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 within this eclectic backdrop that I found my real calling: bringing architectural thinking into software. I am drawn to the whole system—not only how it is built, but how people experience it, how data moves through it, and how it continues to evolve over time. I design for humans, think in systems, and build for scale. Whether I am shaping a Kafka event flow, crafting a Flutter experience, or untangling a complex stored procedure, I enjoy taking ownership from the first idea through to a dependable result.

At PeopleStrong, that mindset has shaped my work on the ground-up modernization of a 20-year-old HRIS and Core HR platform. We are replacing a monolithic JSP/JSF application with Spring Boot 3.x microservices and Flutter, while keeping the needs of live enterprise clients at the center. From reworking legacy data structures and delivering employee-profile experiences to building reusable, server-driven forms, I have helped turn a difficult modernization effort into a more stable and adaptable platform.

The impact has been meaningful: 35%+ faster SQL response times, 70% fewer UI-related issues, and a successful Middle East rollout with 120+ features delivered under demanding timelines. I also created the K6 Performance Testing Framework from scratch—covering 100+ APIs across 30+ modules, with load scenarios up to 300 concurrent users, automated reporting, and CI/CD integration. It is work that reflects what I value most: making complex systems clearer, stronger, and ready for the people who rely on them.
