About this gig
Do you need a standard website, or an Intelligent AI SaaS Platform?
I don't just wrap ChatGPT in a UI. I build production-grade AI SaaS applications using sophisticated architectures like RAG (Retrieval Augmented Generation) and Multi-Agent Systems.
Whether you are building an internal tool for data analysis or a customer-facing AI product, I deliver secure, scalable software.
My Specialized Tech Stack:
- The Brain: OpenAI (GPT-4), Anthropic (Claude 3.5), Gemini, Llama 3.
- The Logic: LangChain, LangGraph, CrewAI (for Autonomous Agents).
- The App: Next.js (React), Python (FastAPI/Django), TailwindCSS.
- The Memory: Vector Databases (Pinecone, Weaviate, Supabase pgvector) for RAG.
What I Build:
- Custom AI SaaS: User auth, subscription payments (Stripe), and AI credit systems.
- RAG Knowledge Bases: Chat with your PDF, SQL, or Notion data securely.
- Autonomous Agents: AI that can browse the web, scrape data, and execute tasks.
Why this gig?
- Scalable Architecture: Built to handle 10k+ users.
- Security First: Secure API key management and data privacy.
- Full Source Code: You own 100% of the IP.
