# Aniket Kumar Sinha - Full Profile ## About Backend engineer focused on building scalable distributed systems that improve reliability, operational efficiency, and real-world business outcomes. I work across backend architecture, infrastructure, performance engineering, and AI-powered developer tooling, primarily using Node.js, NestJS, Fastify, Kafka, Redis, MongoDB, and AWS. At Zed Mobility, I have contributed across backend systems, infrastructure, and platform reliability initiatives powering large-scale mobility workloads. My work has focused on improving allocation efficiency, reducing operational costs, strengthening system resilience, and enabling faster execution across engineering teams. I enjoy solving engineering problems that sit at the intersection of scale, reliability, developer productivity, and business impact. My work often involves driving cross-functional execution across backend systems, infrastructure, observability, and operational resilience. Outside of work, I contribute to open source, including adding grouped rate limiting and exponential backoff support to Fastify Rate Limit. I also actively explore AI-native engineering workflows, retrieval systems, and large-scale code understanding systems.
