The Problem

Most companies are drowning in cost, not AI potential.

Paying CHF millions per year in licensing fees for legacy tools like UC4 Automic that open-source solutions like Apache Airflow handle better — for free.

Running fragmented data silos that block real-time fraud detection, AML compliance, and single-client views of financial risk.

Funding expensive 'AI experiments' that never reach production because the data engineering and architecture weren't right from day one.

Locked into vendor ecosystems that held your IT budget hostage instead of delivering competitive advantage.

The Solution

Senior expertise. Production-grade. Measurable ROI.

Architect and deliver migrations from costly proprietary tools to enterprise-grade open-source platforms — validated at tier-1 banks.

Build end-to-end ML pipelines and data engineering foundations that turn fragmented data into instant, actionable intelligence.

Design AI systems for AML, fraud prevention, and KYC that operate at the scale of Switzerland's largest asset managers.

Deliver on time, on spec, and in production — with a track record of zero-downtime migrations and flawless weekend go-lives.

Methodology

How I Deliver

01

Discovery & Business Hypothesis

We define one measurable business outcome — cost to reduce, process to automate, or risk to detect. No scope creep, no vague mandates.

02

Data & Architecture Audit

I audit your current data landscape, infrastructure, and toolchain against the target use case. This is where the ROI case is built or killed early.

03

Solution Design

Architecture blueprint, technology stack selection, build-vs-buy decisions — all documented and reviewed before a single line of code is written.

04

Build, Verify, Iterate

Tight sprints. Working software validated against real business metrics — not Jupyter notebooks. Full ML pipeline from ingestion to inference.

05

Production Deployment & Handover

Zero-downtime go-lives. Runbooks, monitoring, and knowledge transfer so your team owns it after I'm gone.

I read every submission personally. If there's a fit, I'll respond within 48 hours to schedule a call. No sales team. Just me.

Treated with full confidentiality. NDA available on request.

Skin in the Game

Great ideas shouldn't die because of budget.

If you have a compelling problem, a real market opportunity, and the drive to execute — but limited capital — I'm open to a different deal. I'll contribute senior architecture, hands-on AI engineering, and strategic mentorship in exchange for an equity stake or a revenue-sharing agreement.

This is not charity. I'm selective — I take maybe 1–2 of these per year. The idea needs to be genuinely differentiated, the team needs to be serious, and the business model needs to make sense. If that's you, make your case.

FAQ

Common Questions

Do you work with companies outside Switzerland?

Yes. My primary market is Switzerland, DACH, and the EU financial sector, but I work remotely and travel for the right engagement.

How do engagements typically start?

With a 30–60 minute strategy call to understand your situation, goals, and constraints. No commitment required. I'll be direct about whether I can add value.

What size of company do you work with?

I've worked at the very top — tier-1 banks managing trillions in assets. I also work with high-growth startups where the business case is strong and the team is serious.

Can you work under NDA / confidentiality?

Absolutely. I operate under strict confidentiality and am accustomed to the data security and compliance standards of regulated financial institutions.
