Our Work, In Their Words

Hear directly from our clients as they share how our work made a real impact on their business.

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
Thiagarajan Rajagopalan
Vice President of Products
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.
Rizwanul Haque
Senior Director Of Engineering
I had a frustrating experience with another company while building my product and was looking for a partner who truly understood what it takes to build something great. That’s when I was referred to Eternalight—and I was immediately impressed by their portfolio.
Pravat Lall
Founder, CEO
We needed a team that truly understood the sports domain and had real experience building event-based reservation systems. Eternalight stood out because of their past work in the space. We had an ambitious goal to launch our MVP in just 2 weeks
Abhinav Shankar
Co-founder
EternaLight proved to be the ideal choice. Their team of developers demonstrated exceptional skill and dedication, seamlessly integrating with our existing processes and upholding our high standards. Their ability to adapt to new frameworks
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 But with outdated technology and legacy code piling up, we started facing major challenges—slow performance, upgrade issues, and poor scalability.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.
