👨‍💻 About Me

🚀 I'm a Full Stack & Cloud Engineer building scalable web platforms and cloud systems with React, TypeScript, Node.js, GraphQL, Kubernetes, and AWS.
🏗️ I design distributed architectures, including a multi-tenant platform that lets multiple clients run on a single core product instance.
📡 I lead real-time IoT work: integrating vibration sensors with MQTT brokers and parallelizing video streaming with a Kubernetes-based relay service.
🚚 At Oware Technologies I built the invoice and billing module and led the shipment architecture for a logistics platform.
🧩 I've built shared UI component libraries and data visualization dashboards for clients in Germany.
🎓 I'm currently pursuing a Master's in Computer Science at UCLouvain.
🌍 Based in Brussels, Belgium.
