<About />

Building reliable systems and automating everything possible

I'm a Systems Administrator and Automation Architect with deep expertise in Linux infrastructure, containerization, and no-code automation.

My journey spans from configuring bare-metal servers to orchestrating complex n8n workflows that save businesses hundreds of hours monthly.

Currently focused on IT infrastructure auditing, marketing automation deployment, and creating TikTok tech content that simplifies complex topics.
