appamass - Tech Stack
AI Agents, Apps & Web Development Studio
We develop, deploy, and merge AI agents, iOS, Android & web apps
Modern. Scalable. Controllable.
Our tech stack is built for products that keep living after launch: updates, tests, releases, new features, new data, and new AI workloads.
React Native and Expo power mobile. React and Vite power web. Google ADK, Vertex AI, and GCP power agents, tools, runtime, and scaling.
Between those layers is the real work: architecture patterns, state management, design systems, quality gates, observability, and technical debt prevention.
The result is Architecture Efficiency: less drift, better UX for mobile and web, clear quality gates, and AI agent workflows designed for production from the start.

Mobile App Development with React Native & Expo
React Native and Expo are the most productive path to iOS and Android apps when shared logic, native performance, app store delivery, and mobile security are considered together – used by companies such as Meta, Amazon, and Tesla.
Cross-Platform App Development: One TypeScript codebase carries UI patterns, state management, validation, API contracts, and business logic across iOS and Android.
Mobile App Performance: Hermes, the New Architecture, Worklets, and targeted native modules are used where startup time, gestures, animations, or device APIs are critical.
Expo – The Modern Way: As a framework, we rely on Expo, the leading ecosystem for React Native. We use Expo not as a simple toolkit, but as a professional tooling layer in the managed workflow.
Mobile App Security: Secure storage, permissions, deep links, auth boundaries, and API protection are placed into the architecture early.
Market Standard & Security: We rely on the industrial standard supported by technology giants like Microsoft and Shopify. This guarantees a stable, future-proof ecosystem and maximum technological independence.
Cost Efficiency: Instead of funding two separate teams for iOS (Swift) and Android (Kotlin), we develop the business logic centrally. This typically reduces initial development costs by 40% to 70%.
Focus on UX: Through the shared codebase, we can focus on developing a consistent, high-quality user experience. Good UX explains state, prevents user errors, and makes recovery possible even when the network, data, or agent output is not perfect.
