What I'm looking for

I seek a senior ML/data role building production ML and generative AI systems, with collaborative teams, strong MLOps, and measurable business impact.

I am a senior data scientist and machine learning engineer with 5+ years designing, implementing, and scaling data‑driven solutions across advertising, insurance, finance, and consulting.

I build production ML systems including forecasting, propensity and fraud models, and LLM‑driven tools, leveraging Python, SQL and cloud platforms like GCP and AWS to deliver robust, monitored services.

I have led end‑to‑end projects: retrieval‑augmented LLM assistants (Llama‑3 + Vertex AI + LangChain), internal forecasting systems (statsmodels, Optuna), and automated ETL pipelines with self‑serve dashboards to empower cross‑functional teams.

I communicate technical results clearly to stakeholders, drive collaborative deployments (containerization, CI/CD), and focus on actionable insights and measurable business impact.
