About Me

Hi! I'm Mahir. For most of my university life, I was confused about what I actually wanted to do. I tried a bit of everything. Animation, design, web development, but none of them truly felt exciting to me.

That changed when I was introduced to SQL in one of my courses. I got hooked almost instantly, and that’s when I started enjoying the idea of working with data. What began as curiosity slowly turned into a career. I started with a freelance gig for an f-commerce business, and right after graduation, I landed my first corporate role as a Data Analyst at one of the leading insurance companies in my country.

Outside of data, I’m also into design, marketing and gaming. And I'm still figuring things out, still learning and always happy to connect with good people along the way.
