FAQ
What exactly is a Full Stack AI Agent?
A Full Stack AI Agent is an AI system that can understand, reason, take actions, and interact with users or tools. It includes everything from the backend (logic, APIs, memory, tools) to the frontend (dashboard, chatbot UI, voice interfaces, etc.).
Can you integrate my AI agent with tools like Slack, Notion, Google Sheets, or APIs?
Yes! I can integrate your agent with third-party tools like Slack, Notion, Google Workspace, CRMs, and custom APIs to automate tasks, send alerts, or retrieve and update data.
Will my AI agent have memory and understand context?
Absolutely. I implement memory using vector databases (Pinecone, FAISS, Chroma) or persistent storage. This enables long-term context and personalized conversations.
What technologies do you use?
I use Popular GPT'S OpenAI,Gemini, Claude, LangChain, AutoGen, FastAPI, Node.js, React, TypeScript, and vector DBs. I choose the stack based on your goals — balancing performance, cost, and future scalability.
Can the AI agent run 24/7 or be hosted in the cloud?
Yes. I can deploy it on platforms like Vercel, Render, AWS, or your server. I’ll also provide setup scripts and hosting guidance.
Can you build a voice-based or multi-modal AI agent?
Yes, I can integrate voice input/output, file upload handling (PDF, CSV), and even camera/image processing depending on your use case.
Will I get the full source code and deployment guide?
Yes, you will receive complete source code, setup documentation, and optional post-delivery support depending on the package.
Which frontend technologies do you use?
I typically use React.js, Next.js, or React Native for building fast, interactive user interfaces like chat windows, dashboards, or mobile apps for your AI agent.
What backend technologies are involved?
Backend is usually built with Node.js (Express), FastAPI (Python), or serverless functions, handling AI calls, memory, tools integrations, databases, and API endpoints.

Shaun was exceptional! He took ownership of the project, we were brainstorming together, he made valuable suggestions and implemented them. He was also very patient with me even when I wasn’t clear about some requirements. He went above and beyond and the final delivery exceeded my expectations. I recommend him for coding and AI automation related jobs.
