Automate what is worth automating

Zust Systems helps SMEs in French-speaking Switzerland automate their processes: information retyped from one tool into another, documents to track down, incoming requests to sort, reports to prepare.

The firm starts from the way you already work, to find where automation brings a concrete gain. Depending on the need, the answer may be a connection between your existing tools, custom development, or a process that relies on artificial intelligence.

Understand before building

Every project begins with an examination of the process, of the time it takes and of the errors it can cause. The expected gain is estimated before any development starts.

If automation is not justified, the diagnostic says so and explains why.

Start from your tools

Your existing tools stay in place. The aim is to simplify your work while keeping the required changes to a minimum.

Scope, deliverables and exclusions are set out in the quote. Licence, API and hosting costs are estimated separately from fees.

Deliver a system you can use day to day

Delivery covers going live in your environment, the checks agreed in advance, the documentation, and the means to monitor that the system is running properly.

You know how to use it, how to spot a problem, and how to arrange its maintenance.

Leave you in control

Each automation is built so that you can keep developing it with the provider of your choice.

  • Your accounts and your environments.

    Solutions run in environments you control. Subscriptions to third-party services are taken out in your name wherever possible.

  • Your code and your documentation.

    Both are delivered into your own repository as the project goes on, and remain accessible to you.

  • Mainstream technologies.

    Standard tools and documented interfaces keep maintenance simple and let another provider take over.

Jonathan Züst, founder

Based in Morges, I work where business operations, data and software development meet.

My background in actuarial science, together with my experience in audit and banking operations, taught me to read a process, assess its risks and put figures on the improvements available.

With Zust Systems, I put that experience to work for SMEs: understanding what actually happens on the ground, identifying the tasks that can be simplified, and building solutions sized for the company and its means.

Five years in process automation, four in data science

I build and maintain automation, data processing and reporting tools, mainly in Python, SQL, Automation Anywhere, Power Automate and on Azure services. That work includes:

Banking automation

At Banque Pictet, as an external consultant, I developed and maintained reconciliation robots for trade and cash operations. I also worked on document processing and on e-mail classification using supervised learning, and contributed to the redesign of risk report generation during a major software migration.

Automation Anywhere, Python, SQL, Docker.

Business application for Cridec SA

For several years I deployed and developed MyCridec, the reporting platform Cridec SA provides to its clients and staff: dashboards, dynamic statistics and automation of the ordering process.

JavaScript, PHP, Oracle, MySQL.

These projects taught me to account for what happens after delivery: monitoring the runs, understanding the failures, and letting someone else pick the work up. Internal audit leaves you with habits: knowing what came in, what was done with it, when, and by what. In banking, nothing reaches production without tests, documentation and monitoring. The standard does not change; only the scale does.
