## 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
