Full Stack Developer

// about me
Developer. Problem solver. Always learning.
I'm a Systems Engineering graduate with over a year of hands-on experience in web development. My focus is on backend architecture, but I'm equally comfortable working on the frontend.
Driven by a deep curiosity for how systems work — from web apps to ethical hacking. I love finding elegant, efficient solutions to complex problems.
Currently freelancing and open to exciting opportunities where I can grow and contribute meaningfully.
