Data Scientist | Machine Learning, Analytics & Decision Systems

プロフィール概要

I’m a Data Scientist with 6 years of experience building machine learning and data-driven solutions, with a particular background in fraud detection, behavioral analytics, customer segmentation, and risk modeling. My work has covered the full lifecycle from exploring complex datasets and identifying useful signals, through feature engineering and model development, to translating results into practical product and business decisions. I’ve worked with supervised, unsupervised, and semi-supervised machine learning, interpretable modeling, and large-scale data pipelines using Python, SQL, Databricks, and AWS. More recently, I’ve also worked on applied AI and LLM systems, including RAG pipelines for complex documents and structured data, multi-provider LLM infrastructure, and retrieval and citation systems. This included taking these systems beyond prototypes, with attention to reliability, observability, and data security. I also have several years of experience leading Data Science teams and projects and working directly with enterprise clients. My work has involved understanding customer problems and requirements, collaborating with Product, Engineering, and customer-facing teams, communicating technical trade-offs to non-technical stakeholders, and translating ambiguous business problems into well-defined analytical work and production solutions. I’m interested in projects across machine learning, applied AI, behavioral and customer analytics, segmentation, fraud and anomaly detection, predictive modeling, and data-driven decision making. I’m also open to adjacent Data Science problems where my technical and analytical background can be applied to new domains.
