• Strong experience with NLP models: Transformers, BERT, NER
• Hands-on model training using PyTorch / TensorFlow
• Fine-tuning, PEFT / LoRA, transfer learning
• Dataset creation, labeling strategies, weak / supervised learning
• Model evaluation (precision, recall, F1) and error analysis
• Experience using LLM APIs (GPT, Claude) and hybrid ML + LLM pipelines
• Model deployment, inference optimization, and monitoring
• Ability to take ownership from research → production

Tools (Expected)

• Python
• PyTorch or TensorFlow
• Hugging Face (Transformers)
• scikit-learn
• LLM APIs (GPT, Claude)
• ML experiment tracking (MLflow / W&B)

Working knowledge

• SQL / Parquet / S3
• Embeddings & RAG (conceptual use)
• Entity–relationship modeling
