Ayush P Chaudhary

Backend Engineer

open to work

Hey there! 👋 I'm Ayush. I build backend systems that stay fast under load. I'm currently a backend engineer at Scholiphi, an AI-powered school management platform. Before that I rebuilt Homeplanr's backend as Spring Boot microservices at CPCL, cutting page load times by 80%, and was a backend engineer and prop trader at Jainam Broking (Trade Delta), writing low-latency C++ trading algorithms and breaking a monolith into Kafka-driven microservices.

I'm also a SEBI-registered Research Analyst and trade futures & options with live capital, so I think about latency, correctness and risk the way a trading desk does. I write a lot of Java, Spring Boot and C++, and I'm a regular at LeetCode contests.

Right now I'm open to backend and fintech engineering roles, so let's talk.

Every role shipped something: a faster system, a cleaner architecture or a sharper instinct for risk. HEAD is where I am now.
