You're building something with AI, an agent, a SaaS product, a voice bot, or an automation system. You need it shipped correctly, not just "working." I'm Kundan, an AI engineer with 10+ years of software development experience. I've delivered 200+ digital products across 50+ industries from AI agents and RAG systems to SaaS MVPs and mobile apps. What I actually build: → AI Agents (LangChain, LangGraph, CrewAI, AutoGen, OpenAI Assistants) → Voice AI Systems (VAPI, Bland.ai, ElevenLabs, Twilio) → RAG pipelines (Pinecone, Qdrant, Weaviate, pgvector) → SaaS MVPs (Next.js 14, Supabase, Stripe, Vercel, shipped in 45 days) → React / React Native apps (production-grade, TypeScript, tested) → Python backends (FastAPI, Django, LangChain integrations) → AI Chatbots (custom trained, multi-channel, CRM integrated) What makes this different: I don't hand you a demo and disappear. Every project includes architecture design, clean handover documentation, and 30 days of post-launch support. I personally handle every discovery call and solution design, you always talk to the engineer, not a PM. One recent example: Built a production AI chatbot platform (Aionsoft) now serving businesses across multiple industries, with a full backoffice for training, analytics, and bot management.
