Backend Engineer | Building scalable, reliable and operationally efficient systems | Distributed Systems, AI Tooling & DX

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. Selected work: - Helped launch an e-hailing aggregator platform ahead of schedule - Improved driver allocation systems, contributing to a 91% reduction in unfulfilled orders - Introduced H3-based caching that reduced map API costs by 70% - Designed sub-5ms driver availability lookups using Redis Lua for latency-sensitive workloads - Built a real-time ETA prediction engine using XGBoost and CatBoost with strong p99 performance at scale - Diagnosed and resolved production bottlenecks involving memory leaks, DNS resolution, and distributed connection lifecycle management - Helped restore critical ride-hailing infrastructure during a regional AWS outage by rebuilding infrastructure, reconstructing critical data flows, and recovering platform operations under constrained restoration scenarios - Built AI-powered internal tooling using vector databases and large-scale code indexing systems to improve developer workflows. 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. Winner of SIH Hackathon 2022.
