Backend Engineer \| Building Real\-Time & Event\-Driven Systems \| Node\.js, Redis, WebSockets

## About

Backend engineer working on real\-time, event\-driven systems with a focus on performance, scalability, and reliability\. I have 3\+ years of experience building and operating backend services using Node\.js, Redis, WebSockets, and SQL/NoSQL databases\. My work includes designing async job pipelines, optimizing low\-latency real\-time systems, and supporting production systems handling concurrent workloads\. At Idea Usher, I’ve worked on optimizing WebSocket\-based architectures, reducing end\-to\-end latency by an order of magnitude, building Redis\-backed async pipelines, and owning CI/CD workflows to improve release stability\. Outside of work, I actively build system\-level backend projects such as real\-time trading engines, distributed job processors, and event\-driven services\. I enjoy reasoning about system design trade\-offs, failure handling, and performance bottlenecks\. Currently exploring backend roles at product\-focused teams where I can work on high\-impact systems at scale\.
