Le Wagon

My forties crisis? One thing is certain, I wanted to change my life. I worked more than 60 hours a week, sometimes even at night, without counting, for a company that was looking for its business model. Health concerns have led me to question my lifestyle and commitment. We used web agencies and developers, but the result was not up to our expectations. Creating a simple landing page for the launch of a service seemed out of reach to me. There was some mystery and fascination with the code. There are many online resources for learning. I had started a few years ago to learn the basics with Codecademy. However, learning alone in front of a screen requires will and commitment. I did not even go after the first week.

As a perfectionist, I like things to be done according to the rules. Writers learn the rules of the language, before freeing themselves from them to create masterpieces. I had to learn the basics to move forward. That's why I opted for a shortcut, to integrate a bootcamp that has proven its worth, with a well-defined methodology. The one of Le Wagon is proven. The motto is explicit : 'change your life, learn to code'. So I decided to make a leap of faith, my goal was not to become a developer, but to understand the mindset and the "working process".

I had been warned from the first day: it would be difficult, do not compare yourself to others, each progressing at his own pace. Optimistic by nature, I had not measured the extent of these warnings. Go back to the place of a student, take a class in the morning, and then continue with exercises the rest of the day, get stuck in front of an error message, try to understand why, and solve the error, move on to the next one. New concepts every day, then exercises, every day. For nine weeks. But it is worth it. Actually, thinking backward, it seems obvious: facing a complex problem, you divide it into smaller parts, and keep resolving each one. Simple to say, the execution takes time. I learned to step back on the issue, and to consider the different options. Now with this experience I can face a problem without fear, and keep confident. My first experience: debugging a website made with wordpress, the client was looking for an expert. A friend of mine sent me the request and told me to accept the challenge, and to fake it until I make it. Well I made it.

Today I am launching my web agency, targeting the Chinese market, and helping companies who want to brand overseas. In the meantime, I can bootstrap with freelance gigs with my new skills. I can discuss web marketing and web strategy with my clients, asking senior developers to help me in the process, I keep learning every day, still face error messages, but fearless and confident...

Would I recommend Le Wagon? 110%, would I do it again? Definitely. And more : I would go back to my twenties and kick my ass to learn to code.

My next challenge: be fluent in mandarin.

Who knows what my fifties crisis will lead me to..

Joining Le Wagon was one of the best decisions I’ve made. From day one, it didn’t feel like school—it felt like a community. The atmosphere was warm and collaborative, with instructors and fellow students who made learning genuinely enjoyable. It was intense, yes, but never overwhelming. The structure was solid, and the pacing kept us challenged without being burnt out.What stood out to me the most was the human aspect. Everyone—from teachers to TAs—was approachable, patient, and always ready to help. It never felt like you were “just another student.” I’ve made real friendships, gained hands-on experience, and developed not only technical skills, but also real problem-solving confidence.The curriculum is practical and industry-aligned. We worked on real projects, learned how to collaborate in teams, and left with a portfolio I’m proud of. The final weeks—building a full-stack app from scratch—were the perfect culmination of everything we had learned.If you’re looking for a bootcamp that teaches you more than just code—one that builds community, confidence, and clarity—Le Wagon is the place. I left not only with technical skills but with memories and lessons that will stay with me for life. Rating: 10/10
Would 100% recommend.

Wow, where do I even begin? I just wrapped up the nine-week Data Science bootcamp at Le Wagon, and to say it was life-changing feels like an understatement. Coming from a background with very little coding experience, I was pretty nervous, but I can honestly say it was a great decision.
The program is an intense, deep dive into the world of data, but it’s structured so perfectly that you never feel lost. We started with the fundamentals of Python and SQL and, before I knew it, we were building and deploying actual machine learning models. The curriculum is incredibly practical and project-based, which was my favourite part. You’re not just memorising theory; you're coding every single day, working on real-world challenges, and applying what you learned immediately.
What truly makes Le Wagon special, though, are the people. The teachers are absolute rockstars—many are former students who know exactly what you're going through. They don’t just give you the answers; they guide you to find the solution yourself, creating a supportive and fun learning environment. The final two weeks are spent working in a team on a final project, building a full product from scratch. This was an amazing way to experience agile development and teamwork, just like in a real tech company.
The bootcamp is definitely challenging, but it’s also incredibly rewarding. I walked away with a solid foundation in data science, a portfolio of projects I’m proud of, and a huge confidence boost. Plus, you become part of this massive global community of alumni and get lifetime access to the learning platform, which is amazing for continued growth. If you're looking to switch careers and dive into tech, I can't recommend Le Wagon enough. It’s an intense, thrilling, and transformative experience

This bootcamp is supportive of you from day 1 until the last day and even beyond that timeframe they are still helpful and supportive. All the teachers and staff you encounter throughout the bootcamp know what they are talking about, is passionate and patient with you when you struggle understanding a concept or help debug with you. They love the work that they do and by having small classes, they have enough time to help each student succeed in the course. The buddy system also helps so if the teacher is unavailable from helping someone else, at least you have another student to bounce ideas off of or help you if they learned the concept faster then you. 

