My Portfolio
FAQ
Which AI models can you integrate?
GPT-4o, GPT-4, GPT-3.5 Turbo, Claude, Gemini, Llama, Whisper for voice, DALL-E for images, and Stable Diffusion. I work with any model that has an API.
Can you add AI to my existing app?
Yes. Share your current codebase and I'll integrate the AI feature cleanly without breaking your existing code.
Will the AI remember previous conversations?
Yes. I implement full conversation history with proper context window management so the AI remembers context across the session.
Can you build a custom AI trained on my data?
Yes — using RAG (Retrieval Augmented Generation) with vector databases like Pinecone. Your AI can read your documents, websites, or knowledge base and answer questions from that data.
How do I keep my OpenAI API costs low?
I implement token optimisation, response caching, and smart context trimming to keep your API costs as low as possible without sacrificing quality.
