Architecting Systems
Through Better Design

I thrive at the intersection of performance and scalability. With a deep foundation in the **Java ecosystem**, I focus on building systems that don't just work—they scale. My approach is rooted in clean code, design patterns, and a relentless pursuit of architectural excellence.

Currently, I'm a Full Stack Developer at Chandra Realtors, where I lead the development of high-throughput web platforms and multi-tenant systems.

I believe that software engineering is about solving real-world problems with elegant, maintainable code. Whether it's optimizing a Spring Boot microservice or architecting complex databases, I bring a methodical approach to every challenge.
