Independent IT consultant & developer

Clear systems.Operations that hold up.

I help organisations in Switzerland and abroad design, connect and strengthen their IT — from networks and business systems to digital dictation, custom software and algorithms.

Let’s discuss your projectSee how I work

An end-to-end view

Your IT should support the business — not force the business to work around it.

I take ownership where responsibilities overlap: networks, endpoints, servers, business systems, digital dictation, software, data and suppliers. The outcome is always the same — less friction and more control.

How I work

Understand before installing. Simplify before adding.

I can solve a well-defined issue or take technical ownership of an entire project. Either way, decisions remain transparent and the business stays in control of its system.

  1. 01

    Clarify

    Map the current setup, dependencies and real business need. Identify the risk before choosing the solution.

  2. 02

    Design & deliver

    Choose a proportionate architecture, implement it and test the scenarios that genuinely matter.

  3. 03

    Stabilise & hand over

    Document, monitor and enable the team. Remain available when real-world operations require it.

Hands-on experience

Proven experience where IT directly supports critical operations.

Healthcare, legal professions, hospitality, finance and international organisations: different environments where continuity, confidentiality and quality of execution are decisive.

01

Healthcare, legal & justice

Digital dictation expertise developed since 2005.

Since 2005, I have designed, migrated and supported dictation and speech-recognition workflows for medical practices, clinics, hospitals, and legal and judicial institutions.

Dictation · speech recognition

02

Hospitality & restaurants

Locations that must keep running during service.

Lightspeed points of sale, local networks, Wi-Fi, devices, remote access and continuity across multiple venues.

Multi-site operations

03

Finance & quantitative work

From raw data to an actionable decision.

Algorithm development, controlled automation, data processing and tools built for sensitive workflows.

Reliability & traceability

04

International operations

Systems that stay coherent across borders.

Infrastructure and integrations for organisations operating across Switzerland, the United States, France and Belgium.

Switzerland · Europe · US

I work just as naturally with leadership as with field teams and specialist suppliers. My role is to turn their constraints into one coherent system.

— Billy Vuilleumier

Independent, hands-on, accountable

Technology is most useful when it becomes invisible.

There is no preset catalogue of solutions. I favour choices that are simple to maintain, open where practical and sized for your reality — with particular attention to security, documentation and total cost.

  • Pragmatic architecture
  • Custom development
  • Hands-on delivery
  • Direct communication

Experience with healthcare institutions, legal professionals and organisations operating across Switzerland, Europe and the United States. Named references are available in conversation, with respect for confidentiality.

A project, a roadblock, an idea?

Let’s start with the problem.

A setup that has grown too complex, a dictation system to migrate, systems that do not talk, a new location to open or an idea to turn into a product: tell me the context. The first conversation is simply to see whether I am the right person to help.
