About this gig

Want to add AI to your business a chatbot, an AI-powered app, or workflow automation?

I build custom AI applications using OpenAI's GPT-4o and other LLM APIs, backed by 6+ years of full-stack development experience in Laravel, PHP, and Next.js. You get more than a basic chatbot demo a production-ready application with proper backend, database, and deployment.

What I build:

  • Custom AI chatbots for websites, WhatsApp, or Telegram
  • AI-powered SaaS tools and dashboards
  • Workflow automation using GPT-4o and other APIs
  • AI features added to your existing website or app
  • E-commerce and trading/finance AI assistants

How I work:

I write clean, secure, well-documented code and handle the full stack API integration, database design, and server deployment on AWS. You'll get regular updates throughout the build, not silence until delivery.

Message me before ordering so we can scope your specific use case and I can recommend the right package.
