Arun K.

AI Developer and AI Agent engineer, Top Rated Plus with $400K+ earned and 19,000+ hours on Upwork. I build AI agents that take real work off your team: voice AI receptionists, RAG knowledge assistants, custom MCP servers and LLM automations connected to your CRM. IIT Delhi computer science graduate with 10+ years of engineering experience.

HOW I WORK
We start with a short scoping call to agree on the exact task the agent owns, the data and tools it can use, and how we measure success. You get a working prototype early, weekly demos, and a production release with logging, guardrails and handover notes so your team can run it.

RECENT AI PROJECTS

• SMS AI ordering platform: customers order by text message with RAG product search, OpenAI replies and Twilio. 5.0 client rating.
• AI-built app to production: took a Base44 prototype, fixed the bugs, finished the features and shipped it live.
• Leadzilla: AI lead generation and AI email-writing web app.

WHAT I BUILD
AI agents: sales, support and research agents; multi-agent systems with LangGraph, LangChain, CrewAI and AutoGen; human approval steps where they matter.
Voice AI: inbound and outbound call agents and AI receptionists on Vapi, Retell AI, ElevenLabs, Deepgram and Twilio that book appointments and update your CRM.
LLM, RAG and MCP: retrieval over your documents with vector databases, tool calling, custom MCP servers, and OpenAI, Claude and Gemini integrations.
AI automation: n8n, Make, Zapier and Power Automate workflows with AI steps, connected to Salesforce, HubSpot, GoHighLevel, Zoho and your own APIs.
AI apps: AI SaaS products and AI-built app rescues (Lovable, Bolt, Base44, Cursor) taken to production.
