Hi, I'm Franziskus — full-stack AI developer

I specialize in building AI-powered applications that deliver real business value. From integrating LLMs and RAG systems to deploying vision models, speech-to-text, and text-to-speech solutions, I help businesses harness the full potential of modern AI technologies.

I work across the entire AI stack, from OpenAI, Anthropic, and Grok to AWS Bedrock and open-source models. My expertise lies in connecting LLMs with tools to create intelligent workflows that automate complex tasks and drive measurable results. I also leverage AI in my own development process to ship quality software faster.

Why work with me?

AI-First Development

I build intelligent systems using LLMs, RAG pipelines, and agentic workflows that solve real problems, not just AI for the sake of AI.

Speed Without Compromise

By leveraging AI tools in my development workflow, I ship production-ready features faster while maintaining code quality and best practices.

Full-Stack Expertise

From database design to frontend interfaces to AI model integration, I handle the complete stack so your AI features work seamlessly in production.

Real Business Value

I focus on building AI solutions that automate workflows, reduce costs, and create measurable impact, not just impressive demos.

My AI Toolkit

I work with the full spectrum of AI technologies, from leading LLM providers to vector databases and agentic frameworks. Here's what I bring to your project.

LLM Integration
