Overview
Ahmedabad-based fintech startup serving 2,000+ merchants faced a slow growth trajectory due to a fragmented mobile experience, separate native apps, and rising maintenance costs from a multi-vendor stack. The business needed a faster time-to-market, predictable costs, and a single, reliable mobile experience for customers and merchants. Our India-based delivery team built a unified iOS and Android app using a modern, API-first backend. The solution we delivered leveraged Spring Boot for core services, Django for analytics, Laravel for the merchant portal, and a MERN-backed admin interface, while the mobile UI was React-based to ensure rapid iteration and consistency. This multi-stack approach enabled clean separation of concerns, scalable integrations, and rapid feature delivery through well-defined APIs. We rolled out in a phased manner: MVP in 8 weeks, followed by 4-week feature sprints, with CI/CD to accelerate deployments and reduce downtime. The project included integrated payments, loyalty, and analytics, plus an offline-capable mode and a simple onboarding flow to cut friction for merchants. Our team worked from India with a nearshore client liaison to ensure alignment and speed, minimizing rework and handoffs. The result was a cohesive, maintainable app that supports rapid scale across markets with a unified data model and reusable components. After six months, onboarding time dropped by ~60%, in-app conversions rose ~28%, and maintenance costs declined by ~32%, delivering clear ROI and a reliable platform for growth.
