Aaroh Bhardwaj

I’m a backend-focused engineer building reliable, low-latency systems and scalable APIs, with a strong emphasis on correctness, observability, and performance. As a Full Stack Developer Intern, I built and optimized NestJS backends—adding validation layers, guards, caching, and efficient query patterns—to improve API latency and stability.

I’ve also delivered production-grade event-driven and RAG systems: Invar uses Redis Streams with consumer groups to support 1K+ events/min and near-zero backlog via idempotent processing, retries, and DLQs, while SentinelRAG builds hybrid retrieval (BM25 + embeddings) with LLM reranking for sub-1s retrieval and low end-to-end latency. I design stage-wise observability, structured logging, and decoupled services, and I deploy containerized workloads on GCP Cloud Run with CI/CD via Cloud Build.
