Grounded in real systems
Every chapter opens on a concrete scenario before it defines anything. You learn not just how a tool works but where it belongs, and when reaching for it is the wrong call.
The Complete
Become a modern data architect for the AI and agentic era. Design and build production-grade, cloud-native data platforms, not just pipelines, that carry analytics, machine learning and the applications built on top of them.
A hands-on path across SQL, Python, orchestration, streaming, warehouses and multi-cloud architecture, building the judgment to choose the right pattern for the problem rather than the syntax for the tool.
Why this book
Every chapter opens on a concrete scenario before it defines anything. You learn not just how a tool works but where it belongs, and when reaching for it is the wrong call.
Forty-four chapters across ten parts, numbered and sequential. You always know where you are and what comes next, instead of assembling a curriculum out of disconnected tutorials.
An entire part is given to agentic workflows: coding agents, LLM-assisted pipelines, and the judgment to review what they produce. The skills that separate the next decade from the last.
Curriculum
Built from the live instructor-led course. Chapter numbers restart inside each part, so a part can grow without renumbering the rest of the book.
What you build
Every part ends in something executable: a model that builds, a DAG that schedules, a warehouse that loads. The commands below are the shape of the work.

A few of the people who have come through Cloud Data Engineering, on what the programme was actually like.
Cloud Data Engineering
I had a great learning experience. The content is up to date with current industry needs and covers multiple cloud architectures, including AWS, Azure, and Snowflake. The course also focuses on solving complex problems using cost-optimized solutions. The "Data Foundry" books helped me tremendously in building my theoretical knowledge and keeping pace with the practical content covered in the classes. Overall, I am highly grateful for the opportunity to learn and grow through this course. I am now applying the data engineering concepts and skills I learned in my professional work. Appreciations to the team behind this work!
Cloud Data Engineering
I was part of the Salani Data Engineering batch, and it was a very valuable learning experience for me. I learned SQL, ETL pipelines, and gained hands-on experience with AWS through various projects. The skills I gained have been extremely useful throughout my professional journey. They helped me during my first internship at the State Bank of Pakistan and continue to help me in my current role as a Machine Learning Engineer at Bank Alfalah, especially with SQL and ETL pipelines. I am truly thankful to Sir Qasim for giving me this opportunity and helping me build a strong foundation in Data Engineering. It has definitely been one of the most useful learning experiences for me.
Cloud Data Engineering
I had the privilege of being taught by Sir Qasim Hassan during the Cloud Data Engineering bootcamp at Saylani, and the impact of his mentorship on my career has been immense. Sir Qasim does not just teach theory; he breaks down complex architectural patterns, modern data pipelines, and cloud systems with exceptional clarity and real-world relevance. His focus on industry-grade engineering practices gave me the technical foundation and problem-solving mindset required to scale high-impact systems. The concepts and discipline he instilled are directly responsible for my growth into a Full-Stack Engineer and Team Lead at Bluehawke (Al Habib Groups). Anyone fortunate enough to learn under Sir Qasim is learning from an outstanding mentor and an exceptional engineer.
Cloud Data Engineering
I had the opportunity to study Cloud Data Engineering under Sir Qasim Hassan and it was one of the best descisions i took. The course from start to finish had everything a person needed to know in order to not just be familiar with CDE but the ways of Sir Qasim led us to have a practical implementation of it. The course itself is very fun to study and the ways of teaching was itself a huge help for anyone who knew nothing about it in he beginning but you come out a polished technical person. My personal experience was great with Saylani for when I took this course and I would higly recommend it to anyone who is thinking about joining. As of right now I'm working as an AI Engineer and the use of clouds has become much simpler because of everything i learned from this course.
Cloud Data Engineering
The course gives you not only solid technical knowledge but also practical ways to handle real problems that appear in industry. Its clear lessons and hands-on work made complex cloud data topics easy to apply. I finished feeling better prepared and more confident in my skills.
Cloud Data Engineering
The Cloud Data Engineering programme was a great learning experience, providing hands-on skills in Python, Pandas, NumPy, web scraping, Snowflake, Docker, and modern data engineering tools. Real-world projects strengthened my understanding of data pipelines and cloud solutions while preparing me for a career in Cloud Data Engineering

I really enjoyed learning Cloud Data Engineering at Saylani SMIT. The course gave me hands-on experience with Python, SQL, ETL, AWS, Kafka, and Apache Airflow. The practical sessions helped me understand how these technologies are used in real projects. Overall, it was a very useful course and helped me improve my technical skills.
Cloud Data Engineering
I have learned core data engineering concept from the course and very satisfied. Currently working as a Data Analyst for a tech company.
Cloud Data Engineering
I Learned Cloud Data Engineering from Sir Qasim Hassan at Saylani, and honestly it made a real difference for me. He breaks down stuff like data pipelines, cloud architecture, and ETL in a way that actually makes sense, none of that dry theory-only approach. He keeps things practical so you walk away knowing how it actually works in the real world. I'm currently working as a Data Analyst Engineer at Mod Ventures, and I still use a lot of what I learned in this course on a regular basis, especially around data pipelines and cloud stuff. Big thanks to Sir Qasim for the mentorship and for putting together a course that actually preps you for real work. Would definitely recommend it to anyone looking to get into Data Engineering.
Cloud Data Engineering
My name is Muhammad Waiz Imran, and I am an alumni of the 2025 Cloud Data Engineering batch at Saylani. When I first started at Saylani, I knew absolutely nothing about the field—I didn't even know the "D" of data engineering. However, through hard work and learning, I can now proudly call myself a Multi-Cloud Engineer.
Cloud Data Engineering
Overall it was a valuable, practical learning experience. The course gave me hands-on exposure to AWS tools like S3, Glue, Athena, and Redshift, and helped me build real end-to-end pipeline projects and skills that directly helped me land a data engineering internship after the course. It's great to see they've now multi-cloud approach, this makes the program even stronger and more aligned with what the industry actually expects today. One area that could improve it further is adding mock interviews focused on data engineering roles. Overall, for a free program, it delivers excellent value and I'd recommend it to anyone serious about breaking into data engineering.
