I build RAG pipelines, AI chatbots, and AI agents with LangChain, OpenAI, Claude, and Gemini — 126 Upwork jobs, $600K+ earned, and 9,000+ hours delivering production AI systems, not prototypes. Recent work includes an AI appointment chatbot built over 3,200 hours (5.0★), an AI storybook platform (GPT-4o, Supabase, Stripe — 1,315 hours, 5.0★), a custom-trained coaching assistant, a health-insurance query chatbot, and a multi-agent system delivered under a contract literally titled "Chatbot langchain agents." 🔹 What I build ● RAG & knowledge assistants — vector search over your documents (Pinecone, FAISS, Weaviate), hybrid retrieval, re-ranking, and hallucination control, so the bot answers from YOUR data ● AI chatbots — multi-turn memory, session state, website/CRM integration, support deflection ● AI agents & multi-agent systems — task planning, tool use, function calling, workflow automation ● Document AI — OCR pipelines, PDF extraction, NER, classification, handwriting recognition ● LLM apps end to end — FastAPI backends, model routing, cost and latency tuning, evaluation 🔹 Results you can verify in my work history ● AI appointment & booking chatbot — 3,200 hours over 14 months, 5.0★: "a great team that will be able to build your projects from scratch" ● Handwriting-OCR digitization of paper forms — 5.0★: "very successful implementation… going to save us hundreds of hours of work" ● AI storybook web platform (GPT-4o, Supabase, Stripe) — 1,315 hours, 5.0★: "delivers high quality work, communicates clearly, and follows through" ● Custom-trained coaching assistant for an online course — 5.0★: "committed to completing the project you envision" ● Voice & call AI — golf-caddy voice agent ("I would highly recommend working with Anurag"), GPT call-review system, sales-call feedback tool ● Support & domain chatbots — health-insurance queries, customer support ("seamless from start to finish"), interior-design website ("delivered tremendous strong work") 🔹 How I work Milestones on every fixed-price project, clear written updates, and working software demoed weekly. First reply within the hour during IST work hours; risks flagged early, never at delivery. 🔹 Stack LangChain, LlamaIndex, OpenAI (GPT-4o family), Anthropic Claude, Google Gemini, LLaMA/Mistral, Pinecone, FAISS, Weaviate, Python, FastAPI, Node.js, PostgreSQL, Docker, Kubernetes, AWS, GCP, Azure. Backed by Hestabit — an ISO 27001 and SOC 2 Type II certified team — for projects that need NDAs, security review, or extra hands. If you need a chatbot that answers from your own data, an agent that automates a real workflow, or an LLM feature shipped inside your product, send me the job details — I'll reply with a concrete plan, timeline, and cost.

I build production-grade mobile applications for iOS and Android with a strong focus on performance, clean architecture, and long-term scalability. With 12+ years of experience, I specialize in complex mobile systems, including React Native with custom native modules, BLE/IoT integrations, hardware-connected apps, and high-performance media applications. I work comfortably across both native (Swift, Kotlin) and cross-platform stacks, allowing me to solve problems that require bridging beyond standard SDK limitations. Alongside this, I actively work on integrating AI-powered capabilities into mobile apps to enhance real user experiences. This includes: • AI assistants & chat features using OpenAI (GPT) and Claude • Voice-based interactions using Whisper, Google Speech-to-Text, and ElevenLabs (speech-to-text and text-to-speech) • On-device AI using Core ML, TensorFlow Lite, and ML Kit for faster and privacy-focused processing • AI-driven data handling using tools like LangChain and vector databases (for search, memory, and structured responses) • Image & media processing using Vision APIs and OpenCV-based solutions I have successfully delivered and launched apps across healthcare, IoT, booking platforms, social applications, and hardware-integrated solutions, handling everything from architecture design to App Store / Play Store deployment. I focus on building robust applications that are technically sound, user-friendly, and ready for long-term growth. Send a message and let's get started :)
