We build web and mobile applications for:
We use shared design systems, component libraries, and consistent API contracts. For mobile, Flutter and React Native allow code reuse while maintaining native performance. We test on multiple devices and screen sizes, implement responsive design patterns, and ensure feature parity where it matters most.
Yes. We implement WebSockets for web apps, GraphQL subscriptions for flexible data streaming, and push notifications for mobile. Backend services use event-driven architecture with Kafka to ensure real-time updates are delivered reliably, even under high load. We handle connection management, reconnection logic, and offline queuing.
We implement secure authentication with JWT tokens, OAuth providers (Google, Apple), and session management. For payments, we integrate Stripe and Paddle with webhook handling, subscription management, usage-based billing, and compliance with PCI DSS requirements. All sensitive operations are handled server-side.
Flutter uses Dart and compiles to native code, offering excellent performance and consistent UI across platforms. React Native uses JavaScript and native bridges, allowing easier integration with existing web codebases. We choose based on team expertise, performance requirements, and long-term maintenance plans.
We will audit your existing product, identify bottlenecks, and design a scalable architecture that supports your next stage of growth. Let's build an application your users will love — and your team can scale.
