    Why Hire Them?

    • They offer a cohesive stack: because NoraBytes also handles software, web and eCommerce development, they can design APIs that are tightly integrated with those layers rather than being bolt-on.
    • Romania’s talent base means you can potentially access high-quality backend engineering API architecture, security, and scalability at a more favourable cost-to-quality ratio compared to many Western European vendors.
    • Having a firm that knows both the API layer and the consumer-facing parts reduces the risk of misalignment, hand-off issues or integration bottlenecks.
    • Suppose your project requires microservices, B2B APIs, SaaS platform interfaces, or complex data flows between systems, for example, eCommerce + ERP + mobile app. In that case, NoraBytes’ dedicated API development capability gives you a specialist focus rather than a generalist.
