  • Data Engineering: Understanding of data modeling (ORMs, NoSQL, SQL, JSON, XML) and data validation using tools like Pydantic.
  • AI/LLM Frameworks: Familiarity with tools such as LangChain, LlamaIndex, CrewAI, Semantic Kernel, Autogen, and Agno, plus an understanding of how large language models (LLMs) work.

Data Science & MLOps

  • Libraries: Proficiency in NumPy, Pandas, Matplotlib, Seaborn, and Scikit-learn.
  • MLOps: Experience building CI/CD pipelines (e.g., using Bicep or similar), with skills in deploying, monitoring, and maintaining machine learning models in production.
  • Prototyping: Skilled in using Jupyter Notebooks for data exploration and proof-of-concept development.
