Project details

Many businesses already have a working app, SaaS platform, CRM, admin panel, or internal system - but struggle to add AI features that are actually usable in production.

I help existing app owners integrate OpenAI, Claude, or Gemini into their current system with a practical, production-ready approach.

I can help you build:
• AI Chat Features
• AI Email & Reply Generation
• AI Content Automation
• AI Smart Search / Knowledge Base
• AI Workflow Automation
• AI Translation & Summarization
• Dify AI Workflow Integration
• Internal AI Tools for Teams
• AI Assistants for SaaS or CRM platforms

I work with:
• React / Next.js
• Node.js
• Laravel / PHP
• Ruby on Rails
• Python / Django
• REST API / Webhooks
• Dify / LangChain

This project is ideal if:
• You already have an existing product
• You want to launch AI features quickly
• You need help choosing the right AI model
• You want production-ready implementation, not just prototypes

Please contact me before ordering so I can review your current system and recommend the best AI integration approach for your business.

Hanoi, Vietnam - 1:17 am local time
I help startups and businesses build high-quality products from MVP to production-ready with a dedicated team behind me to move fast and ship reliably.

Beyond mobile, I bring a strong focus on AI-native development: using tools
like Claude, Cursor, and AI agents not just as coding assistants, but to
automate business workflows, clarify requirements faster, and reduce
development time significantly. My strength is knowing where AI creates real
productivity gains and where traditional engineering is still the right call.

With 20+ years in software development and experience serving clients across
Japan, the US, the EU, Australia, and Asia Pacific, I understand how to work across
different business cultures, communication styles, and project expectations.
