About this gig

Looking to add AI to your app but not sure where to start? I can help you build and integrate it properly.


I'm a software engineer with 2 years of experience building production applications including AI-powered content pipelines and large-scale search systems handling 290M+ records.


I've worked with OpenAI, Claude, and Perplexity models and understand what it takes to build reliable AI features including API integration, database connectivity, retry logic, fallback handling, and production-ready implementation.


What I can build for you:

  • AI chatbots for your website or application
  • RAG systems that let AI answer questions using your own documents and data
  • AI-powered search across your database or knowledge base
  • LLM integrations using OpenAI, Claude, or other supported models
  • Database-connected AI that works with real-time application data
  • Clean, documented code that your team can maintain and extend


Whether you need a simple chatbot or a full custom AI system, I bring real production experience to every project not just theory.


Message me before ordering if you have questions about your specific project. I'm happy to discuss scope before you commit to a package.
