Hassan Ahmad U.

Top Rated Plus | $500K+ earned | 10+ years of Software Engineering experience I build production AI applications that connect LLMs with real business data, workflows, and software systems. My work includes RAG applications, AI agents, document intelligence, LLM integrations, intelligent assistants, and workflow automation. I also bring 10+ years of full-stack and backend engineering experience so that I can handle the complete PRODUCT not just the AI layer. I can design the architecture, build the Python/FastAPI backend, integrate LLMs and vector search, develop the React/Next.js interface, connect existing APIs and databases, and deploy the application on AWS. AI & LLM Engineering 🤖 * RAG applications and AI knowledge bases * AI agents and multi-agent workflows * LangChain and LangGraph * OpenAI and other LLM API integrations * Prompt engineering and structured outputs * Function calling and tool use * AI chatbots and intelligent assistants * Document intelligence and information extraction * Semantic search and knowledge retrieval * AI-powered workflow automation * LLM integration into existing SaaS products * Custom AI features for business applications 🔎 RAG & Knowledge Systems * Retrieval-Augmented Generation (RAG) * Document ingestion and processing * Embeddings and semantic search * Vector databases * Pinecone * PostgreSQL / pgvector * Knowledge bases * Private-data question answering * Context retrieval and ranking * Source-aware AI responses 🐍 AI Backend & APIs * Python * FastAPI * Flask * REST APIs * Async processing * Background workers * Third-party API integrations * Authentication and authorization * PostgreSQL * MySQL * MongoDB 💻 Full-Stack Engineering * React * Next.js * Node.js * TypeScript * JavaScript * ASP.NET Core * Laravel * SaaS applications * Admin dashboards * CRM and business applications ☁️ Cloud & Deployment * AWS EC2 * AWS S3 * AWS RDS * AWS Lambda * Docker * CI/CD * Production deployment * Scalable cloud architecture ## Selected AI & Software Work Pixis — AI-driven campaign management and automation platform Worked on large-scale systems involving AI-powered campaign management, automation, APIs, and enterprise workflows. RAGAdvise — AI/RAG SaaS platform Built the multi-tenant SaaS architecture around AI-powered knowledge retrieval and business workflows, including backend, APIs, database architecture, and application infrastructure. Amazify.ai — AI and ecommerce automation Worked on AI-powered ecommerce workflows and integrations connecting intelligent automation with business and marketplace data. I also have extensive experience building SaaS platforms, API integrations, data pipelines, dashboards, and automation systems, which is especially useful when an AI project needs to integrate with an existing product rather than operate as an isolated prototype. What I Can Build: * AI customer support assistants * Internal company knowledge assistants * RAG chatbots over private documents * AI document processing systems * AI email assistants * AI-powered SaaS features * Autonomous and semi-autonomous AI agents * Multi-agent workflow systems * AI workflow automation * LLM-powered search * AI CRM assistants * AI reporting and analytics * Custom OpenAI/LLM integrations * AI features for existing web applications My approach is straightforward: understand the business workflow first, design the AI architecture around the actual requirement, build the application around reliable APIs and data, and then deploy and optimize it for production. If you already have an AI prototype, an existing SaaS product that needs AI capabilities, or a business process you want to automate, send me the details. I can review the requirements and suggest a practical architecture and implementation approach. Let's discuss the project on a quick call.
