I'm an AI Software Engineer with huge experience software engineering experience, combining production AI/LLM development with a strong Python backend foundation.
I build GenAI systems that go beyond prototypes: RAG pipelines, AI agents, LLM orchestration, vector search, natural-language-to-SQL workflows, and the backend services required to run them reliably in production.
My recent work includes building a LangGraph-based data agent for real estate analytics, architecting a production multi-agent AI system, and developing RAG solutions over large document collections.
I work across the full AI application lifecycle — from architecture and model integration to APIs, asynchronous processing, databases, containerization, deployment, monitoring, and evaluation.

Project history
Building Data Agent, an AI-powered analytics system for the Swiss real estate market.
Designed and built the system end to end, enabling users to ask questions in English, German, or French and receive SQL-backed answers, interactive charts, and analytical reports.
Architected a LangGraph orchestration pipeline covering query classification, schema linking, SQL generation and execution, dashboard navigation, and KPI workflows.
Built structured analytics and tearsheet reporting for real estate funds, investment foundations, and companies.
Implemented deterministic financial calculation logic while restricting LLM usage to commentary and plain-language explanations.
Developed and deployed the production stack using Python, FastAPI, PostgreSQL, Azure OpenAI, Docker, and Azure.
Designed and built a production RAG system over large tax document collections.
Developed Python/FastAPI services using
PostgreSQL, Redis, vector search, and REST APIs.
Owned retrieval quality and evaluation and collaborated with data engineers on document ingestion pipelines.
Built internal automation tools that removed repetitive reporting work and saved the team hours each week.
Deployed and monitored services using Docker and cloud infrastructure.
Delivered production systems including a digital content platform, an Al support assistant, and a Telegram job-matching application.
Built Python/FastAPI backend services with PostgreSQL and MongoDB.
Integrated LLM functionality for context-aware support, including prompt design, logging, and evaluation.
Built React/TypeScript interfaces and deployed applications to AWS and DigitalOcean.
