About Sergio

I help businesses automate repetitive tasks and optimize their IT systems to save time, reduce errors, and improve efficiency.

With over 20 years of experience in IT, I specialize in designing and implementing workflow automation solutions using tools like Power Automate, as well as managing and improving overall IT infrastructure.

I work with small and medium-sized businesses, offices, and professional environments (such as legal and administrative teams) to streamline document management, automate file handling, and simplify daily operations. From organizing digital workspaces to building automated processes, I focus on practical solutions that deliver immediate value.

My background includes system administration (Windows, Linux, Unix), network management, security, backups, and advanced technical support. I have also developed custom solutions and internal tools using technologies such as PowerShell, Python, SQL, and web technologies to optimize business processes.

What sets me apart is my ability to combine deep technical expertise with a clear understanding of business needs. I don’t just fix problems — I design reliable, scalable solutions that improve the way you work.

Typical projects I handle include:

Automating document workflows and file management
Implementing Power Automate solutions for daily tasks
Organizing and optimizing digital environments (OneDrive, Google Drive, local systems)
IT system setup, maintenance, and troubleshooting
Process optimization for offices and small businesses

I deliver solutions that are practical, efficient, and easy to maintain — helping you focus on your core business while technology works for you.
