I'm Matteo Guarnerio — Head of Solution Architecture at SIX Group, NLP patent holder, and the architect behind mission-critical AI systems at Switzerland's largest banks and exchanges.
I help enterprises and high-growth companies cut millions in recurring costs, escape vendor lock-in, and ship AI that actually runs in production — not just in a demo.
First call is free. No pitch decks. No fluff. Just an honest conversation about your problem — and what it would take to solve it.
⚡ Limited to 3 new engagements per quarter — currently accepting Q4 2026
Delivered for the world's most demanding institutions
The Problem
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
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.
What I Do
From strategy to production. No hand-waving — only solutions that run in the real world.
Methodology
We define one measurable business outcome — cost to reduce, process to automate, or risk to detect. No scope creep, no vague mandates.
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.
Architecture blueprint, technology stack selection, build-vs-buy decisions — all documented and reviewed before a single line of code is written.
Tight sprints. Working software validated against real business metrics — not Jupyter notebooks. Full ML pipeline from ingestion to inference.
Zero-downtime go-lives. Runbooks, monitoring, and knowledge transfer so your team owns it after I'm gone.
Proof of Work
Mission-critical delivery at Switzerland's top financial institutions.
Leading the modernisation of Switzerland's core exchange infrastructure.
Currently driving the Equinox programme within the Polaris strategic initiative — harmonising and modernising the BME and SIX Swiss Exchange core trading platforms. Responsible for solution architecture governance, vendor strategy, and the technology programme across all workstreams, setting the direction for the Swiss financial market infrastructure for the next decade.
550,000 accounts migrated in a single weekend. Zero incidents.
Led the end-to-end architecture and delivery of FISCA 2.0, migrating the full BVG (2nd pillar pension) portfolio — over 550,000 client accounts — for the largest asset manager in Switzerland. The entire cut-over was executed over a single weekend with zero downtime and no impact to end-users, setting a new standard for large-scale migration at UBS.
Real-time AML, fraud prevention & KYC — built on Palantir.
Architected and built the Single Client View platform on top of Palantir Foundry, aggregating data from dozens of internal systems to give compliance and risk teams a real-time, 360° view of each client. The platform powers instant AML signals, fraud detection, and sophisticated KYC workflows driven by machine learning pipelines and advanced data engineering.
About
I'm Matteo Guarnerio — currently Head of Solution Architecture and Head of Program & Technology at SIX Group Services AG, where I lead the modernisation of the Swiss core exchange infrastructure. With 17+ years delivering at the intersection of finance and technology, I know what it takes to ship at scale in a regulated environment.
I've held technical leadership roles at Credit Suisse, UBS, Zurich Insurance, and PostFinance. I hold a granted Italian patent in unsupervised NLP summarization (ITUA20164325) and have applied ML and advanced data engineering in production systems handling billions in assets. I only build things that work in the real world.

Work With Me
Whether you need a quick architecture review or a full AI programme delivery — there's a way in. Every engagement starts with a free call.
⚡ 3 slots available · Q4 2026
From CHF 2,500
A focused 2–4 hour deep-dive into your architecture, data, or AI roadmap. You walk away with a written diagnostic and a prioritised action plan you can execute internally.
Scope-based
End-to-end ownership of an AI, automation, or migration initiative. From architecture to production. I embed in your team and ship — with zero fluff and full accountability.
Monthly retainer
Ongoing senior architecture and AI leadership without the full-time price tag. Ideal for companies scaling fast who need board-level technical guidance and a trusted execution partner.
Submit Your Project
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.
Skin in the Game
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
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.
