AI Engineering: Customizing LLMs for Business (Fine-Tuning LLMs with QLoRA & AWS)

Source: https://zerotomastery.io/courses/fine-tuning-llms-for-business/

Master an in-demand skill that companies are looking for: developing and implementing custom LLMs. In this course, you will learn how to fine-tune open large language models on closed/corporate data and deploy your models using AWS (SageMaker, Lambda, API Gateway) and Streamlit to provide a convenient interface for employees and clients.

This is not “just another introductory AI course.” It is a practical deep dive into the skills that set AI engineers apart on real projects. You will perform fine-tuning using QLoRA, a method that drastically reduces resource consumption, and then turn the model into a production service.

What you will master:

  • Fine-tuning open-source LLM on your own datasets (including corporate ones).
  • Practice with QLoRA, bfloat16 training, chunking datasets, attention masks.
  • The Hugging Face ecosystem (including Estimator API) and MLOps pipeline on AWS.
  • Model deployment and integration: SageMaker endpoints, Lambda, API Gateway, monitoring.
  • Creating a simple business UI on Streamlit.

Outcome: from theory to code and production – the complete development cycle of applied AI for business cases.

Who it benefits and what roles it prepares for:

  • AI Engineer / ML Engineer – designing, fine-tuning, and producing models.
  • AI Specialist – creating applied solutions based on AI.
  • Data Scientist – data preparation, EDA, and building models for company tasks.
  • AI Research Scientist – in-depth work with attention mechanisms and LLM.
  • Cloud Engineer – architecture and best deployment practices in AWS.
  • DevOps Engineer – automation, release, and monitoring of ML services (CloudWatch, etc.).
  • Software Engineer – integrating models into applications with scalability in mind.
  • Data Engineer – data pipelines, storage (S3), preprocessing.
  • Technical Product Manager – planning and releasing ML products, metrics, and monitoring.
