This is where theory and all the applications we learned about machine learning all come together, The last piece of the puzzle of learning machine learning – The Machine Learning Engineer Roadmap 2025 with resources.
So far in this series we covered:
What is Machine Learning – The fundamentals and the importance of machine learning field.
Machine Learning Problems – Different type of categories of machine learning problems and their applications in real world.
Machine Learning Process – Step by step guide from data collection to deploying a machine learning model.
Machine Learning Tools and Mathematics – All the core tools and math that form this transformative field of machine learning
So, now we will dive into step by step roadmap to learn machine learning with the resources mostly free. It doesn’t matter whether you are a beginner or an expert in this field, this roadmap will offer a structured plan to help you navigate the journey of machine learning.
It is not a must to follow only this roadmap as we all know machine learning is all about exploring you can explore more and find your own curiosity to learn this field. But this roadmap I will guide you what are the topics that you needed to cover in order to understand every concept of machine learning.
Foundational Knowledge
When we are going to learn about machine learning most people think the first thing you need are the theories of machine learning. It is fine to start machine learning theories but when you dive deep into the field you will surely find this boring and difficult to continue. Therefore, before dive into machine learning, what we need is foundational knowledge. When it comes to foundational Knowledge we will need the basic of programming skills, mathematics and statistics, SQL and database, Data handling and version control.
Programming skills:
The most widely used programming language in machine learning field is Python. I say it is the easiest programming language to learn but you need to master that. Then you will need to know the knowledge of object-oriented programming concepts (OOP) using python language. To learn these concepts, I recommend following two video tutorials which are free and you can learn form YouTube by following the link.
Harvard CS50’s Introduction to Programming with Python – Full University Course taught by David J. Malan
Python Object-Oriented Tutorial playlist by Corey Schafer

Mathematics and Statistics
Then you will need the knowledge of mathematics and statistics which I consider as the backbone of machine learning. Here you will learn the concepts like Linear algebra, calculus, probability, and statistics. To learn these, I will recommend following resources both free and paid ones. Following either only free resources or paid resources will be enough.
Free:
- John Krohn’s Linear algebra YouTube playlist
- John Krohn’s Calculus YouTube playlist
- Khan academy Probability and Statistics Course
Paid (with certificates):
- Mathematics for machine learning specialization imperial college (Coursera)
- Probability & Statistics by Deep learning (Coursera)
SQL and Database
It is important to know how the data is interacted using databases for handling large datasets and SQL will play a crucial role in this part. Following the three free resources will be more than enough to get an understand of how SQL and Database works.
- SQL YouTube tutorial for beginners by freeCodeCamp
- Relational database certificate by freeCodeCamp
- SQL YouTube Tutorial for Beginners (and Technical Interview Questions Solved) by freeCodeCamp
Data Analysis and Visualization
This will be crucial for data handling as data analysis and visualization needed to understand how preprocessing of data is done before feeding them to machine learning models. For this these free resources will cover all the concepts you needed to know.
- Data analysis certificate by freeCodeCamp
- Data Analysis with Python Course YouTube tutorial- NumPy, Pandas, Data Visualization by FreeCodeCamp
- Python Data Science Handbook – Jake VanderPlas
Data Structures and Algorithms
Whether you are a software engineer or a ML and AI engineer without data structures and algorithms you won’t exist. If someone wants to be an expert in the field of computer science he needs to have a very good knowledge about data structures and algorithm. To learn this, we will again go to some free resources offered by freeCodeCamp which is true gem for learners worldwide.
Version Control
Just like data structures and algorithms, version control is a must to become an expert in computer science field. Learning Git and GitHub is very important to manage the code and collaborate effectively in projects. By the following crash course which is again offered by freeCodeCamp is more than enough to get all the needed knowledge about Git.
Cloud Computing
Just like machine learning and AI, Cloud computing will be the next big thing in the world. All the experts likes to deploy their models in online cloud platform rather than in their own local machine which will be limited to only himself. Google Cloud, Amazon Web Services, Microsoft Azure are some of the big names in the cloud computing. You can learn with following resources which will be provided by none other than the relevant platform itself.

Machine Learning Knowledge
Finally, the wait is over now you are going to actually learn machine learning for real. After all the foundational knowledge in on the table it is time dive deep into the core concepts of machine learning.
The only course you needed to learn the basics of Andrew Ng’s Machine Learning Course on Coursera. It is like the bible of Machine Learning. I don’t think there are machine learning engineers who had not done this course. You can do it for free but if you want to obtain a certificate you need to pay which I’m assuring will not go in vain. After that course there is an amazing free YouTube tutorial by freeCodeCamp which is the best hand on introduction tutorial to learn machine learning. These two will be more than helpful for anyone to get started.
- Machine Learning Specialization by Andrew Ng (Coursera)
- Machine Learning with Python and Scikit-Learn YouTube tutorial– Full Course by freeCodeCamp
Deep Learning Knowledge
After learning the machine learning concepts, we dive into a little advanced subset of ML that is deep learning. Again, to learn this Andrew Ng comes to save us with an amazing course which can be learn free and if you want a certificate you should pay.
After that we need to understand how the two big dogs of deep learning platforms PyTorch and TensorFlow works. For this Daniel Bourke have made two amazing tutorials on YouTube where you can learn free and master the both platforms while slowly becoming an expert in machine learning.

Practical Experiences
Although understanding the theory behind machine learning is essential, real knowledge and skill development occur when that information is put to use through practical application. Working on real-world projects enables you to address issues that are rarely discussed in theoretical classes, like deployment, performance tweaking, and complicated data.
Kaggle, a gathering place for data science enthusiasts, is among the greatest sites for obtaining real-world experience. Kaggle gives users access to competitions, real-world datasets, and community-driven learning. You may tackle a variety of machine learning tasks, hone your coding abilities, and pick up sophisticated strategies from other competitors by competing.
As you advance, start building a personal portfolio that highlights your completed tasks. A range of tasks, including data collection, model deployment, and exploratory data analysis, should be highlighted in this portfolio. Because it shows that you can apply theoretical knowledge to real-world situations, a well-organized portfolio can greatly improve your chances of landing a job.
In addition to projects, think about starting a blog or documenting your educational path. In addition to strengthening your understanding, exchanging case studies, tutorials, and thoughts with the machine learning community fosters a sense of community. A blog can be used as a tool for personal branding, demonstrating your knowledge and enthusiasm for the subject.
Finally, work together on open-source projects or support continuing research efforts. Collaborating in groups on practical applications develops your problem-solving and cooperation abilities, preparing you for the cooperative nature of industry tasks.
