Some might say I fell in love with Angelina Jolie back in '98, but it was actually programming that got me hooked while watching "Hackers." Since then, I started coding and never stopped. 

I have worked on various projects since the beginning of my programming career, but I always wanted to do something big. So, I decided to form the Tridesetri team, and we created extraordinary platforms, including the Serpence SEO tool. Working on Serpence only intensified my already strong passion for technical SEO. As the true programmer I am, I always ensure that a project's technical details are fully optimized.   

I'm eager to share my knowledge and make technical SEO easy and accessible to beginners as well.
