Senior Java Backend Engineer — Distributed Systems · Cloud Architecture · Performance

I design and build enterprise-grade backend microservices, resilient distributed architectures, and cloud infrastructure that stays predictable under load. Currently engineering mission-critical financial platforms and identity theft monitoring systems for Experian India (via NetWeb Software), with a proven track record delivering measurable impact at KMA Technologies (30% checkout conversion boost).

I’m a Software Engineer at NetWeb Software, currently consulting for Experian India, where I engineer enterprise backend applications and microservices in the credit and financial analytics domain. My core focus spans identity theft monitoring, digital footprint management, credit bureau platforms, and high-security data-driven solutions.

I specialize in building distributed backend systems that maintain predictability, low latency, and fault tolerance under peak load. From tuning JVM garbage collectors and concurrency controls (CompletableFuture, ExecutorService) to architecting event-driven pipelines with AWS EventBridge and Amazon ECS, most of what I build starts from asking how the system fails before asking how it succeeds.

Prior to Experian, at KMA Technologies, I led the European payment gateway integration for Ellos, delivering a 30% increase in checkout conversions. Today, I combine enterprise engineering discipline with modern AI-assisted workflows (Claude, GitHub Copilot, ChatGPT Codex) to accelerate development velocity, maintain high test coverage, and ship robust, production-ready code.
