Data Engineer 

Read Lorenzo's inspiring testimonial!

What was your background before enrolling on the course?

My name is Lorenzo Del Medico and my background is a bit atypical. I started off with a 3-year degree in business, which gave me a solid grounding in management and business strategy. But as time went by, I realised that what I was really passionate about was technology and data analysis.

That's what prompted me to switch to IT. I went back to school and obtained a bachelor's degree in computer science at Cnam Saint-Denis in 2021. This initial experience in programming and algorithms convinced me that I wanted to go further. So I went on to do a master's degree in Big Data and Artificial Intelligence at ESGI between 2021 and 2023.

At the same time, I had the opportunity to work on a number of corporate projects, notably as a Data Scientist on a sandwich course working on internal research projects, and also at SNCF, where I analysed the pantograph/catenary pairing. These experiences reinforced my conviction that data engineering was the path I wanted to follow.

Why did you choose the School of Data?

Data engineering is a specialism that is still poorly represented in existing training courses. Most bootcamps or schools offer courses focusing on Data Science or Analytics, but very few really emphasise data engineering, an area that is essential for companies that exploit data on a large scale.

That's why I chose the Data Engineer course at Artefact School of Data. I wanted an intensive, hands-on programme led by experts in the field.

In talking with Romain, I also learnt that I was going to be surrounded by professionals who were already experienced in IT, which reinforced my choice. Working with people who already have a good grasp of the technical side of things means you can go further in your exchanges and learn much more quickly.

What elements of the Data Analytics course have had the most impact on your learning?

There were many things I liked about the course, but what really stood out for me was the quality of the teaching staff. They are passionate professionals who have real experience in the field and enjoy passing on their knowledge. This approach makes all the difference: instead of theoretical learning that is disconnected from the real world, you get practical teaching that can be applied immediately.

I also really liked the collaborative aspect of the course. Discussions with the trainers and other participants often went beyond the simple framework of the course. We were able to discuss wider IT issues, talk about emerging technologies, share professional experiences... It was really enriching.

Another strong point is the practical projects. Rather than learning passively, we are put into real-life situations, which helps us develop professional reflexes and get up and running more quickly.

How has this training helped you in your professional development?

Before joining the course, I was looking for a job in data engineering. Despite my skills and qualifications, I couldn't get any interviews. I felt I was missing something, but I couldn't pinpoint exactly what it was.

Thanks to the training, I was able to clarify my shortcomings and structure my approach. I've gained in confidence, deepened my skills in key technologies and, above all, learnt how to position myself better in the job market.

I also realised the importance of practical application: it's not enough to know how to code and understand the concepts, you have to be able to demonstrate your expertise with concrete projects. This approach has helped me to revise my portfolio and make better use of my skills with recruiters.

Today, I feel much more ready to land the job that matches my ambitions.

If you had to describe the School of Data in one word, what would it be?

Dynamic.

This course is a real career accelerator, enabling you to acquire solid skills that can be applied directly in the workplace. The intensity of the programme, the quality of the teaching and the team spirit mean that you leave transformed and ready to take on new challenges.
