You will get a custom AI agent with LLM, RAG, and workflow automation
Rising Talent
Project details
I build custom AI agents and chatbot systems that connect LLMs, workflows, APIs, and your business data into practical, usable software. This project is a strong fit if you need a chatbot, RAG-based assistant, internal AI tool, workflow agent, or customer-facing AI feature.
Depending on the tier, I can help with prompt design, AI model integration, database or API connection, workflow automation, testing, deployment, and delivery documentation. My approach is focused on building reliable AI systems that are actually useful in a product or business workflow, not just basic demo outputs.
This catalog is ideal for founders, startups, and teams that want a custom AI solution built around their use case, tools, and user experience.

Full stack developer with Blockchain experience
Mr Niteen was quite professional and skilled developer. the best thing was his consultation and signing the NDA first. As a result, he pointed out that our exit approach had major performance and production issues that would have cost us time and money. Thanks to mr Niteen. He completed all of the tasks I initially requested. His expertise of the technologies was amazing. His documentation and the way he delivered the solution impressed my dev ops team a lot. Looking forward to working with him again.

Job Success
Hyderabad, India - 4:51 am local time
My strongest work includes AI agents, RAG-based chat systems, AI chatbot integration, workflow automation, CRM/API integrations, and full-stack SaaS development.
I work end-to-end across system architecture, backend logic, frontend delivery, integrations, and deployment, so clients do not need to hire separate AI, backend, and product freelancers.
My background combines software engineering, AI integration, and product execution. I work well with founders, startups, and teams that need practical implementation, not just ideas.
Core areas I help with:
• LLM integrations and AI features
• RAG systems and AI chatbots
• n8n, Make, Zapier, and API-based automation
• React, Next.js, Node.js, Express
• MongoDB, PostgreSQL, Firebase
• SaaS MVPs, internal tools, dashboards, and workflow systems
I am a strong fit for projects where AI, automation, and product development need to work together as one clean system.
I also have experience with blockchain-based product development, including smart contracts, dApps, wallet-connected systems, and Web3-related implementation when a project requires it.
On Upwork, I currently maintain 100% Job Success, with client feedback highlighting clear communication, fast understanding of requirements, and reliable delivery.
Recent Upwork work includes AI chatbot integration, founder-facing product consultation, dynamic website development, and blockchain-enabled product work.
