You will get I will build a custom AI chatbot with GPT-4 or Claude for your business
Project details
You'll get an AI application development that actually understands your business — not a generic FAQ bot that frustrates your customers.
I recently built ChainHub, a platform connecting 500+ AI models in production, and I integrate LLMs like GPT and Claude into real products regularly.
What makes this different:
• Trained on YOUR content using RAG — accurate answers, not hallucinations
• Multi-turn conversations that actually understand context
• Human handoff for the edge cases a bot shouldn't handle
• Clean integration into your website, WhatsApp, Slack, or platform
I'm a senior AI and full-stack developer with a background at Samsung R&D. I communicate clearly, deliver on time, and you'll see working progress before final delivery — not just at the end.
Message me before ordering so I can confirm the right scope and tier for your specific use case.

About Max
AI & Full-Stack Developer | LLM Integration, Web Apps, Automation
Hanoi, Vietnam - 2:10 am local time
Over 10 years I've shipped production systems as a CTO and senior engineer, including work at Samsung R&D. Today I focus on:
- AI Integration — connecting GPT-4o, Claude, and other LLMs into real products: RAG systems, AI assistants, document processing, and workflow automation
- Full-Stack Development — React, Next.js, Node.js, Python/FastAPI — from MVP to production-grade web applications
- Process Automation — eliminating repetitive manual work with custom automation, not brittle no-code tools
- System & API Integration — connecting the tools businesses already use so data flows automatically
What you get working with me:
- Clear communication and weekly progress you can actually see
- Senior-level work — I write the code, I don't hand it to a junior
- Realistic timelines and honest scoping. If something won't work, I tell you upfront
I've led engineering teams, architected systems from scratch, and delivered for startups and established businesses across fintech, e-commerce, and SaaS.
Tech I work with daily:
Languages: Python, JavaScript/TypeScript, C/C++, Rust
Frontend: React, Next.js, Vue.js
Backend: Node.js, FastAPI, REST/GraphQL APIs
AI/ML: OpenAI, Claude, LangChain, RAG, prompt engineering
Cloud: AWS, GCP, Docker, CI/CD
Tell me what you're trying to build or fix — I'll tell you honestly whether I can help and how.
