Nikhil Saini

Backend Engineer · Remote, India

> I build backends that stay quiet under load — scalable services, high-performance REST and GraphQL APIs, and system architecture that holds up when traffic doesn't behave.

> Currently SDE II at Plantix, working on microservices, cloud infrastructure, and platform performance. Before that: fintech payments, blockchain wallets, and real-time streaming backends.

> Off the clock I'm usually deep in AI/ML — RAG pipelines, agentic workflows, and the math behind generative models.

rag-lab

Browser-based RAG learning app that runs 100% locally — no server, no API keys, no data leaving the tab.

  • - Runs embeddings and generation entirely in-browser via Hugging Face Transformers.js.
  • - Visualizes the full pipeline: chunking, embeddings, retrieval, and generation in real time.
  • - Upload your own text, ask questions, and watch every retrieval step as it happens.
