My journey into software development did not begin with a formal plan. It began with curiosity. I have always been fascinated by how things work, and when I discovered programming, I realized I had found a medium where ideas could be transformed into tools, platforms, and experiences that solve real problems. That sense of possibility has stayed with me ever since.
I have designed scalable, performance-driven applications across various domains, from optimizing logistics networks to improving healthcare systems.
However, I believe great software is more than just great code. It is about understanding people. It is about empathy.
