About

Who I am

I am a Backend Software Engineer currently pursuing my B.Tech in Computer Science Engineering at PDEU. My focus is on architecting robust systems, optimizing data pipelines, and building scalable APIs that drive real business value.

I believe in learning by doing. My journey involves diving deep into system architecture, breaking things, and building them better from scratch. Whether it's crafting high-performance backend architectures or integrating AI-driven automation workflows, I prioritize writing clean, efficient, and maintainable code.

Currently, I am working as a Freelance Software Engineer at Code O logic, where I develop scalable backend microservices and integrate AI workflows. I also serve as a Tech Core Member at GeekForGeeks PDEU, mentoring peers in Data Structures and Algorithms.
