Michael Spahr.
I build production-grade AI systems end to end — SaaS apps, RAG pipelines, agentic workflows. No demos that crumble; no handoff at prototype. Shipped across healthcare, industrial, finance, and enterprise environments.
01—what i do
What I build.
AI SaaS, end to end
I build the AI core and the full product around it — RAG pipelines, document processing, agentic workflows — with everything that makes it shippable: frontend, backend, database, multi-tenant auth, deployment. One owner, spec to production.
AI integration
Already have a product? Let's enhance it with AI — semantic search, structured extraction, classification, content generation — without a full rewrite. Clean integration into your existing stack.
Workflow automation
n8n, Make, and Zapier pipelines that glue your tools together — CRM, email, Slack, databases — with LLM steps for triage, tagging, and routing. Replacing hours of manual, repetitive work every week.
Audit
A structured look at what's already built — code quality, security exposure, AI/LLM cost and reliability, or due-diligence-grade review for an acquisition. You get a prioritized list of what to fix and what's fine to leave.
Strategy & advisory
Not sure where AI fits in your business? I'll map the high-leverage use cases, assess feasibility and cost, and help you decide build vs. buy — before you commit to anything. You get a roadmap you can act on.

03—selected work
A few things I've shipped.
2026
AI-augmented operations workflow
n8n-orchestrated automation tying together a team's everyday stack — inbox, CRM, Slack, and a Postgres source of truth. Inbound messages are classified and enriched by an LLM step, routed to the right owner, and logged with structured context. One deployment cut ~15 hours of manual work per week and reduced processing time by 70%.
2025
Multi-tenant RAG platform
SaaS chatbot platform that lets non-technical clients configure a knowledge base, embed a JS widget on their site, and get streaming, source-aware answers — without touching code. FAISS for vector search, JWT with refresh-rotation, isolated per-tenant data, Next.js admin dashboard for self-serve onboarding.
2025
AI document processing pipeline
End-to-end pipeline that turns unstructured documents — invoices, contracts, reports — into clean structured data. LLM-driven extraction pulls the fields that matter, a human-in-the-loop validation step keeps it reliable, and a report generator produces polished PDFs on the other side. In one healthcare deployment, this eliminated 40 minutes of manual work per report across 1,500 annual reports.
2020
Trading analytics & ML forecasting
Built data and trade analytics tools for the Swiss credit and rates trading desk — visualizing market dynamics, aggregating Swiss trading data into a queryable database, and delivering a web interface for interactive trader support. Developed time series models and applied ML techniques to forecast Interest Rate Swap valuations, producing quantitative signals to support trading desk decisions.

05—about
A bit about me.
I’m a Swiss AI engineer based in Sion, Valais — trained at EPFL (Computer Science) and ETH Zurich (Computational Biology and Bioinformatics) — who works as a generalist that goes deep. I own projects end-to-end, from early product thinking through backend architecture, AI integration, and cloud deployment, with a focus on applied AI: retrieval pipelines, document understanding, agentic workflows.
I’ve shipped systems across healthcare, finance, industrial, and enterprise environments — research in genome sequencing analysis at ETH, an AI-driven report-generation pipeline for a private healthcare clinic, trading analytics and ML forecasting for Credit Suisse’s rates desk, and RAG and automation platforms at Neuralia and Group Mutuel — both within teams and as an independent consultant.
I start by understanding user needs and business context before writing any code. Combined with a rigorous engineering foundation and a Swiss mindset around reliability and precision, this means clients get systems that actually work — and that people actually use.
I use the same tools I build with in my own workflow — AI and automation as a force multiplier, not a shortcut. Clients get the pace of a team from a solo consultant.
