Production-ready AI agents, mobile apps, and web systems.

Our tech stack is built for production-ready products where AI agents, mobile apps, and web systems keep working as one unified unit after launch: frontend, CI/CD, updates, tests, releases, new features, new data, and new AI workloads.

React Native and Expo power mobile. React and Vite power web. Google Agent Development Kit (ADK), Vertex AI, and Google Cloud Platform (GCP) power deterministic AI agent workflows, tools, runtime, and scaling.

Between them sits shared TypeScript logic: architecture patterns, state management, headless UI primitives, design systems, CI/CD, quality gates, observability, and technical debt prevention.

The result is a highly efficient single-codebase strategy — less drift, consistent UX on mobile and web, clear quality gates, and AI agent workflows designed for production from the start: modular, maintainable, and durable.

Mobile App Development with React Native & Expo

React Native and Expo combine shared TypeScript logic, native performance, App Store delivery, and mobile security in a production-ready architecture. The industrial standard powers companies such as Meta, Amazon, and Tesla — and shares most product logic with our web systems.

Cross-Platform App Development: One TypeScript codebase carries UI patterns, state management, validation, API contracts, and business logic across iOS and Android. Shared modules, design tokens, and tested UI patterns make both platforms feel like one product — not two separate apps.

Mobile App Performance: Hermes, the New Architecture, Worklets, and targeted native modules are used where startup time, gestures, animations, or device APIs are critical. Performance budgets, profiling, and native bridges keep cross-platform apps fluid even in demanding flows.

Expo – The Modern Way: As a framework, we rely on Expo, the leading ecosystem for React Native — not as a simple toolkit, but as a professional tooling layer in the managed workflow. Builds, preview distribution, over-the-air updates, and native modules are operated in a structured way so releases stay predictable and repeatable.

Mobile App Security: Secure storage, permissions, deep links, auth boundaries, and API protection are placed into the architecture early. Token rotation, certificate pinning, and clear session boundaries keep mobile security reliable in production operations.

Market Standard & Security: We rely on the industrial standard supported by technology leaders such as Microsoft and Shopify. This secures a stable, future-proof ecosystem, long-term maintainability, and maximum technological independence.

Cost Efficiency: Instead of funding two separate teams for iOS (Swift) and Android (Kotlin), we develop business logic centrally in TypeScript. This typically reduces initial development costs by 40% to 70% — while preserving native quality on both platforms.

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.
