Early steps in the digital world
At eleven, he began exploring how websites were built with Blogspot and Wix and experimenting with HTML and HTML5. At thirteen, he created forums for gaming communities such as SA:MP and Habbo Holos. That curiosity marked the start of his journey into digital work.
Design, e-commerce and AI
He founded Contundente BE in April 2025. He also created Contundente Shop, an e-commerce business, and opened his first Shopify store in 2025. Running his own business strengthened his attention to product presentation and the customer’s journey through an online store.
He has extensive experience with artificial intelligence and keeps learning about emerging tools and market trends. His design work includes Adobe Photoshop and Adobe Dreamweaver, alongside using Antigravity in his projects.
Content and communities
He began creating content for football pages on Facebook at a young age, growing them to as many as 150,000 followers. That work taught him how to connect with an audience, develop content and build a community.
In 2019, he created Latinos BE and the Latinos Hispanohablantes en Bélgica community. The original Facebook group reached 30,000 members before it was closed; the current group has 5,000 members.
He also created “Trabajo en Bélgica | Empleo y oportunidades reales”, a WhatsApp community with more than 800 active members and an Instagram account with over 18,000 followers. Managing these communities has given him experience in online visibility, SEO and advertising, particularly in the Belgian and European markets.
Learning and perspective
His training includes a Meta marketing course and SEO focused on websites. He keeps learning so he can apply new tools thoughtfully and according to each project’s needs.
Travelling and discovering other cultures, perspectives and approaches to design has broadened how he understands businesses and creates projects. That outlook complements his commercial background and his attention to each brand’s visual identity.
