About

I don't just write clean code; I build the digital engines that power complex supply chains. As a Full Stack Developer with a background in Logistics & International Trade, I possess a unique ability: I speak both "Developer" and "Operations. " I specialize in translating complex operational bottlenecks into scalable ERP, WMS, and Supply Chain solutions. My focus is on bridging the gap between manual field operations and modern technology, ensuring that software solves real-world business problems. WHAT I BRING TO THE TABLE: ️ Full Stack & Architecture: Expert in building scalable backend services (Node.js, Nest.js) and intuitive frontends (React, Next.js, React Native) using Microservices and Event-Driven architectures. Domain Expertise: Deep understanding of Logistics, Inventory Control, and Order Management workflows. I don't need "translation" to understand warehouse logic. 📈 Measurable Impact: Proven track record of digitizing end-to-end workflows, reducing manual operational errors by ~30%, and improving delivery efficiency by ~40%. CORE TECH STACK: 💻 Backend: Node.js, Nest.js, TypeScript, RESTful APIs, RabbitMQ 📱 Frontend & Mobile: React, Next.js, React Native, Redux ️ Data & Infra: MongoDB, PostgreSQL, Docker, CI/CD 🌍 OPEN TO RELOCATION: I am actively exploring opportunities across Europe and the UAE and am fully prepared for international relocation processes. (Eligible for the Highly Skilled Migrant / Kennismigrant visa in the Netherlands.). Let's connect to discuss how I can add value to your engineering team! 📧 [email protected]
