Software Engineer | Building AI Systems, Distributed Systems & Scalable Backend Infrastructure

About

Hi, I'm Dhruv. I build AI systems that enterprises can actually trust. At South Guild Tech, I'm one of the core engineers behind an AI analytics platform that turns plain-English questions into reliable, SQL-backed answers. I've architected the agent pipeline at its heart — LangGraph-powered ReAct agents that reason over enterprise data, clarify ambiguity with humans in the loop, validate their own SQL, and stream answers in real time. Underneath it, I've built the retrieval layer that grounds every response in verified data models, and the correctness engine that blocks silent data errors — bad joins, broken grains, misleading aggregations — before they ever reach a user. That last part is what drives me. Anyone can wire up an LLM demo in a weekend. Making it production-grade — observable, guarded, honest about what it knows — is the real engineering problem, and it's the one I've chosen to work on. Before this, I built LLM-powered search and reranking at DeltaX and scaled backend services at Ninjacart. B.Tech from IIT Kanpur, class of 2023. Always happy to trade notes with people building in the LLM and data infrastructure space — dhruv.singhal2612@gmail.com Python · LangGraph · RAG · LLM Agents · FastAPI · Docker · SQL · OpenTelemetry · Spring Boot
