⭐⭐⭐⭐⭐ “Nabi is terrific. His programming is first rate, but he also does a lot of little things to make the experience world class. I am very grateful to him and I’ve worked with him extensively across several assignments.” — David Glenn, Founder, Western Heritage Capital, LLC I’m an AI Engineer with 4+ years of experience across 150+ AI/ML projects, including 30+ end-to-end AI systems. My core strength is Machine Learning, Deep Learning, and Computer Vision, while my recent work focuses heavily on LLMs, AI Automation, Agentic AI, and production-ready intelligent systems. I work with startups, founders, researchers, individuals, and businesses that need more than a simple prototype. Whether the goal is AI agents, LLM applications, OCR pipelines, computer vision systems, or custom ML/DL models, I can build the full solution from idea to deployment. ✅ AI Engineering Services - AI Agents and Agentic AI systems - Multi-agent systems and task orchestration - AI Automation for business processes - Automated workflows using LLMs - AI Chatbots and Conversational AI - Knowledge assistants and retrieval-based AI systems - Internal copilots and domain-specific assistants - Prompt engineering and structured prompting - Tool-calling and function-calling systems - OpenAI API integrations - LangChain and LangGraph applications - CrewAI and OpenClaw-based workflows - n8n AI automations and custom pipelines - LLM fine-tuning and model customization - Multimodal AI applications - Document AI and intelligent information extraction ✅ Machine Learning & Deep Learning - Custom ML model development - Deep learning model design and training - Fine-tuning and optimization of models - Classification, regression, clustering, and forecasting - NLP systems and text intelligence - Data preprocessing, feature engineering, and evaluation - Training, inference, and experimentation pipelines - Research-driven AI solution development ✅ Computer Vision, OCR & Edge AI - Object detection and tracking - OCR and document processing systems - Image classification and segmentation - YOLO, OpenCV, and PyTorch-based vision solutions - Real-time computer vision applications - Visual inspection and intelligent image analysis - Edge AI deployment on NVIDIA Jetson and Raspberry Pi - High-speed detection systems for practical business use cases ✅ Tools & Technologies - Python, PyTorch, TensorFlow, OpenCV, Hugging Face - OpenAI API, LangChain, LangGraph, CrewAI, OpenClaw, n8n - FastAPI, REST APIs, workflow integrations, deployment pipelines - Vector databases, MySQL, PostgreSQL, Neo4j - Docker, AWS, GCP, Azure, cloud-based AI deployment - Edge AI deployment with NVIDIA Jetson and Raspberry Pi ✅ Selected Projects - Agentic RAG Application: Built a retrieval-based AI system with a Streamlit frontend and FastAPI backend for grounded responses, workflow-driven interaction, and scalable deployment. - Invoice Intelligence System: Fine-tuned Mistral 7B using QLoRA to build a local application that extracts structured data from raw invoice images, PDFs, or text for downstream database integration. - AI-Powered Medical Coding System: Fine-tuned RoBERTa on MIMIC-IV clinical notes and built an application that predicts ICD-10 codes from text, PDFs, and images. - Credit Card Fraud Detection System: Built an ML/DL-based application to analyze transaction data and predict fraudulent activity through an interactive interface. - Cutlery Detection Edge AI System: Fine-tuned YOLOv8 for 18 types of cutlery and deployed it on NVIDIA Jetson Nano for high-speed detection and counting in real-time. ✅ Why Clients Hire Me - Strong core foundation in ML, DL, and Computer Vision - Modern expertise in LLMs, automation, and agentic AI - Ability to build full A to Z solutions, not just isolated parts - Clean, reliable, and production-focused implementation - Clear communication, ownership, and serious attention to detail ✅ What You Can Expect - Structured and professional workflow - Clean and maintainable code - On-time delivery - Practical solutions focused on real use - A dependable long-term technical partner Let’s collaborate and build something extraordinary.
