I'm a full-stack developer specializing in React and Node.js, with PostgreSQL databases and scalable backend architectures. I enjoy building modular backends, real-time features, and production-minded designs that scale. I'm driven by startup-level energy, value secure, maintainable code, and clear documentation. I thrive in collaborative environments and am open to relocation for the right opportunity to contribute and grow.…I'm a full-stack developer specializing in React and Node.js, with PostgreSQL databases and scalable backend architectures.
