About

Backend engineer with a focus on scalable distributed systems and AI-native infrastructure. Currently building at HDFC ERGO's Innovations team — a product-first setup where I own systems end-to-end, from API design through cloud deployment. On the infrastructure side: event-driven architectures processing 2M+ daily events on GCP Pub/Sub, Redis-backed low-latency services, PostgreSQL schema design and query optimization, and async batch workers at scale. I care about systems that are observable, cost-efficient, and don't break at 2am. On the AI side: I've architected production RAG pipelines with pgvector semantic retrieval, LLM orchestration layers with tool-calling, context caching strategies, and multi-agent systems running on Vertex AI / Gemini — all shipped to real users, not just prototyped. I like owning hard problems across the stack — system design decisions, performance bottlenecks, API contracts, database tuning. Less fan of ticket-takers, more of an engineer who ships with intention. Open to strong backend roles (SDE-2 / Senior) in product-first companies — distributed systems, high-throughput backends, or AI infrastructure. → TypeScript · NestJS · Node.js · Python · PostgreSQL · Redis · GCP · Pub/Sub · Vertex AI · Gemini APIs · RAG · pgvector · System Design · Distributed Systems

Software Development Engineer at HDFC ERGO General Insurance, Jul 2023 - Present · 3 yrs 2 mos, Mumbai, Maharashtra, India, Building production-grade backend systems at HDFC ERGO's Innovations team — working across distributed event-driven infrastructure, GenAI platforms, and high-scale product engineering. ▸ Designed and operate event-driven pipelines on GCP Pub/Sub processing 2M+ daily events for lifecycle automation — with DLQ, replay, and alerting for production reliability. ▸ Architected Fusion AI — an end-to-end GenAI platform powered by Gemini / Vertex AI with RAG pipelines, pgvector-based semantic retrieval, tool-calling orchestration, and context caching. Platform serves 109K+ queries across consumer apps with 1M+ users. ▸ Reduced a critical API latency by 99.2% (14,057ms → 115ms) through streaming optimization, intelligent caching, and Node.js performance tuning. ▸ Built Redis-backed dashboards, cron-driven batch workers, and WhatsApp re-engagement pipelines reactivating 3,000+ users daily. ▸ Owned full backend for motor insurance journeys (2W + 4W) across HERE App and PayZapp — quote, KYC, payment, policy issuance — reaching 10M+ combined installs. ▸ Shipped a multilingual in-app voice agent with intent classification, regex fast-paths, and structured deep-link navigation. ▸ VAPT-cleared API layer with JWT auth, field-level encryption, RBAC/ABAC, and Azure AD SSO across enterprise apps.
