The Best Athens Coding Bootcamps Of 2025

Having already completed the Professional Diploma in Data Analytics at Big Blue Data Academy, an experience I was extremely satisfied with, I decided to continue my journey with the Data Engineering Bootcamp—and I’m glad I did. The program is intensive and covers a wide range of essential tools and technologies, from Python and SQL to Docker and Airflow, providing a strong foundation for anyone looking to transition into data engineering.

What stood out the most was the hands-on approach and the real-world orientation of the projects, which helped me consolidate my skills. At the same time, I appreciated the dedication of most instructors, many of whom are active professionals in the field. On the flip side, a few sessions felt less structured, with certain instructors assuming prior knowledge that beginners might not have—something that could be improved in future editions of the program. Also, while the bootcamp is quite demanding, especially if you are working full-time, this is something to expect from such an accelerated learning experience.

Another strong point of the program was the career support that came along with the training. Apart from the technical skills, we also had sessions dedicated to CV building, LinkedIn optimization, and interview preparation. What I personally found most useful were the individual discussions with instructors, where I received direct and practical feedback tailored to my own profile, as well as advice on how to approach the job market more strategically.

Overall, I would recommend this bootcamp to anyone who wants to build a solid entry point into data engineering, especially if they value a practical, project-driven approach combined with strong networking and career support opportunities.
