Computer science student @UMons by night looking for a new opportunity by day while launching Acteble.
All the projects I have been involved in have been developed with a strong focus on Software Craftsmanship principles (clean code, clean architecture, and DDD) as best practices to ensure highest standards of quality, maintainability and scalability.
Building Acteble, a geo-located social platform that pairs travelers around shared activities under spatio-temporal and multi-criteria constraints. Sole founder, architect, and developer. The R&D layer doubles as the dissertation for my MSc in Computer Science at UMons.

Software modernization within the .NET stack following domain-driven design and clean code principles. Implementation of Azure AI services in a .NET solution.
This qualifying training aimed to strengthen the technical skills acquired during my bachelor's degree program at EPHEC. In addition, during the extension, we received an introduction to Business Intelligence and ETL processes (Data Warehousing) using Microsoft tools (SSIS, ...). This comprehensive training covered various areas including SQL Server, Node.js, Express.js, React, and Angular, encompassing everything from database development to user interface and backend.

Working alongside Baptiste Grosjean on the EMVI project has been an incredibly rewarding experience—both professionally and personally. Not only is Baptiste a highly skilled developer with a sharp eye for design and functionality, but he’s also been a mentor and an inspiration throughout our collaboration.
I’ve learned so much from him—from best practices in Flutter development to the importance of thoughtful UI/UX and clean architecture. He’s always willing to share his knowledge, explain complex ideas with clarity, and support the team in any way he can.
What stands out the most is Baptiste’s ability to turn challenges into opportunities. His calm, focused approach and problem-solving mindset helped us overcome technical hurdles and build features that truly improve user experience. On top of that, his collaborative nature made working as a team feel seamless and motivating.
If you're looking for someone who not only delivers exceptional results but also uplifts everyone around him, I can't recommend Baptiste enough. He’s a fantastic developer, a great teammate, and someone I’ve been lucky to learn from.

I had the pleasure of working with Baptiste for a year, with the added joy of mentoring him on a project for three months. If there's one thing that stands out about Baptiste, it's his boundless energy. Whether it's 9 AM or 9 PM, he's always the most enthusiastic person in the room—sometimes even more enthusiastic than the coffee machine.
Baptiste brings a contagious energy to any project he's part of. He’s outgoing, smart, and has an eagerness to learn that is truly admirable. Whether he's diving into a complex task or asking insightful questions, he's always in search of knowledge. His enthusiasm for learning, especially when it comes to leveraging tools like ChatGPT, is both impressive and a little intimidating. Seriously, if ChatGPT had a best friend, it would be Baptiste!
He’s also incredibly hands-on, never shying away from rolling up his sleeves and getting deep into the work. His approach isn't just theoretical; he's all about practical, tangible results.
In summary, if you're looking for someone who brings enthusiasm, intelligence, and a touch of humor to every task, Baptiste is your person. Working with him was not just productive, but genuinely enjoyable.

Hoewel we niet direct samenwerkten, had ik altijd een heel fijne connectie met Baptiste. In een mengelmoes van Engels, Nederlands en Frans deelden we vaak leuke gesprekken. Zijn enthousiasme en energie zijn echt aanstekelijk, en hij weet een prettige, informele sfeer te creëren in elke interactie. Baptiste is iemand die een positieve dynamiek met zich meebrengt.
