I'm Rohit Parit. I build secure, scalable products in Java & Spring Boot: REST APIs, microservices, payments, and AI-integrated systems used in production.
~/about
I'm Rohit Parit, a Java developer focused on building reliable, performant backends and the products around them.
Currently a Backend Java Developer at Debound, leading the migration of Bank of Maharashtra's legacy PHP stack to a modern Java ecosystem with REST APIs.
I specialise in Spring Boot, Spring Security & JWT, microservices, CI/CD, and DevOps. Recent work includes NainiStore, a hyperlocal marketplace running on Spring Boot & MongoDB, and ClearPack PackIQ Copilot, a RAG-powered backend for factory technicians.
Pursuing MCA at Manipal University Jaipur. Always learning, always shipping.
