Software Engineer 2 @ Dell Technologies

Hi, I'm Rohit Jarariya — full-stack engineer · distributed systems & GenAI

I design and build systems that scale, end to end.

From system design and distributed backends in Java, Spring Boot, Kafka and Redis to GenAI features with RAG & LangChain and React/Next.js frontends — grounded in strong data structures & algorithms.

01About

A bit about me

I'm a full-stack software engineer at Dell Technologies, where I've been building since joining as a Graduate Intern in 2022. I enjoy owning problems end to end — from system design and APIs to data pipelines and the UI on top.

On the backend I design distributed systems in Java and Spring Boot with Kafka, Redis, Neo4j and PostgreSQL: a cross-service data lineage engine, a distributed rate limiter & API gateway, and a fault-tolerant workflow engine. I also build GenAI features — RAG pipelines and LLM-powered interfaces with LangChain, Spring AI and Ollama — and frontends with React, Next.js and TypeScript.

My foundation is strong CS fundamentals — data structures & algorithms, system design, computer networks and databases — sharpened through an MTech in Computer Science (Computer Networking) at NIT Bhopal and regular problem solving on LeetCode.

CODELINE

Cross-Service Data Lineage Engine

A distributed platform that auto-discovers how data flows across Spring Boot microservices, builds a lineage graph, and answers impact, compliance and “where does this field go?” questions.

Atomic rate limiting across gateway instances with Redis Lua

Why a read-then-write rate limiter breaks as soon as you run two gateways, and how SENTINEL makes the token bucket check atomic with a single Redis Lua script.

    Efficient Health Information Exchange Automation System based on Blockchain and IPFS

    Rohit Kumar Jarariya, Sri Khetwat Saritha, Sweta Jain

    Blockchain in Healthcare Today · Vol. 8, No. 3

    A decentralized health information exchange in which patients control who can see their records. Medical data is stored on IPFS for scalable, content-addressed storage, while Ethereum smart contracts enforce access control — evaluated on Ethereum for transaction cost and accuracy.
