Improve prompt reliability and quality
This is my 2nd time working with Hamza on my AI prompt. He perfectly solved the problem, was very communicative, and a pleasure to work with. I will continue hiring him for future prompt engineering work!

About Hamza
AI Engineer | Full-Stack Developer | Data Pipelines | LLM Integration
Tunis, Tunisia - 2:57 am local time
I’m an AI Engineer with proven experience leading AI solutions projects—from design to deployment—using state-of-the-art tools like OpenAI GPT-4o/GPT-5, Retrieval-Augmented Generation (RAG), and LangChain. At a fast-growing startup, I led the development of production-ready GPT agents for document automation and diagnostic intelligence, delivering scalable, real-world impact.
✔️I specialize in leveraging Chatbots, AI Agents, Large Language Models (LLMs), RAG pipelines, and advanced prompt engineering to deliver intelligent solutions.
✔️My background spans Data Science, Natural Language Processing (NLP), Computer Vision, and Time Series Forecasting.
✔️I’ve successfully deployed complex machine learning models across cloud platforms like AWS, Azure, and others.

The Extended Version ;)
Pleasure to meet you! I’m Hamza Chebbi, a Tunis-based AI & Software Engineer passionate about LLM agents, document automation, and intelligent systems. I have lead the AI division team at a startup, where I architect and deploy prompt-powered workflows using OpenAI GPT-4o/GPT-5, Gemini 2.5 Pro, and Claude Sonnet 4.
🚀 Real-world Project Highlights:
Document Intelligence System: Built an automated GPT-based pipeline that extracts and structures hotel data from PDFs, DOCX, scanned documents, and images — reducing manual workload by 80%.
Diagnostics Agent: Developed a veterinary diagnosis AI using LangChain and RAG, transforming complex inputs into accurate, JSON-formatted treatment suggestions.
LangSmith Monitoring: Integrated LangSmith to trace agent behavior, evaluate prompt chains, and debug outputs in real time — essential for production reliability.
Frontend + Backend AI Integration: Designed React-based validation UIs with Express.js and PostgreSQL backends to enable human-in-the-loop confirmation before DB updates.
đź’ˇ Why Clients Work With Me:
End-to-End Thinking — I understand the full pipeline: prompt design, LLM behavior, API handling, frontend/backend delivery.
Prompt + Structure Focused — I create reusable, controlled prompts that always return clean structured output and adapt to evolving needs.
Team-Ready — I’ve worked in agile sprints and documentation-heavy environments. Communication is clear and delivery is fast.
🧠My Tech Toolbox:
AI/LLM Stack: OpenAI GPT-4o, GPT-3.5, Claude, Gemini, LangChain, LangSmith, RAG, Vector DBs (Pinecone, FAISS)
Prompt Engineering: Few-shot, zero-shot, tool use, JSON structuring, output consistency strategies
Languages & Frameworks: Python, JavaScript, TypeScript, React, Node.js, Next.js, Express, Java, C, R
Cloud & DevOps: Docker, Azure, AWS, Git, REST APIs, PostgreSQL, MySQL
Visualization & BI: Power BI, Dash, Excel VBA
Statistical Modeling: Time Series Forecasting (ARIMAX, SARIMAX), GARCH/ARCH, Experimental Design
