Most developers hand you a working demo. I hand you a working product. I am Rakesh, a Full-Stack and AI Engineer with 3+ years of experience taking projects from idea to deployment web, mobile, and AI systems included. Whether you need an intelligent chatbot, a production LLM pipeline, or a full SaaS platform, I handle the entire lifecycle without you needing to coordinate between multiple people. On the AI side, I build AI voice receptionist, AI automated pipelines , RAG systems, document-aware assistants, agentic workflows, and LLM integrations using OpenAI, Gemini, LangChain, and LangGraph, Langfuse with proper evaluation, tracing, and production deployment, not just a prototype that breaks under real usage. On the product side, I build scalable web applications with Next.js, React, and Supabase, and cross-platform mobile apps with Flutter and React Native both Android and iOS, ready for real users. I have delivered healthcare platforms, financial tools, tourism apps, and AI-powered support systems all live, all in production. You can see them in my portfolio. What clients consistently say about working with me: clear communication, reliable updates, and code that does not need to be rewritten three months later. I am open to signing an IP agreement from Day 1 - your code, your server, your database, everything stays yours. Feel free to invite me or send a message Thanks
