Saurabh S.

Senior Full-Stack Developer | React, React Native

I'm a full-stack engineer — 10+ years building web and mobile apps, the last two building AI into them. Chatbots that answer from your own documents. Assistants that do real work instead of demos. Features that hold up when actual users touch them. AI WORK I'VE SHIPPED 🔷 Remindful — AI caregiver assistant. LLM integration, conversational flows, production reliability. Ongoing. 🔷 Full-stack GenAI development for a cybersecurity platform (ReactJS + generative AI features) 🔷 Front-end rebuild of an AI platform 🔷 Reliability audit of an AI agent orchestration tool — JSON schema validation (React / Next.js) AI CAPABILITIES 🔷 LLM integration — OpenAI, Anthropic Claude, streaming, function calling, tool use 🔷 RAG — chunking, embeddings, vector search, retrieval tuning 🔷 Vector databases — pgvector, Pinecone, Supabase vector 🔷 AI agents — multi-agent orchestration, MCP server integration 🔷 Prompt engineering, evals, observability, cost optimisation 🔷 AI chatbots and workflow automation AI-GENERATED CODE I use AI heavily in my own work — but I drive it, I don't follow it. I know where LLM-generated code breaks: silent type errors, unhandled edge cases, architecture that doesn't survive the second feature. Built something with Cursor or Claude Code that stalled? I'll audit it and get it to production.
