REACT NATIVE DEVELOPMENT




A technology development company supports businesses by planning, building and maintaining digital products that solve real operational needs. This includes understanding user behavior, device limitations, performance requirements, and future scalability. Development teams must balance design, functionality and stability while ensuring applications remain easy to update. When these factors align, products remain reliable, adaptable and useful throughout their lifecycle.
React Native is widely used for mobile application development because it balances speed, consistency and performance across platforms while reducing overall development effort.
React Native allows a single codebase for Android and iOS applications. This reduces development time, minimizes duplication and ensures consistent behavior across platforms.
Applications built with React Native use native components, delivering smooth interactions and familiar interface behavior expected by mobile users.
Reusable components and hot reloading speed up development and testing, allowing teams to deliver features and updates more efficiently.
With shared logic and centralized updates, ongoing maintenance becomes easier, reducing long-term support complexity and costs.

Eternalight really knows the travel space. They helped us at Navan hook up backend systems for both LCC and non-LCC airlines in India, plus integrate with hotel content providers. Super quick turnaround, solid quality — exactly what we had in mind

We were looking for a partner who could strengthen our existing team and bring deep expertise in the fintech domain. We needed 10+ skilled engineers on short notice—people who understood both fintech and product development.

Jayesh Gadewar
Co-Founder
Our product has evolved over 8 years, built by a mix of developers, freelancers, and myself. But with outdated technology and legacy code piling up, we started facing major challenges—slow performance, upgrade issues, and poor scalability.

Anita Balaraman
Founder
We had a fast-moving idea for an AI-based product and needed a skilled frontend engineer to build a scalable, responsive interface within 3–4 weeks. Having worked with Eternalight before, choosing them again was a no-brainer. As expected.
