About this gig
Please contact me first before placing an order. Don't just build a wrapper. Build a defensible AI SaaS business. I am a Fractional CTO and SaaS Founder. The market is flooded with "AI wrappers" that break when API costs rise. I build Architected AI Solutions systems designed for scalability, context management, and real business value
I am not a volume agency. I build a money making machines:
- RAG (Retrieval-Augmented Generation) Systems: Chat with your PDF/Data
- B2B AI Dashboards: Automate workflows using LLMs (OpenAI, Claude, DeepSeek)
- Generative Content Platforms: Text, Image, or Data generation tools
- Internal Business Intelligence: Private AI tools for company data
AI Tech Stack:
- LLMs: OpenAI (GPT-4), Anthropic (Claude), Llama (Local/Open Source).
- Vector DBs: Pinecone, Supabase pgvector.
- Framework: Next.js, Python (FastAPI), LangChain
Why This Service?
- Direct Access: You speak to the Lead Architect, not a PM

FAQ
Do I have to pay for OpenAI/Anthropic API costs?
Yes. You will need your own API keys from OpenAI, Anthropic, or other providers. These costs are usage-based and paid directly to them. I will optimize the code to minimize token usage, but the monthly operational cost of the AI intelligence is you
Can I build a full AI SaaS with the Basic Package ($500)?
No. The Basic Package is for Integration Only (e.g., connecting ChatGPT to an existing form) or a simple script. A full AI Application with user login, database memory, and history requires the Standard or Premium package. Please message me first to confirm your scope
Will my data be used to train the public AI models?
Generally, no, provided we use the commercial Business/Enterprise APIs (like OpenAI API), which explicitly state they do not train on API data by default. We build your architecture to ensure user data remains isolated within your database and is only sent to the AI when necessary for processing
What technology do you use for AI Apps?
I use Next.js (React) for the frontend and Node.js or Python for the backend. For memory and context (RAG), I use Vector Databases like Pinecone or Supabase (pgvector). This ensures your AI isn't just a "chatbot," but a system that can actually "remember" and reference your specific business data
What happens if the AI API changes or updates?
I provide a 30-Day Technical Warranty to ensure everything works as delivered. However, the AI landscape moves fast. If OpenAI releases a major breaking change months later, I offer Retainer/Maintenance Packages
