ML pipelines that integrate into product workflows and operational decision-making.
