Technology · Systems and automation

I build internal systems, automations and integrations that take operations off spreadsheets and manual work.

I started by automating logistics in Excel/VBA. Today I build web applications, integrations and AI tools, from requirements to a system in use.

When to call me

Information is scattered across spreadsheets and systems that don’t talk to each other.
Someone spends hours copying data from one place to another.
You need an internal tool that doesn’t exist off the shelf.
The team wants to use AI at work and doesn’t know where to start.

I build registrations, approval workflows, dashboards and planning tools tailored to the operation.

I connect the systems you already use and automate the tasks that are copied by hand today.

I build assistants, document reading and agents for specific tasks, with a person reviewing the result.

I train teams to use AI in their own work, with exercises on their own tasks and care for their data.

When it goes further

When it’s not yet clear what the system needs to do, I start with process analysis. When the team doesn’t adopt the tool, I work on the conversation.
