Amit S.

I’m an AI Engineer and Full-Stack Developer specialising in AI agents, LLM integrations, RAG systems, Python, and React Native. With 150+ jobs and 16,000+ hours on Upwork, I help businesses build AI-powered products, intelligent automation workflows, and mobile and web applications. I focus on turning AI concepts into practical software that integrates with existing systems, APIs, databases, and user-facing applications. AI AGENTS, LLMs & RAG DEVELOPMENT I help businesses integrate AI into their products and workflows, from intelligent assistants to retrieval-based applications and automated processes. My relevant areas include: - AI agents and tool/function calling - OpenAI API and LLM integrations - Claude and Gemini integrations - Retrieval-Augmented Generation (RAG) - Vector search and knowledge-based assistants - AI chatbots and conversational applications - Document processing, information extraction, and classification - AI workflow automation and third-party integrations - Python-based AI services and backend development FULL-STACK DEVELOPMENT I can also help build the application and backend components required to turn an AI feature into a usable product. - Python and REST API development - React.js and modern JavaScript/TypeScript - Node.js backend integrations - Database and third-party API connectivity - Authentication and application workflows - Integration of AI services into existing web applications - Debugging, performance improvements, and production support FLUTTER, REACT NATIVE & MOBILE APP DEVELOPMENT For businesses building AI-powered mobile products or extending an existing app, I bring experience across cross-platform application development. - React Native and Expo - Flutter, Flutterflow and Dart - iOS and Android applications - TypeScript and API integrations - Firebase and real-time application features - AI-powered chat and assistant experiences - Third-party SDK integrations - Existing app maintenance, debugging, and feature development - Testing, deployment, and app-store releases RELEVANT AI PROJECT EXPERIENCE My previous AI-related work includes an AI support automation agent built around Python, OpenAI, Twilio, and REST APIs; financial news and signal analysis using Python, data processing, vector databases, and LLM-based classification and extraction; and AI voice-based lead qualification workflows involving voice, telephony, and automation integrations. These types of projects demonstrate the practical side of AI development: connecting models with real business workflows rather than treating AI as an isolated feature. HOW I APPROACH PROJECTS I start by understanding the business requirement, the existing technical environment, and the outcome the application needs to deliver. From there, I recommend an appropriate architecture, identify the key integrations, and work towards a maintainable implementation. I can help with a new AI-powered product, an AI feature added to an existing application, an agent or RAG workflow, or a mobile app that needs ongoing development and technical support. If you're looking for an AI engineer who can connect AI capabilities with real applications and business systems, let's discuss your requirements and the most practical way to implement them.
