Freelancer for LLM Systems, Backend Architectures & Modular Frontends
I am a computer science graduate with over 10 years of experience in developing complex software systems – from industrial image processing to modern AI and web applications. My focus is on data-driven systems with Large Language Models, robust backend foundations, and easily integrable AI frontends.
LLMs, AI Agents & RAG Workflows
I develop production-ready LLM applications with LangChain, LangGraph, and vector databases. Application areas: Retrieval-Augmented Generation, semantic search, tool use, and automated knowledge processes.
The focus is on the reliable connection of internal and external data sources (e.g., SQL, APIs, file systems) as well as the construction of modular agents with clear logic and iterative prompts.
Backend Architectures with TypeScript & Python
I realize efficient backends with a focus on data integration, interface management, and AI preprocessing – whether microservices, MQTT connectivity, or CI/CD pipelines.
Technologically, I prefer to work with TypeScript and Python. Stability, extensibility, and clear architecture are paramount.
Modular Frontends with Svelte & WebComponents
For interactive UIs, I develop modular frontends with Svelte, TailwindCSS, and TypeScript – expandable with WebComponents that can also be integrated into React or Vue.
The focus is on AI-related interfaces such as semantic search, input workflows, or dynamic visualizations – performant, maintainable, and without unnecessary overhead.
C++ & Industrial Image Processing
My technical background is in industrial C++ software for image processing, sensor technology, and embedded AI – such as LiDAR fusion, segmentation, or optical quality control.
This experience gives me a deep system understanding – particularly valuable in hybrid projects where classic sensor technology meets modern AI.
