Job Success
Nangal, India - 12:23 pm local time
If you need an AI agent, RAG system, LLM application, AI chatbot, document Q&A system, knowledge assistant, or AI SaaS feature, I can design and build it end to end — from architecture and AI workflow to backend, integrations, deployment, and optimization.
What I can build for you:
• AI Agents — autonomous workflows, research agents, lead qualification, data analysis, task automation, and multi-step business processes
• RAG Applications — company knowledge bases, document search, SOP/policy assistants, internal knowledge systems, and document Q&A
• LLM Applications — AI copilots, chatbots, summarization, classification, extraction, content generation, and intelligent search
• AI SaaS Products — AI-powered features, dashboards, subscriptions, user management, APIs, and scalable SaaS platforms
• AI Automation — connect AI with your existing tools, APIs, databases, CRMs, and business workflows
• Full-Stack AI Development — Next.js/React frontend, Python/FastAPI or Node.js backend, APIs, databases, Docker, AWS, and production deployment.
AI technologies I work with:
OpenAI, GPT, Claude, LangChain, LlamaIndex, CrewAI, RAG, vector databases, Pinecone, Weaviate, embeddings, AI agents, prompt engineering, function/tool calling, FastAPI, Python, Node.js, Next.js, React, Laravel, AWS, Docker and API integrations.
My approach is focused on business outcomes:
Understand your business workflow, users, data, and desired outcome
Choose the right AI architecture, model, RAG strategy, and tools
Build the AI workflow and full-stack application around your real data
Test accuracy, edge cases, performance, security, and AI costs
Deploy to production and optimize based on real user behavior
I don't treat AI as a separate feature that gets handed over at the end. I build the surrounding product so the AI is actually useful, reliable, and ready for real users.
Why clients choose me:
• $100K+ earned on Upwork
• 236 completed jobs
• 7,300+ hours worked
• 100% Job Success
• Native/Bilingual English
• 0–4 hour average response time
• Available 30+ hours/week
My core focus is AI product development — especially AI agents, RAG systems, LLM applications, AI SaaS, and AI automation.
If you already have a product idea, workflow, documents, API, or existing application, send me the goal and what you want the AI to accomplish. I'll help you choose the right approach and turn it into a production-ready solution.
Thanks,
Talwinder