Dear prospective course participant

My experience during the past 9 weeks as a student of batch #2012 in the Data Science & AI bootcamp at Le Wagon on-site in Barcelona was: 

• 💪 intense, 
• 🫀 inspiring, and
• 🚀 life-changing 

Or in Haiku-form: 

• 🌊 Into cold water
• 🦘 A Wagoneer Leaping up
• 🍀 Chance of a lifetime

🌸 From 14.04.2025 to 13.06.2025, my body and mind were firmly rooted and blossoming at Carrer de la Diputació, 409, L'Eixample, 08013 Barcelona, Spain. 

😄I particularly enjoyed the engaging and challenging learning atmosphere, which was fostered thanks to an amazing group of teachers on-site in Barcelona!  


# Before: Comprehensive Curriculum

Checking out the curriculum of our bootcamp opens up an in-depth view of all relevant hard- and soft-skills a modern-day data scientist must master:

• 💻 Setup participant laptops, install software and connect to the KITT learning platform (https://kitt.lewagon.com)
  • ⏳ Lifetime access for alumni includes course material updates, an essential feature in this rapidly evolving field
  • 🥚 Easter Egg: Like its homonymous talking car in the 1980s TV show *Knight Rider*, KITT is a playful nod to that fictional AI co‑pilot, assisting his human users through the bootcamp jungle. 
• 🐍 Python and SQL for Data Science
• 🪐 Jupyter Notebooks
• 🎲 Mathematical Foundations: Algebra, Calculus, Statistics, Probabilities
• 🤔 Decision Science, Statistical Inference, Linear and Logistic Regression, Effective Communication of Results
• 💡 Machine Learning Tools include Time Series and Natural Language Processing
• 🌱 Deep Learning Tools include Convolutional and Recurrent Neural Networks, as well as Transformers
• ⚙️ Machine Learning Operations include Cloud Training, Predict in Production, and User Interface
• 🧠 Final Project includes pitching your project idea to convince your peers to join you on an exciting journey during the last 2 weeks together!

# During: Information Overload

A note to the perfectionist voice inside of us:

• 🤐 SHUT THE F*** UP!!!
• 📝 This course contains an OVERWHELMING amount of information which my human brain was nowhere near able to digest in one 9-week-go.
• ♾️ Especially the countless rabbit holes which are sprinkled throughout the course did a great job of evaporating whatever little time I had left myself besides studying in class, studying at home, sleep, socialize, eat, and work-out (ordered by duration).
• 🌀 For me, being forced to PRIORITIZE and focus on what truly matters to ace the daily challenges and final project with my buddies was an immersive and deeply fulfilling flow-experience. 

# After: Job Seeker Program

👔 I signed up for the Comprehensive Job Seeker Program. 

• 💸 Thanks to my savings, I was not under an immediate financial pressure to find a job during the bootcamp, deferring the job seeker program to the time after the bootcamp, i.e. starting now. 
• 🤗 I'm grateful that I could embrace this opportunity to become completely absorbed in this coding-learning-bonding experience during the bootcamp while shutting the outside world out as much as possible. 
• 🪽 Now that the bootcamp is already over (those 9 weeks were FLYING) I am refactoring my first and second brain (physical and digital) to figure out where my journey will continue. 
• 📈 Although I cannot yet make any statement about the effectiveness of this Job Seeker Program for me personally, it too gives me a very complete first impression, which is consistent with the rest of the bootcamp. 
• 🎯 Wherever the professional path may lead me from here, my search has become much more targeted and CLEAR to me. 
• 🫀 Thanks Le Wagon ! 
  
  
  

I really like that the Web Development Bootcamp is designed with progressive challenges. If I couldn't manage to wrap up one of those in a session, I always knew that in the next lecture, I would have the chance to strengthen the same skills with a more advanced challenge. 
I can say that the whole program is very well designed, and you end up understanding all the bootcamp content and acquiring tons of different skills related to the programming languages that are being taught.

The teachers are super experienced and they always help you to solve your tickets (issues) without giving you the final answer, but by guiding you to implement in your code what is needed.

Regarding the staff members, they are very nice! It is very easy to reach them at any time, and they are always very enthusiastic to assist you.
I'm very happy that I decided to take the Web Development Bootcamp. I think that what I have learned in 6 months will have a very positive impact on my future professional career.
