// about me

I turn complex problems into elegant solutions.

I'm a Computer Science engineer from Dr. N.G.P. Institute of Technology, Coimbatore, with a powerful foundation in Java, Data Structures, and Object-Oriented Programming. I don't just write code — I architect systems.

With 200+ DSA problems solved and real-world internship experience at Titan Company Limited, I've developed the problem-solving instincts and engineering discipline that top companies demand. My code is fast, readable, and built to scale.

Currently deepening my expertise in C++ and systems-level programming, pushing toward high-performance, resource-efficient software that operates at the edge of what's possible.
