Level 2
Gig Summary
About this gig
With 150+ 5-Star Reviews, I engineer AI solutions that eliminate manual bottlenecks. I don't build generic chatbots; I architect autonomous AI agents and workflows that think, remember, and execute complex tasks.
️ What I Build:
- Autonomous Agents: Advanced logic, memory (Redis/Vector DBs), API execution & voice/vision capabilities.
- Agentic Workflows: Multi-agent systems (LangGraph/AutoGen) collaborating to handle dynamic, multi-step processes.
- Smart Automations: n8n pipelines bridging custom AI with your CRM, Slack, Stripe & databases.
- Robust Backends: Fast, scalable Python/FastAPI architectures.
- Custom Agentic & Data Systems.
- AI-Powered Custom Web Apps
Proven Use Cases:
- Multi-Agent Task Forces: AI teams researching, writing & executing projects step-by-step.
- Voice/Multimodal Agents: AI automating local business reservations & customer service.
- RAG Knowledge Bots: Agents querying massive PDFs via vector databases (Pinecone/FAISS).
- Lead Gen: AI that autonomously qualifies intent & syncs to CRMs.
Stack: Python, FastAPI, LangChain, LangGraph, AutoGen, n8n, Redis, Gemini, GPT-4o, Claude

FAQ
What is the difference between a standard chatbot and an AI agent?
A standard chatbot just answers questions based on fixed scripts. An autonomous AI agent can actually do work—it remembers past interactions, reasons through complex problems, and executes multi-step tasks like qualifying a lead, booking a calendar, or updating your CRM without human intervention.
Can the AI connect to my existing software (CRM, Slack, Notion, etc.)?
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 FastAPI (Python), Node.js (Express), , or serverless functions, handling AI calls, memory, tools integrations, databases, and API endpoints.

Ongoing collaborationShaun 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.
