  • Deep expertise in Python for backend services and AI integration.
  • Hands-on experience with Azure AI Foundry to build, deploy, and manage AI models and agents.
  • Proven experience building complex API integrations for data ingestion, extraction, and classification.
  • Strong understanding of security engineering, including PII redaction, anonymization pipelines, and secure data handling in AI workflows.
  • Experience delivering well-tested, scalable, secure, and performant enterprise systems.
  • Strong track record of working within Agile software development frameworks.
  • Proficiency with AI-assisted development tools such as Claude Code, Cursor, and GitHub Copilot.
  • Familiarity with Python libraries such as PyTorch, TensorFlow, and Scikit-Learn.
  • Exposure to visualization tools such as Matplotlib, Seaborn, or Plotly.
  • Experience building cloud-native applications, including infrastructure-as-code and observability practices.
  • Experience with at least one cloud platform and CI/CD for ML, such as GitHub Actions or MLflow.
  • Familiarity with emerging AI regulations such as the EU AI Act and NIST AI RMF.
