Kuldeep Singh R.

I am an AI focused Full Stack Engineer with hands on experience building and working on AI agents and automation workflows. ▪️ Top Rated Plus on Upwork with 5,000+ hours tracked ▪️ 7+ years of full stack development experience ▪️ 4+ years working specifically with AI ▪️Built and worked on 40+ AI agents and automation workflows ▪️Experience with LLMs, AI Agents, RAG, Conversational AI, Voice AI, AI Automation, API integrations and SaaS platforms ▪️Worked across healthcare, ecommerce, finance, real estate, customer support, research and business automation ▪️Strong focus on taking AI features from an initial concept through development, integrations, testing and production 💡𝐖𝐡𝐚𝐭 𝐈 𝐔𝐬𝐮𝐚𝐥𝐥𝐲 𝐁𝐮𝐢𝐥𝐝 AI Agents & Agentic Workflows - Agents that can reason, use tools/APIs, retrieve information, maintain context and actually get things done instead of just having impressive conversations. RAG & Knowledge Systems - Private knowledge bases with retrieval, embeddings, semantic/hybrid search, citations and evaluation. Voice AI - AI voice agents with speech to text, LLM reasoning, tool calling, business integrations, call handling and human handoff. AI Automation - Connecting AI with CRMs, APIs, databases, ecommerce platforms and tools like n8n/Make to remove repetitive manual work. AI SaaS & Copilots - Taking an AI idea from “this could be cool” to an actual product people can use. AI + Existing Software - If you already have a working product, I don't immediately suggest rebuilding the whole universe. I can work with the existing backend, APIs and database and add the AI layer where it actually makes sense. ✅𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤 ▪️AI: OpenAI • Anthropic Claude • LangChain • LangGraph • RAG • AI Agents • Embeddings ▪️Backend: Python • Node.js • REST APIs • Webhooks ▪️Frontend: React • Next.js • TypeScript ▪️Database: PostgreSQL • Supabase • MongoDB ▪️Automation: n8n • Make • API Integrations ▪️Cloud: AWS • Azure • Vercel • Docker ✅𝐌𝐲 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐀𝐩𝐩𝐫𝐨𝐚𝐜𝐡 I focus on building AI systems that are reliable, maintainable and production-ready, rather than simply adding an LLM to an application. I separate deterministic business logic from AI-driven decisions, use structured outputs and validation, introduce human approval where needed, and include logging and evaluation so the system can be monitored and improved over time. Whether you already have an application and want to add AI or you are starting with an idea, I can help with the architecture, development, integrations and production implementation. Let's build something useful with AI, not just something that uses AI. #AI #AIAgents #AIAutomation #GenerativeAI #RAG #VoiceAI #LLM #FullStackDevelopment #SaaS #OpenAI #Claude #LangChain #LangGraph #n8n My expertise spans both frontend and backend technologies, as well as a variety of tools and additional skills that enable me to deliver comprehensive solutions.
