What I'm looking for

I seek a leadership role where I can ship ML-driven products, scale data platforms, mentor teams, and deliver measurable revenue and efficiency gains in a collaborative, growth-focused culture.

I am a data leader and senior data scientist focused on turning messy data into actionable products that drive measurable business outcomes. I combine statistical rigor, ML modeling, and product-minded analytics to inform strategy and optimize spend.

At HelloFresh I built retrieval-augmented-generation (RAG) chatbots, causal evaluation frameworks, and a pricing/time-series stack that leadership cites as a major 2024 accomplishment—helping save over $5 million and increasing customer order rate by 8%.

My consulting background spans solution architecture and production ML across healthcare, telecom, and government clients, plus hands-on experience building vision, NLP, and forecasting systems with GCP AutoML, YOLO, SageMaker, and Databricks. I have led small teams and shipped scalable pipelines and dashboards to drive adoption.

I pursue interpretable ML, reproducible pipelines, and pragmatic experimentation—leveraging LLMs/RAG, causal inference, and robust MLOps. I am motivated to lead teams that launch new products, optimize revenue, and institutionalize data-driven decision making.
