About Oskar

Are you wasting time on tasks that AI could handle for you?
I build AI automation systems for Swiss and French-speaking SMEs: voice agents that answer the phone 24/7, chatbots trained on your internal documents, and automation pipelines that replace hours of manual work.
What I deliver concretely:
AI Voice Agent — Your customers call, an AI qualifies them, makes appointments, and sends you a summary by email. Zero missed calls, even at 3 AM.
RAG Chatbot on your data — An intelligent assistant integrated into your website or Telegram, trained on YOUR documents (FAQs, PDFs, catalogs). Instantly answers your customers or your team.
Scraping & Data Pipelines — Automated competitive intelligence, lead generation, data extraction from any website.
Why me instead of an agency:
I code everything myself in Python (FastAPI, Docker, LangChain) and deploy on European servers — your data stays in Europe, GDPR compliance guaranteed. No fragile no-code that breaks at the first edge case. No intermediaries. Direct communication, fast delivery.
Computer Science student at EPFL (world's #1 engineering school), I master LLM APIs (Gemini, Claude, GPT), vector databases (ChromaDB), and Docker deployment on VPS. Quadrilingual: French, English, Spanish, Portuguese — I build multilingual AI systems natively.
Types of missions: Customer chatbot setup, voice agent for medical practice/real estate agency, internal workflow automation, AI integration into existing tools, consulting on AI adoption.
