Services
Data
Databases, pipelines, models and warehouses, then the dashboards built on them. Every figure keeps its definition, its owner and its source, on PostgreSQL, SQL Server, BigQuery or Snowflake for instance, sized to the need.
See the details →Applications and integration
Web, mobile and desktop applications, business tools, APIs and automation: the software missing between your software, written in whatever language the need dictates, tested, connected to what exists and delivered with its documentation.
See the details →Azure and Google Cloud
Architecture, migration and operations on Azure and Google Cloud, or with a Swiss host when the file calls for it. The infrastructure is described in code, every cost has an owner and every cutover has a tested rollback.
See the details →Servers and hosting
Active Directory, Exchange, Microsoft 365, Google Workspace, kSuite, private or dedicated servers: I build them, integrate them with identity and backups, then operate them with role-based access, tested restores and a monthly report.
See the details →Artificial intelligence
Assistants that cite your documents, agents that run a bounded task, document extraction, and the infrastructure serving them: an open model on your machines, Swiss hosting or a cloud provider's API, chosen after reviewing the data and the contract.

A first conversation, no commitment
A few lines about your project or your question are enough: I reply directly, usually within one working day.
Two ways in
Enterprises and institutions
Six sectors with their constraints, the systems to build and the projects that relate to them.
See the sectors →SMEs and organisations
Shops, workshops, schools, laboratories, associations and law firms across French-speaking Switzerland: the needs I take on, in their own words.
See the organisations →
The systems I build
A selection of the systems described on this site, each built for one organisation and delivered with its code and documentation. No licensed product.
The data foundation
Your sources reconciled in a governed model, with definitions, owners and controls.
See →Secure AI assistants
An assistant evaluated on your documents, with sources, permissions, processing and retention written down.
See →Private AI infrastructure
An open model served on your machines or with a Swiss host, or a gateway to a cloud provider's APIs, sized and measured on your documents.
See →Migration to hosting you chose
Server, files or mail moved to an evidence-based choice, with rollback and exit defined.
See →Versioned infrastructure
Azure, Google Cloud or Proxmox infrastructure described in versioned files, with reviewed changes and a testable rebuild.
See →Identity, directory and access
One account per person, rights carried by groups, technical secrets inventoried and revocations you can verify.
See →The business tool built for you
The spreadsheet that runs the company, turned into a real application.
See →Business agents
Tasks chained end to end, with a person at the points that matter.

Applied AI
Three demonstrations open to anyone, with nothing to install and nothing to sign. Judge the work on evidence.
The site assistant
Answers from the site’s own pages and cites its sources. Model, latency and tokens shown with every reply.
Four-language mail
Dialect, Romansh, Italian, German. Translation plus the actions to take, on open models.
Research watch
The OpenAlex catalogue queried in plain language. Object, method and result summarised for each study.

How I work
First conversation
No commitment. You describe your situation; I tell you honestly whether I can help.
Assessment
A review of your IT and your data, then a prioritised roadmap. The scope and the price are agreed with you before the work starts.
Project
Scope, schedule and price agreed up front, based on the roadmap.
Ongoing support
A monthly operations retainer: monitoring, maintenance and controlled change.
Latest articles
- Cloud access on Google Cloud, Azure, AWS and Infomaniak
The same four decisions on four platforms, and an honest account of the gap: Infomaniak gives you Swiss residency and OpenStack portability, and gives you no inherited permissions, no device-aware sign-in rules and no expiring administrator role.
- The EU AI Act now applies: four questions for a Swiss company
A Swiss address does not settle whether the EU AI Act applies. Start with the company’s role, the EU connection, the effect on people and the evidence needed before production.
- Five threats to a Swiss organisation, and the control that blocks each one
Documented Swiss incidents point back to the same controls: exposed services, identity, payments, suppliers and recovery. The order still needs to fit the organisation's risk.
