Building scalable software & modern web platforms
I'm a Software Engineer focused on building scalable end-to-end systems using Java (Spring Boot) and Next.js. I specialize in designing robust architectures, integrating modern APIs, and delivering high-performance applications for production environments.
My experience ranges from fullstack SaaS platforms and headless e-commerce systems to secure backend services and AI-powered tools. I have worked with European companies developing complex applications, deploying them on Linux infrastructure, and optimizing them for performance, SEO, and scalability.
I enjoy solving complex engineering problems, integrating AI into real products, and building software that balances strong backend architecture with modern, high-quality frontend experiences.
