AN ARCHITECT & DESIGNER BY PASSION, ENGINEERED INTO A SOFTWARE DEVELOPER.

I'm a Senior Software Engineer with over 4 years of experience bringing a unique perspective to the tech landscape. With hands-on expertise across HR Tech, Finance, and SAP domains, I specialize in taking legacy systems and transforming them into modern, high-performance platforms.

My journey began with a Bachelor's degree in Architecture from Amity University, Mumbai — rooted in the principles of design, innovation, and creative problem-solving. Venturing beyond architecture, I explored multifaceted roles that enriched my skill set: from orchestrating HR strategies as an Associate to crafting captivating visual narratives as a Graphic Designer in the vibrant landscape of the United States.

It was amidst this eclectic backdrop that my true calling emerged — a fervent desire to merge my architectural ingenuity with the dynamic realm of software development. I think in systems, design for humans, and build for scale. Whether it's a Kafka event pipeline, a Flutter UI, or a complex stored procedure — I own it end-to-end.

At PeopleStrong, I'm leading the ground-up modernization of their HRIS & Core HR platform — replacing a monolithic JSP/JSF system with Spring Boot 3.x microservices + Flutter. The results: 35%+ faster SQL response times, 70% fewer UI issues, and a direct 20% revenue increase — delivered in just 6 months with live enterprise clients.

I also conceptualized and built the entire K6 Performance Testing Framework from scratch — covering 100+ APIs across 30+ modules with load profiles up to 300 concurrent users, automated reporting, and CI/CD integration.
