Project details
Chatbots just talk. Agents do the work.
If you want to automate complex business workflows, like checking your database, drafting emails based on CRM data, or scraping live market info, you don't need a chatbot. You need an Autonomous Agentic System.
I build secure, "Tool-Using" AI architectures using OpenAI Function Calling and the Model Context Protocol (MCP). This allows the AI to interact with your real-world infrastructure safely.
What I Build:
The Brain: A central Supervisor Agent that plans tasks.
The Hands: Custom Python "Tools" that connect to your APIs (Stripe, HubSpot, SQL, Gmail).
The Guardrails: Strict logic ensuring the Agent never takes sensitive actions (like "Delete") without Human approval.
My Architecture (The Supervisor Pattern):
User Request: "Analyze last week's sales and email me the summary."
Supervisor: Breaks task into "Query DB" + "Analyze Data" + "Draft Email."
Sub-Agents: The SQL Agent fetches data; The Writer Agent drafts the text.
Execution: The system performs the action and reports back.
Tech Stack:
Frameworks: LangGraph, LangChain, PydanticAI.
Integration: REST APIs, SQL, MCP Servers.
Safety: Docker Sandboxing & Human-in-the-loop authorization.

Local LLM Infrastructure Optimization
I had the pleasure of working with Salah on a contract to optimize the local machine LLM, and the results were nothing short of fantastic. From the outset, Salah demonstrated a deep understanding of large language model architectures and the intricacies of hardware performance tuning.

About Salah Eldin
AI Automation & Integration Expert | Custom AI Agents & RAG Chatbots
100%
Job Success
Bilbeis, Egypt - 1:49 pm local time
That gap between "works in a demo" and "works in production" is why most of my clients come to me after something else fell apart. I'm Salah Eldin, an AI engineer with a 100% Job Success Score and Top Rated status on Upwork, 9 projects, 750+ hours, and systems that are still running for the people I built them for.
What I do best:
AI Agents & Automation, Custom agents and multi-agent systems (LangGraph, n8n) that take over repetitive work, with human-in-the-loop approval so the AI never acts on anything important without your sign-off.
RAG Chatbots & Knowledge Systems, Assistants trained on your own documents that answer with citations instead of hallucinating, with strict data isolation so one user's data can never leak into another's.
Voice AI & Integrations, Low-latency voice agents and clean API integrations with OpenAI, Claude, and Gemini. I work natively in Arabic and English, which matters for the MENA market.
How I work: I obsess over the parts clients don't see, error handling, retries, the architecture that keeps your app responsive while the AI thinks. That's the difference between a system you trust and one you babysit. I'm also honest about fit, if I'm not the right person for your project, I'll tell you upfront.
If you're adding AI to your product or replacing a slow manual process with something that runs on its own, send me a message with what you're working on. I'll give you my honest take before you commit to anything.
Steps for completing your project
After purchasing the project, send requirements so Salah Eldin can start the project.
Delivery time starts when Salah Eldin receives requirements from you.
Salah Eldin works on your project following the steps below.
Revisions may occur after the delivery date.
Workflow & API Analysis
I will review your requirements to map out the exact "Action Flow." We will define which APIs the agent needs to access (e.g., SQL, Stripe, Gmail) and the specific permissions required.
Tool & Schema Definition
I will write the custom Python functions (Tools) that connect to your external services. This includes defining strict Pydantic schemas to ensure the AI sends the correct data formats every time.
