• Strong Python skills for writing clean, testable, and production-grade code, with experience in prototyping and backend frameworks (e.g., FastAPI).
• Solid understanding of large language models, transformer architectures, and practical use of frameworks like LangChain, LangGraph, or similar.
• Ability to design and assess modular, multi-step agent workflows with clear metrics, including agent routing, memory, and tool orchestration.
• Skilled in prompt design, function calling, tool integration, and familiarity with RAG pipelines and vector stores (e.g., FAISS).
• Experience with fine-tuning (LoRA, QLoRA, Hugging Face), and data preparation, training, evaluation, and deployment of custom models.
• Proficiency in iterative improvement based on user feedback and testing, along with basic Docker, CI/CD, and code quality practices.
