Production AI features for SaaS teams and agencies —shipped end-to-end by one engineer who's accountable for the whole stack.
Most “AI integrations” fail because they're built by prompt engineers without product experience, or backend devs who can't ship a polished UI. I build the data layer, the AI logic, the API, and the frontend — and I ship it.
What I build
RAG Chatbots
Custom chatbots that answer questions from your docs, knowledge base, or proprietary data. Supabase pgvector + Python + LLM.
Pilot from €6,500 → full build
AI Semantic Search
Replace keyword search with embeddings-based semantic retrieval. Find “what users mean” not “what they typed.”
From €4,000 · 3 weeks
AI Assistants with Memory
Domain-specific AI assistants for support, sales, ops, or internal tools. Persistent context, structured outputs, real workflows.
From €5,000 · 4 weeks
AI-Powered Internal Tools
Dashboards, admin panels, automation pipelines that wrap LLMs into actual business workflows.
From €6,000 · 4–5 weeks
Low-commitment entry point
Start with a paid RAG Pilot
€6,500 · 3–4 weeks
Not ready to commit to a full build? The pilot proves the system on your own data: a working assistant on one of your doc sources, plus an accuracy report on 100 real support tickets — with zero hallucinations on your red-flag set. The fee is credited to the full build if you proceed within 30 days.
See the RAG ladderThe stack I use
I deliberately work with this stack because it's reliable in production, cheap to host, and easy for your team to maintain after handoff. No vendor lock-in to obscure AI infrastructure.
Data layer
Supabase (Postgres + pgvector + Auth + Storage)
AI layer
Python (FastAPI), OpenAI API, Claude API
Frontend
React + Vite + Tailwind / React Native
Deployment
Vercel + Railway / Render

I don't work on: deepfakes, scraping projects, get-rich-quick content farms, or anything that competes with my existing agency partners.
