Paid

Master the in-demand skill that companies are actively seeking: developing and implementing custom Large Language Models (LLMs). In this course, you will learn how to fine-tune open LLMs using corporate data and deploy your models efficiently with AWS tools like SageMaker, Lambda, and API Gateway, alongside creating intuitive interfaces with Streamlit for employees and clients.

Course Overview

This is not "just another introductory AI course." Instead, it is a practical, in-depth exploration of the skills that distinguish AI engineers on real-world projects. You'll engage in fine-tuning using QLoRA—an approach that significantly minimizes resource consumption—and transition the model into a production-ready service.

Key Learning Outcomes

What you will master:

  1. Fine-tuning open-source LLMs with your own datasets, including corporate data.
  2. Hands-on experience with QLoRA, bfloat16 training, dataset chunking, and attention masks.
  3. Utilizing the Hugging Face ecosystem, including the Estimator API, and setting up an MLOps pipeline on AWS.
  4. Model deployment and integration with tools like SageMaker endpoints, Lambda, API Gateway, and monitoring.
  5. Creation of a simple business UI using Streamlit.

Course Outcomes

From theory to code to production—experience the complete development cycle of applied AI tailored for business scenarios.

Target Audience and Career Paths

This course is designed to benefit and prepare professionals for roles such as:

  1. AI Engineer / ML Engineer: designing, fine-tuning, and producing models.
  2. AI Specialist: developing applied AI solutions.
  3. Data Scientist: preparing data, performing EDA, and building models for organizational tasks.

About the Author: Zero To Mastery

Zero To Mastery thumbnail

Zero To Mastery (ZTM) is a Toronto-based online coding academy founded by Andrei Neagoie, originally a senior developer at large Canadian tech firms before turning to teaching full-time. The academy's signature is the cohort-based bootcamp track combined with a deep self-paced course library, all aimed at career-changers and self-taught developers preparing to land software-engineering roles at top companies.

The instructor roster has grown well beyond Andrei to include other senior practitioners: Daniel Bourke (machine learning), Aleksa Tešić (DevOps), Jacinto Wong, and others. Courses cover the full software-engineering career path: web development with React and Next.js, Python, machine learning and deep learning, DevOps and cloud, system design, mobile, and the algorithm / data-structure interview prep that gates engineering jobs.

The CourseFlix listing under this source carries over 120 ZTM courses spanning that full range. Material is paid; ZTM itself runs on a monthly / annual membership model. The teaching style favours long-form, project-based courses where students build complete portfolio-quality applications rather than disconnected feature tutorials.
