Developer Studio for AI, Apps & Web Apps

Development of iOS, Android and Web applications with AI technologies.

Services

We build holistic end-customer solutions that form their own, closed, digital ecosystem.

Our 'sweet spot' is the fusion of mobile apps (iOS & Android), marketing and landing pages, controlling web platforms (dashboards, CRMs), and intelligent AI automation.

This approach is particularly valuable for digital products and services where the customer frontend (app/web) communicates seamlessly and in real time with the operations backend – without the frictional losses of separate software silos.

Core Competencies

Mobile Apps with
React Native &
Expo

We develop mobile applications for iOS & Android that feel and behave 100% native.

Technology: React Native and the Expo framework on a consistent, type-safe TypeScript codebase.

Performance: Targeted inclusion of native modules and the Hermes engine for a smooth 60 fps UI/UX.

Efficiency: Features are developed once and rolled out simultaneously on both platforms – this shortens the time-to-market and halves the maintenance effort.

Web Applications with
React &
Next.js

Modern scalable, high-performance, and interactive web architectures that go far beyond static pages.

Technology: React with Vite and Next.js - if required: Turborepo, if a monorepo (a single repository for several projects) is required.

Scope: Dynamic web apps, complex admin panels, dashboards, and CRMs for controlling the applications.

Synergy: Up to 60%–80% code sharing between web and mobile guarantees consistent business logic on all screens.

AI Agents & Agent Systems with
Google ADK &
Vertex AI

We integrate AI deeply into your process chain – as a central engine for automation.

Technology: Google's Agent Development Kit (ADK) in Python, Vertex AI, LLM orchestration, MCP, A2A, A2UI

RAG & Vector Search: We make company data searchable and usable for AI ("grounding").

Autonomous Agents: Multi-agent systems that execute complex workflows (analysis, decision, database operations) autonomously.

Cloud Infrastructure with
Google Cloud Platform (GCP)

Scalability is not a coincidence, but planning. We build exclusively on enterprise-grade infrastructure.

Serverless First: Cloud Run and Cloud Functions for automatic scaling during load peaks.

Data Backbone: High-performance data storage with Firestore (NoSQL) from Firebase for real-time sync or Cloud SQL (PostgreSQL) for complex relations.

Security: Central authentication (IAM) and strict data separation. Use of Cloud CDN and Cloud Armor as a global shield.

The All-in-One Advantage

Our strongest performance is not the sum of individual components, but their seamless integration. We bundle mobile apps, web applications, and AI systems in a common architecture with a unified code base.

  • eliminates data silos and redundant logic

  • significantly reduces development and administration costs

  • creates a consistent user experience on desktop and mobile

By combining modern React frontend technologies with scalable backend infrastructure, integrated AI agents, and cloud-native architecture, we create:

  • automated, intelligent workflows

  • high-performance, maintainable systems

  • an intuitive UI/UX with stable high performance

The System Advantage in Detail

Real-time Synchronization: User data, profiles, and states are synchronized in real time between mobile app (React Native), web app, and dashboard (React). No delays, no double data storage.

Central Control: Content, user rights, and business rules are centrally controlled via a tailor-made admin panel. Changes can be rolled out immediately to all end devices via over-the-air update – without app store detours.

Integrated Intelligence: Our AI agents are not an add-on but part of the system. They access the central data backbone directly, automate processes in the background, and make results immediately visible in app and web.

Single Source of Truth (SSOT): One backend. One database. One logic. Instead of connecting three fragile systems via interfaces, we build a robust platform that reduces complexity and enables growth.

We do not develop isolated apps. We create scalable corporate values. Through this approach, we reduce development costs by 40–70% compared to separate individual developments – while at the same time massively reducing maintenance effort.
