Zakaria H.

LLM Engineer and Generative AI Specialist with 8+ years of experience building AI automations, chatbots, RAG systems, and AI agents for real-world business applications. I design and deploy production-ready LLM applications using LangChain, LlamaIndex, OpenAI APIs, and vector databases like Pinecone, Weaviate, and Qdrant. My focus is on delivering reliable, scalable, and high-accuracy AI solutions. 🔹 What I can help you build • LLM-powered applications (GPT, Claude, open-source LLMs) • RAG (Retrieval-Augmented Generation) systems for private data • Use OpenClaw (ClawdBot) to build AI automation workflows • AI chatbots for customer support, legal, medical, or business use • AI agents and multi-step autonomous workflows • Semantic search engines and embeddings pipelines • Prompt engineering and LLM optimization • Fine-tuning LLMs with HuggingFace • Open-source LLM setup with vLLM or Ollama • AI automation and RPA with UiPath 🔹 Technical Stack • LLMs & GenAI: OpenAI, Claude, HuggingFace, LangChain, LlamaIndex • Vector DBs: Pinecone, Weaviate, FAISS • NLP: SpaCy, NLTK, BERT, AraBERT, Gensim • Backend: Python, FastAPI, Flask • Databases: MongoDB, MySQL, Elasticsearch • Deployment: Docker, server deployment, Replicate (Cog) • RPA: UiPath (Certified Advanced Developer) 🔹 Selected GenAI Projects AI Agent Planner & Executor : Built an AI agent capable of handling complex multi-step tasks using function calling, planning, and self-evaluation for reliable results. RAG Document Search System : Developed a RAG system for PDFs, DOCX, and PPTX files with access control and department-based retrieval using Weaviate. SQL AI Assistant (SQLytics) : Created an LLM-powered tool that converts natural language into SQL queries and retrieves accurate database insights. Legal AI Chatbot : Built a chatbot connected to legal database with source-backed answers via text and voice. 🔹 Why work with me? • Production-ready AI solutions (not just prototypes) • Vibe coder: using Cursor AI and Claude Code • Clean, scalable architecture • Strong communication and reliability • Focus on real business value If you need a serious LLM/GenAI expert to build high-quality AI solutions, I’d be glad to help.
