Advait Nandeshwar — Software Engineer

01 / ABOUT

Engineering systems that scale.

I'm a software engineer based in Pune, Maharashtra, India, and a Toptal Top 3% Verified Expert in Engineering. I focus on orchestrating robust systems architecture and complex enterprise integrations at scale — transforming legacy monoliths into highly decoupled, event-driven microservices that ensure exceptional fault tolerance and minimized latency.

I combine hands-on architectural design with strategic team leadership to engineer stateless, high-performance distributed backends and scalable infrastructure that support expansive growth — whether that means leading engineering teams, integrating payment and logistics platforms, or building headless commerce experiences.

Beyond enterprise architecture, I've personally shipped 40+ production websites and platforms for clients across cannabis, health & wellness, real estate, fintech, and education — giving me a rare mix of deep systems architecture and fast, reliable client delivery.
