// Who Am I?

I'm a System Engineer at TCS and Full-Stack & AI Developer passionate about building high-performance systems — from production-grade Retrieval-Augmented Generation (RAG) pipelines and high-concurrency microservices to native C++ desktop applications.

With a B.Tech in Computer Science from VIT Vellore, I bring deep hands-on expertise in Python, C++, Java, FastAPI, and cloud-native toolchains. At TCS, I engineer scalable cloud workflows and deployment automation that streamline enterprise release cycles.

Driven by engineering craftsmanship and continuous innovation, I thrive on solving complex technical challenges and turning ambitious ideas into reliable, high-impact software.
