About this gig

Are you tired of AI that "hallucinates" or gives generic answers? You need a Custom AI Agent powered by RAG (Retrieval-Augmented Generation).


With over 15 years of experience in software architecture and serving as a CTO for tech startups, I specialize in building production-ready AI solutions that actually solve business problems. I don't just "connect an API"; I build a secure, scalable knowledge system.


What you will get:

  • Custom RAG Pipeline: Your AI will talk directly to your PDFs, Docx, or SQL Databases.
  • Vector Search Mastery: Implementation using Pinecone, Supabase, or Weaviate for lightning-fast retrieval.
  • Multi-Channel Deployment: Integration with WhatsApp, Telegram, or a custom-built Web UI.
  • Logic & Autonomy: Agents that don't just talk but act (connecting to CRMs, Google Sheets, or Zapier).

Why work with me? I am a senior developer and technical co-founder. I understand that security and accuracy are non-negotiable for your business.
