About Me

Process Automation Advisor

Do you spend hours every week doing the same tasks on your computer — copying data from one place to another, building reports by hand, answering the same questions over and over, tracking spreadsheets that are never up to date? All that time could be going toward what truly matters in your business.

That is exactly the problem I solve. With over 20 years of experience in industrial processes and data analysis, I now dedicate my work to helping businesses and professionals stop wasting time on repetitive tasks. I identify what can be reorganized, simplify what is unnecessarily complex, and then automate — using AI tools or not, depending on what makes the most sense for each situation.

I use n8n as my primary automation platform: a visual tool that connects systems, triggers automatic actions, and delivers results fast — without months of development. The deliverable is concrete: less manual work, fewer errors, and more free time for you to focus on what generates real value.

The Method

Before automating anything, you need to understand what is actually happening. The RSA Method — Reorganize, Simplify, and Automate follows a simple and effective logic: first we tidy the house, then we remove what is unnecessary, and only then we put technology to work for you.

The result? Processes that used to depend on someone doing everything manually now run on their own — consistently, without errors, and without consuming your day. Whether with AI, simple flow automations, or system integrations, the focus is always the same: deliver real, measurable gains for your business.

For those who believe that learning by doing is the only true way to learn. Practical STEAM projects — for the curious, educators, and creators who want to do more than consume content.

I write periodically on this Substack about educational and technical projects.
