Hi, I’m Mateusz Goszczycki, a Full Stack Developer with 2+ years of commercial experience delivering production-ready web applications. I specialize in real-time systems, marketplaces, and scalable backend architecture (NestJS + PostgreSQL), and I’ve built and deployed 3 live applications with payments, WebSockets, and AI integrations. I enjoy turning complex requirements into clean, maintainable solutions and delivering features end-to-end with reliability and speed. Before moving into software development, I spent six years as a Head Chef and Culinary Instructor, which taught me to thrive under pressure, own outcomes from start to finish, and lead teams with discipline. Those experiences give me strong resilience, fast iteration, and a customer-first mindset that I bring to every project. I’m open to remote work and relocation and excited to continue growing as a developer.…Hi, I’m Mateusz Goszczycki, a Full Stack Developer with 2+ years of commercial experience delivering production-ready web applications.
