Prakhar Nagpal

I architect secure platforms, engineer high-throughput APIs, and ship AI-driven products that turn complex systems into fast, reliable user experiences.

About

Engineering depth with a product-maker's eye.

I like systems that are measurable, resilient, and pleasant to use.

I am a Master of Computing student at the National University of Singapore, specializing in computer science and building at the intersection of scalable systems, applied AI, and product engineering.

I have architected secure login flows for 80K+ users, engineered .NET REST APIs handling 1M+ daily hits, and shipped mobile-first finance workflows that supported 50K+ peak daily active users.

My work tends to sit where reliability meets velocity: translating complex business rules into clean systems, improving performance under real traffic, and turning research-grade ideas into shippable software.
