Project details
Most businesses lose leads because no one is available to answer at 2am. An AI chatbot trained on your business changes that.
I build custom AI chatbots using OpenAI and Claude APIs for startups, SaaS platforms, and service businesses. Whether you need a smart support assistant, a lead capture bot, or a RAG-powered knowledge base I build it clean, tested, and ready to deploy.
WHAT YOU GET
• Custom AI chatbot trained on your business data
• RAG pipeline with Qdrant vector database for accurate answers
• Embeddable chat widget for any website or platform
• OpenAI GPT or Claude (Anthropic) model integration
• Conversation memory and context management
• CRM and WhatsApp API integration
• MCP server architecture for advanced agentic workflows
• Full source code with deployment and documentation
TECH STACK

Backend: Node.js, Express.js, PHP, Laravel

Job Success
Dubai, United Arab Emirates - 3:07 pm local time
I have 7 years of full-stack development experience working with Node.js, TypeScript, React, Next.js, Laravel, PHP, PostgreSQL, MySQL, MongoDB, Redis, AWS, and Docker.
My work ranges from customer-facing SaaS platforms and internal business applications to ERP systems, CRM integrations, booking platforms, and automation workflows. I can take an application from an initial idea or Figma design through architecture, development, testing, deployment, and ongoing improvements.
I also specialize in adding AI capabilities to real applications. I've built production systems using Claude, OpenAI, RAG, Qdrant, MCP, tool/function calling, and CRM integrations including an AI appointment receptionist that performs real booking actions and a Claude + MCP chatbot connected to Bitrix24.
What I can build
→ SaaS platforms and subscription-based applications
→ MVPs and custom web applications
→ Admin panels, dashboards and internal business systems
→ REST APIs and backend systems
→ React / Next.js frontends
→ Node.js / Laravel backends
→ Multi-tenant applications and role-based systems
→ Third-party API and CRM integrations
→ AI-powered features and workflows inside existing applications
→ RAG, AI agents and LLM integrations
→ AWS, Docker and production deployment
I focus on clean architecture, maintainable code and production-ready implementations rather than building something that only works for a demo.
I have a 100% Job Success Score and Top Rated status on Upwork, with experience across real estate, government, e-commerce, training, and business automation.
If you have a SaaS idea, MVP, existing application, or feature that needs to be built, send me the details. I'll tell you how I would approach it and whether I'm the right fit.

Discovery and Knowledge Mapping
