SERVICES
Custom Web and Mobile App Development Services
We design and ship production web and mobile products with React, Next.js and React Native, from a first MVP through to a platform serving hundreds of thousands of users.
Discuss your projectWe build custom web and mobile applications for founders and product teams who need to move fast without painting themselves into a corner. Our work spans React and Next.js web apps, cross-platform React Native mobile apps, and the full-stack backends behind them, with one engineer accountable for every line we deliver.
Every project is led directly by our founder, Gopal Sabhadiya, who is in the Toptal top 3%, Expert-Vetted on Upwork, and a former Infosys Specialist Programmer. With a focused team of 10 based in Surat, India, we serve clients worldwide in English, bill in USD, and overlap at least four hours with your timezone.
One codebase, both platforms
We build cross-platform mobile apps in React Native so iOS and Android ship from a single codebase, sharing the large majority of the code and cutting both timeline and maintenance cost.
MVP to scaled product
We have taken products from first prototype to real scale, including USP.org's authentication microservice serving 500K+ users on horizontally scalable Spring Boot.
Founder on every project
Gopal Sabhadiya (Toptal top-3%, Expert-Vetted on Upwork, ex-Infosys) leads architecture and code review on every engagement. He is hands-on through delivery, not a name on the proposal.
Back-end and front-end together
We pair React/Next.js front-ends with Java/Spring Boot, Python, or Node back-ends, plus API integration, headless CMS, and AI/RAG where it earns its place.
Fast time to market
Next.js App Router, TypeScript, and reusable component systems let us turn validated ideas into shippable software quickly, with rapid prototyping built into how we work.
Worldwide, USD-billed, timezone-aligned
We work in English, bill in USD, and overlap 4+ hours with any timezone, with a 100% client-satisfaction record to date.
Cross-platform mobile apps with React Native
As a React Native app development company, we build iOS and Android apps from one shared codebase, written in TypeScript, with native modules added only where a feature genuinely needs them. In practice most of the code is reused across both platforms. For most startups this is the difference between maintaining one team and one codebase versus two of everything.
React Native is well suited to MVP development because it lets you validate on both app stores at once, then keep the same codebase as the product grows. A React Native app can absolutely scale from MVP to enterprise; the architecture decisions we make early, around state management with Redux, modular navigation, and clean API boundaries, are what keep it maintainable as features and users multiply. Where a workload truly demands platform-specific performance, we are candid about it and design a hybrid approach rather than forcing one tool to do everything.
Custom web applications with React and Next.js
Our Next.js development services cover everything from marketing sites to complex SaaS platforms. We use the Next.js App Router with server-side rendering (SSR) and static site generation (SSG) to deliver fast, SEO-friendly, mobile-first responsive web apps, typically deployed on Vercel. The result is scalable product architecture that performs well for both users and search engines.
A concrete example is Bar.Stream, a hospitality automation platform we built on a Java/Spring Boot backend with a React/Next.js frontend. It serves 200+ B2B customers, has generated roughly $500K in revenue, and uses RAG for product size identification and classification so bars and restaurants get complete, automated inventory reporting. We bring that same full-stack discipline, including headless CMS and API integration, to custom web application development of any size.
From startup MVP to enterprise scale
We are a product development agency for startups, but the systems we build are engineered to outlast the MVP stage. For USP.org (United States Pharmacopeia) we built a Spring Boot and Spring Security authentication microservice that is horizontally scalable and supports 500K+ users, the kind of enterprise-grade application foundation that lets a product grow without a rewrite.
We also build AI into products where it creates real value rather than novelty. Invoxbooks.com is a Python platform we built that combines AI invoice parsing, plumbing work management, vendor comparison, and order management, using RAG, and saves the client roughly $200K per month. Whether your next step is MVP validation or scaling an existing platform, we right-size the architecture to where you are and where you are going.

Frequently asked questions
How much does it cost to build a React Native app? +
React Native app development cost depends on scope, the number of screens, integrations, and whether you need a backend. Building cross-platform from a single codebase is typically cheaper than building separate iOS and Android apps because you maintain one codebase. We bill in USD and scope each project after understanding your feature set, so share your requirements and we will give you a concrete estimate rather than a generic number.
Is React Native good for MVP development? +
Yes. React Native is one of our preferred choices for MVP development services because it ships to iOS and Android from one codebase, shortening time to market and reducing cost. Just as importantly, you keep that same codebase as the product matures, so a React Native MVP can scale into a full enterprise app without starting over.
React Native vs native app development: which is better for startups? +
For most startups, cross-platform React Native wins because you get both platforms from one codebase, faster, with most of the code shared. Fully native makes sense when an app is built around heavy platform-specific performance or hardware features. We assess your specific requirements and recommend honestly, including a hybrid approach when that serves you best.
What is the difference between React and React Native? +
React is a JavaScript library for building web user interfaces that render in the browser. React Native uses the same component model and developer experience to build real native mobile apps for iOS and Android. They share concepts and a lot of logic, which is why a team fluent in both, like ours, can move efficiently across web and mobile.
Why use Next.js for custom web application development? +
Next.js gives you server-side rendering and static site generation out of the box, which means fast load times, strong SEO, and a structure that scales from a landing page to a full SaaS platform. With the App Router, TypeScript, and Vercel deployment, it is our default for custom web application development, as on the Bar.Stream platform serving 200+ B2B customers.
