I’m a backend engineer with around 3 years of experience designing and scaling distributed systems, with a core strength in Java and Spring Boot. Most recently I built fintech services at LXME, where I delivered REST APIs powering investments and personal finance with a strong focus on correctness and security. Before that, at Truliacare (formerly Kratin), I migrated messaging infrastructure to Azure Event Hub, architected systems handling over a billion events annually, and built reusable libraries to streamline development. Today I’m a Software Engineer at CarWale, building backend services and REST APIs on the .NET stack for India’s leading automotive marketplace — applying the same service design, performance, and testing discipline I built on the JVM. Earlier at Hitachi Vantara, I strengthened database performance through optimized SQL queries and delivered robust REST APIs. My passion lies in solving distributed systems challenges and automating workflows to drive efficiency.

Server-side rendering isn't a performance flex — it's a traffic strategy. A visual walkthrough of how SSR gets your pages into Google's index, why B2C companies live and die by it, and when it's actually worth the cost.
From Java Spring Boot to .NET: What Actually Transfers
I spent years writing Java and Spring Boot, then joined CarWale and started shipping C# and .NET. Here's what carried over cleanly, what I had to relearn, and why the mental model matters more than the syntax.
What Building Fintech Taught Me About Correctness
Six months as a Java/Spring Boot engineer on a fintech platform rewired how I think about money, idempotency, and bugs that cost real rupees. Notes from LXME on why correctness beats cleverness.
