Senior Full-Stack Developer for Marketplace

We need a senior full-stack developer to help turn an existing QIUBO marketplace prototype into a production-ready application. The work includes improving the current prototype, building new features, and ensuring the platform is stable, scalable, and ready for launch. You should be comfortable working independently, managing tasks, and delivering high-quality code. Experience with marketplace platforms and full-stack development is important. This is a long-term project with potential for ongoing collaboration.
