Adarsh Singh, AI automation and full-stack developer specializing in n8n, AI agents, RAG, and SaaS

Built a 24/7 AI voice receptionist for Hercules Detailing using Vapi, n8n, MCP, Google Calendar, and Google Sheets. Customers can call and speak naturally with an AI agent.

The receptionist finds and creates customers, checks availability, books appointments, looks up existing bookings, reschedules, and cancels appointments entirely by voice.

An n8n MCP server exposes seven tools backed by sub-workflows, while Google Calendar handles scheduling and a Sheets CRM logs every client and appointment action.

Built an automated competitor intelligence systemthat researches competitor websites, news, LinkedIn, and X/Twitter on a weekly schedule.

Airtable provides the competitor list, while AI research agents use Tavily, Apify, RapidAPI, and website screenshots to collect and analyse market, website, and social activity.

A report-writing agent turns the research into a styled HTML report with source links and sends it through Gmail, giving teams actionable competitive insights without manual research.

Built an end-to-end AI video content automation systemin n8n that turns long-form video transcripts into ready-to-publish short-form videos.

Gemini agents generate concepts, scripts, documentation, and dynamic video layouts. Replicate creates B-roll, HeyGen generates the avatar video, and Creatomate renders the final output before it is uploaded to Google Drive and logged with AI-written social copy.

The workflow connects n8n, Google Docs, Drive, Sheets, Gemini, OpenAI, Replicate, HeyGen, and Creatomate into one scalable content pipeline.
