  • Applications & Tooling: Develop end‑to‑end apps using Streamlit (frontend + backend) and build scalable workflows and Databricks Apps for data processing, experimentation, and deployment.
  • Data & MLOps: Work with Python/SQL and modern data platforms to productionize models (versioning, monitoring, retraining, CI/CD) with an emphasis on performance, reliability, and security.
  • Collaboration: Partner with product, engineering, and business teams to identify use cases, scope experiments, and translate outcomes into measurable impact.
