Alumni Story: Thomas enriches his AI career with data science skills
PROMO 2026
Thomas Hebert
Read the inspiring testimonial from Jaimes, an alumnus of the Data Science & AI training !
What was your background before joining the Data Science & AI course?
My name is Thomas, I'm 26 and I'm a graduate of the Android Master's programme at Sorbonne University. It's a Master's degree that deals with AI applied to robotics, virtual environments, multi-agent systems and decision support. Before taking this course, I was an innovation financing consultant for companies. The difference is that my Masters is more focused on innovation and research. At the time, when I had to choose my Master's degree, I had the choice between that and a Master's degree that was more data-oriented. I chose the core option, bearing in mind that when I did my research, which was four years ago now, the market was different from today. There were more prospects, more jobs, quite a few companies booming. And then there were quite a few differences compared to today. They recruited a lot of juniors, so there's less room for them on the market today. And then AI came along, which changed quite a lot the way we react to offers, and how we rethink different jobs. And today, it's a lot more mixed jobs between research, data and senior positions that are more in demand. So I need to be able to increase my range of skills to adapt to today's market.
What didn't your Master's degree give you that you were looking for in this course?
My Master's was very theoretical, very much into the different formulas, learning the different concepts, sometimes perhaps a little behind the times compared to what we were seeing in the field and very research-oriented, perhaps even a little too much so. In other words, if you didn't do a thesis at the end of the Master's, it was still a bit difficult to find a job, bearing in mind that I graduated in 2024, so it was a bit difficult. The data part, on the other hand, is something that is more business-oriented nowadays, that has a greater real-world focus, and that is still very much in demand. And that's not something I saw at all in my Masters, so I really needed to do that.
Why did you choose Artefact School of Data?
So at first I didn't know anything about it. When I was in post last year, I got my first email in June from France Travail promoting the school. It intrigued me at the time, except that I was in post, I was in the middle of my trial period, so I couldn't really do that. I thought maybe later, one day, if I ever needed it. And then in September, I had left my job by then and France Travail sent me the same email with new dates for the webinar. So I took that as a sign. And then I thought, given that at the moment I've got nothing to do and I know that it's going to be difficult to find work, knowing that I was looking for a much more technical job, one that was much closer to what I did in my Masters rather than what I did in my old job. I thought that this might be a good time to increase my skills and be much more competitive on the market.
How would you describe your experience at the School of Data?
I found it very interesting, bearing in mind that I'm not at all used to the Bootcamp format. It's something I didn't know anything about. I've always taken a very traditional route in terms of my studies. I didn't even do a sandwich course or anything. It's always been a straight line, you could say. So it's true that this aspect was very new for me. And I found it very interesting because you're much more in touch with reality, much more involved in rapid learning, whereas on traditional courses you do a lot of theory, always studying all the formulae and mathematics behind it, over long weeks, even months. In this case, we really needed to be able to get to grips with the concepts, even for people who had no grounding in the field, quickly in two and a half months. So I found it very intensive, but still very interesting and now much closer to the reality of the business, because we're basing ourselves on technologies that are fairly recent and on areas that are very much in demand today in the various offers.
What skills or tools did you learn during the course?
In terms of my skills above all, and quite a few skills that I didn't have at all, firstly data analysis. I'd done a bit of it in my undergraduate degree, but it was still relatively limited. Here, we really saw the importance of data analysis, how to go about it, what the different points to take into account are, the different dangers, what could affect the learning of models, etc. I also honed my SQL skills a bit. Likewise, I'd seen it at undergraduate level, but it's something I hadn't done for a while and I felt a bit weak in it. So this enabled me to work on it again. We've also been able to gain more skills in machine learning, because with my Master's degree, I had some, obviously, we do some. But it's not the same kind of machine learning that we do. We're more into what we call reinforcement-based machine learning, where little autonomous agents learn from their mistakes by themselves to try and get a reward. Here, we're really looking to do something guided, supervised, or even something a little deeper in deep learning to process pure data and make either predictions or classifications to get a final result that's important for the business. So that's quite a change. It means that between my course and the bootcamp, I'll be able to see the whole of machine learning with everything I've learned. The same goes for deep learning, something I've only seen half of, so to speak. Then there's a part that I hadn't done at all, the engineering part, which is very much in demand these days, from what I've seen on the Internet, the whole part where we want to build pipelines, where everything is automated, we can deploy in the cloud, etc. Then we can make the various applications available to the public. Then we can make the different applications or models available to companies so that they can make their predictions automatically without having to go back into the code and run programs manually. That's something I hadn't seen at all, because once again, my training was very theoretical, so there was no business reality behind it. So that really helped me to realise just how important that part is.
Can you tell us about a project you did during the bootcamp?
Right now, we're working on a project that will mark the end of our training. There are four of us, and we're going to present it by the end of next week. We're working on a major project involving the prediction of different plant species. We've chosen to concentrate on herbs, so thyme, basil, mint and so on. And the aim is to train models to use an image to predict as effectively as possible what species of plant is in the image. So it's a fairly substantial project, because we have to do everything from A to Z, from data analysis to final deployment, so that we have an application that works for the demonstration. And it's also a project that we'll use for our final certification, which is due in about a month's time, to really certify that we've really acquired the skills during the bootcamp.
How would you describe the teaching at Artefact School of Data?
I find it interesting compared to a traditional course where there are a lot of people. I used to have classes of between 25 and 35 people, sometimes depending on the semester. So it's true that having much smaller batches, there were 12 of us. Of course, we were also with the data analyst and data engineer groups, but in terms of the data scientist part, there were really only 12 of us. And it's true that that's practical, because it makes it easier to forge links with the others, which is relatively practical for the projects afterwards, to be able to communicate more easily, and to work in small groups on the exercises. And it's true that because we're in a small group, communication with the trainers is easier. And you get on better with them, you feel much closer. Sometimes, we can also go on little outings in the evening to strengthen the bonds a little more. So it's true that you get a real sense of support, which you don't necessarily get in traditional training courses where teachers are sometimes more distant from their students. Here, we have a real feeling of support and we don't necessarily feel in difficulty, because if we have the slightest problem, we know they're there to help us. If you have any questions, they spend a lot of time helping you with the various exercises. So I find it very user-friendly and very practical for learning.
What would you say to someone with a grounding in data/IA who is thinking of taking this course?
If you want to know a little bit about the content of some masters degrees in data engineering, it can be interesting because the whole data engineering part is not necessarily seen, but it's something that's very sought after and very important today. And that, I think, is something that is lacking in universities in particular. In engineering schools, perhaps a little less so, I'm not familiar with all the courses either, but I think they are perhaps a little more able to offer this. But in universities, it's much more specialised. So they concentrate mainly on the really pure training part, the mathematics and all the theory behind it. But it's not exactly the same thing when it comes to the reality of the job. And that's also why it's so hard for juniors to find work in this sector these days. So it's true that it's very interesting for this part, with this bit of apprenticeship that's been added for a fortnight at the end of the course. And for people with a background like mine, especially in research and development, yes, it's totally important. It's, let's say, in tune with the times in terms of what's required in terms of skills. Because, unfortunately, in France, R&D in this sector is not what we see most, in other countries more, but in France unfortunately less. So it's true that it allows us to acquire other skills that may be lacking in this sector. In any case, I know that I really needed to do this. So anyone in my situation would be well advised to take this course.
