(About Me)

I’m a Computer Science Engineering student who enjoys turning ideas into real, working projects. I’m particularly interested in software development, Android, web technologies, backend systems, AI, and cloud computing.

I believe the best way to learn technology is by building. Over time, I’ve worked on different projects, explored new technologies, participated in hackathons and competitions, and continuously practiced DSA and problem-solving through LeetCode.

I enjoy taking an idea from a simple concept to a complete solution—figuring out the logic, building the application, improving the user experience, and solving problems along the way.

I’m still learning and growing every day, but my goal is clear: to become a skilled software engineer who builds useful, reliable, and impactful technology.
