Have a vision for your own custom GPT-based assistant? Let’s build it together — I’ll bring the technical firepower, you bring the personality.

Process

1. Free Strategy Call We’ll discuss what kind of AI agent you need — productivity support, therapeutic assistant, educator, etc. — and choose the right features and tone.
2. Agent Blueprint & Prompt Design I’ll create the agent’s personality, capabilities, and memory flow using expert prompt engineering and system design.
3. Build & Integrate I develop your agent using OpenAI’s API, and integrate it with a mobile or web interface using FastAPI, React Native, or your preferred platform.
4. Deliver & Deploy You’ll get the full codebase, deployment-ready build, and instructions. I include post-delivery support to help you launch smoothly.

FAQs

  • Can this AI agent remember past conversations or tasks?

    Yes! I can build in a memory system using Supabase or a vector database, so your agent can recall details, follow up, and improve over time.

  • Can my agent have a specific tone, voice, or role?

    Absolutely. Whether you want a calm life coach, an unrelenting wall-street trader, or a sales-savvy tik tok script writer, I’ll fine-tune the prompts to reflect that personality.

  • Does this come with a mobile or web app?

    Yes — I can deliver a mobile app or a web-based chatbot. You can choose the format based on your needs.

  • Do I need an OpenAI/Gemini/etc API key?

    I can help you set one up, or integrate with an existing key. You’ll own it so you’re in control of usage and billing.
