About

Software Engineer with 2+ years of experience across backend development, infrastructure, and distributed systems currently focused on backend engineering and scalable API design. Previously at Qure.ai (Series C AI healthcare, 50+ hospitals globally) as a DevOps & Infrastructure Engineer, where I owned production Linux environments, Docker deployments, AWS/Azure cloud infrastructure, CI/CD pipelines, and monitoring with Datadog supporting backend services at scale in a regulated healthcare environment. Since then, I've been deliberately building backend engineering depth through freelance client work and personal projects: → Distributed Rate Limiter — Token Bucket + Sliding Window algorithms, microservice architecture, ~47 req/s throughput, p95 latency under 100ms (Node.js, Redis, Docker, k6) → DevPath — Full-stack MERN platform with Redis-powered recommendation engine, JWT auth, 45% API latency reduction via MongoDB optimisation → SocialPulse — Real-time analytics backend processing high-volume social data streams, sub-50ms response times (FastAPI, Node.js, MongoDB, Redis) Core skills: Node.js · Express.js · MongoDB · Redis · AWS · Docker · Python · Linux · Ansible · Data structure and Algorithms · Datadog · System Design · CI/CD I bring something most backend engineers don't , I've lived on both sides of the deployment boundary. I know how my code behaves in production because I've been the one keeping that production running. 📩 Reach me at: cashwin2002@gmail.com
