appamass - AI Agents & App Development Studio

appamass develops production-ready apps with unified architecture so deterministic AI workflows collaborate across platforms on mobile and web.

We specialize in building productive AI agents with the Google Agent Development Kit (ADK). For mobile and web apps, we rely on cross-platform solutions with an efficient single-codebase strategy using React Native, Expo, and React with Vite.

Our agentic-coding-first approach with TypeScript and Python is a highly efficient tool in our engineering AI system. It only reaches its full impact through strict workflow discipline and our deep frontend expertise in app architectures.

Our standard is technical excellence paired with state-of-the-art agentic AI development and proven agentic engineering practice. We develop production-ready, unified app systems and mature app architectures with clear structure. In them, autonomous AI agents operate deterministically in mobile and web apps—seamlessly connected to relevant data, secure guardrails, and people as part of one shared workflow.

In AI, we build production-grade controllable multi-agent systems and graph-based agent workflows with the Google Agent Development Kit (ADK) in Python, Vertex AI, Google Cloud, and Google Cloud Platform (GCP): orchestration, tools, agent permissions, dynamic workflows and human-in-the-loop (HITL) gateways, observability, evaluation without hallucination risk, and an intuitive generative UI.

We rely on highly efficient cross-platform development with React Native, Expo, React, and Vite. This enables us to share 60%–80% of the code between native apps (iOS and Android) and the web: through shared modular product and TypeScript logic, clean state models, reusable components, robust primitive UI patterns, and clear state management.

As experienced senior software engineers, we reject "quick & dirty" and work according to the KISS principle—modular, maintainable, and durable.
