Skills
Künstliche IntelligenzNode.jsNoSQLNext.jsTypeScriptWeb Application DevelopmentChatbotsBackendReact NativeFront End
Full-stack developer with a strong focus on React-based web applications, Node.js backends, and React Native mobile apps (with and without Expo).
In addition to traditional development, I build AI-powered applications — including custom chatbots using Retrieval-Augmented Generation (RAG), LLM integrations, and AI agents for automation and workflow optimization.
Technical experience includes:
- SQL & NoSQL databases (PostgreSQL, MongoDB, etc.) and related tools (Sequelize, Mongoose)
- Cloud platforms such as Amazon Web Services, Google Cloud Platform, and Vercel
- Serverless architectures and scalable backend systems
- CI/CD and DevOps with GitHub Actions and Jenkins
I have experience leading frontend teams in high-quality production environments and focus on building reliable, maintainable systems — now increasingly enhanced with modern AI capabilities.
If needed, I can also provide a small, trusted team of developers and testers for larger projects.
