About me
Hi, I'm Abdullah, an AI engineer who builds practical AI tools. I specialize in RAG chatbots that answer from your own documents, AI agents, and LLM-powered apps using Python, LangChain, and Google Gemini. I also fine-tune Hugging Face models, build computer vision apps with PyTorch and MediaPipe, and deliver clean Streamlit or Gradio interfaces. You get tidy, documented code, secure API key handling, and clear communication from start to finish. Send me your idea and let's build it.... Read more

AI & Computer Vision Engineer

Self Employed • Freelance

May 2025 - Present • 1 yr 5 mos

Specialized in building end-to-end Artificial Intelligence, Computer Vision, and Generative AI applications tailored to real-world business and interactive use cases. Key Expertise & Achievements: • Computer Vision & Pose Tracking: Developed real-time computer vision systems using MediaPipe and OpenCV, including an AI Fitness & Gym Coach tracking joint kinematics across 5 exercise routines with sub-second feedback. • Generative AI & RAG Pipelines: Built production-ready Retrieval-Augmented Generation (RAG) systems using LangChain, ChromaDB vector search, and Google Gemini / Groq LLMs to extract insights from complex documents with zero hallucinations. • LLM Fine-Tuning & NLP: Fine-tuned transformer models (Google T5 on Hugging Face) for abstractive text and dialogue summarization. • Autonomous AI Agents: Created intelligent multi-agent systems with tool integration and live web data retrieval. • Full-Stack AI Deployment: Built responsive client-facing interfaces using Streamlit, Gradio, and Python with clean, modular architecture. Focused on delivering clean, well-documented code, high-accuracy models, and responsive client communication.
