Hi, I’m Marius Catalin Bobitiu, a full-stack developer with experience building customer-facing platforms, internal tools, APIs, and cloud-backed applications across commercial and personal projects. I focus on performance, usability, maintainable system design, and end-to-end product delivery. I work primarily with React, Next.js, TypeScript, Go, PostgreSQL, and MongoDB, with hands-on experience across frontend, backend, infrastructure, and system integration. I design and deploy scalable cloud architectures on AWS (ECS, load balancing, auto scaling, VPCs, MongoDB Atlas), own development across frontend, backend, and infrastructure, and collaborate cross-functionally to deliver secure, reliable software. I’m currently contributing to the next generation of internal and operational software including a new platform and API core, and I enjoy UI/UX collaboration and delivering robust, maintainable systems.
