Senior Software Engineer @ PubMatic \| Backend systems and GenAI applications

## About

Senior Software Engineer with 4\+ years building large\-scale, revenue\-critical backend systems in AdTech, now working on GenAI/AI platform components\. I specialize in distributed systems, high\-throughput data pipelines, and microservices \- primarily in Java and Spring Boot on GCP \- and I apply that same systems engineering rigor to production AI: LLM\-powered agent workflows, evaluation frameworks, and semantic routing built with LangChain/LangGraph\. Selected work: architected a high\-throughput ingestion pipeline \(LMAX Disruptor\) processing \~60M records in \~60 seconds; led migration of high\-volume jobs from Java to Apache Spark for horizontal scalability; designed Supply Chain Object filtering across 300B\+ daily ad impressions, cutting \~2% invalid traffic; built an ML\-assisted inventory categorization system that drove an estimated $7\-9M annual revenue lift; and built GenAI platform components \- agent orchestration, MCP\-based tooling, and LLM evaluation \- making AI systems production\-ready and measurable\. Core strengths: Java, Spring Boot, Apache Kafka, Apache Spark, microservices, REST API design, event\-driven and low\-latency architecture, distributed systems, MySQL/PostgreSQL tuning, Redis, Docker, Kubernetes, and system design\. AI: Generative AI, LLMs, LangChain, LangGraph, agent orchestration, prompt engineering, and machine learning\. Based in Pune; comfortable with hybrid and remote setups\. Always glad to talk shop about distributed systems, backend performance, and building reliable GenAI systems\.
