Most AI features look great in a demo and fall apart the moment real users, real data, and real edge cases hit them. I build the version that survives production.
I'm Muhammad Mubeen — an AI engineer who ships agentic systems on a full-stack Next.js and NestJS foundation. I don't wire up a no-code chatbot and call it AI. I build stateful multi-agent workflows in LangGraph, RAG pipelines grounded in your own data, and voice agents that handle live calls — then deploy, monitor, and hand them off clean.
𝗪𝗛𝗔𝗧 𝗜'𝗩𝗘 𝗦𝗛𝗜𝗣𝗣𝗘𝗗
📧 EmailManager.ai — AI email productivity SaaS (NestJS + Supabase + LangChain/LangGraph + OpenAI, RAG-backed). Automated triage, drafting, and follow-ups that used to be fully manual.
🏗️ Planscan — agent-driven document processor that extracts and analyses complex construction blueprints automatically.
💼 Rilati / JobScan — full-stack career platforms with AI job matching and resume parsing, built to scale.
𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 𝗙𝗢𝗥 𝗖𝗟𝗜𝗘𝗡𝗧𝗦
🤖 Agentic AI — multi-agent LangGraph workflows, LangChain reasoning and retrieval pipelines, autonomous support and research agents.
📚 RAG systems — your documents and databases turned into grounded, cited answers, with "I don't know" instead of hallucinations.
🎙 Voice AI — Retell-based inbound/outbound call agents with CRM sync and clean human handoff.
⚙️ Automation — API integrations, webhooks, and n8n pipelines that remove repetitive manual work.
🌐 Full-stack SaaS — Next.js/NestJS apps with secure auth, dashboards, and Stripe billing. Production-ready, not prototypes.
