About Me
I design for clarity, efficiency, and long-term growth.

I am an IT professional with experience in web development, system infrastructure, and quantitative market analysis.

My work focuses on building structured digital environments — systems that are stable, secure, and scalable. I believe technology should reduce friction, improve workflows, and connect people meaningfully.

With a background in Informatics Engineering and hands-on experience in server management, WordPress, headless architecture, and quantitative modeling, I approach problems both technically and analytically.

I value clarity, discipline, and long-term sustainability in every system I build.
