About

I build backend systems that scale — and I do it with deep engineering conviction. With 12+ years of experience, I specialise in Java-based backend development, concurrent system design, and microservice architectures. At Ericsson, I've shipped production-grade telecom software — from event-driven pipelines using Kafka Connect and Google Pub/Sub, to containerised deployments with zero-downtime rolling upgrades on Kubernetes. What sets me apart is a systems-first mindset forged early in my career, when I architected a real-time railway simulation engine from scratch — building a 9-tile infinite terrain streaming system, GPU-accelerated HLSL shader rendering, and custom binary file formats optimised for O(1) random-access reads. That experience gave me a rare instinct for memory efficiency, latency reduction, and resource optimisation that most backend engineers don't develop. What I bring: • Deep Java expertise: multithreading, executor framework, concurrent collections, JVM performance • Proven backend systems: microservices, Kafka Connect, REST APIs, Spring Boot • Cloud-native delivery: Docker, Kubernetes, CI/CD automation • Automation wins: reduced release documentation time from ~1 day to ~5 minutes • 3x Best Performer at Ericsson — I don't just ship, I lead I also author the newsletter "Level Up Your Programming with Nitin" covering Java, DSA, and system design. Actively exploring Senior / Staff Engineer opportunities where backend depth and systems thinking are valued.
