I have been working as a freelancer on Fiverr for around 6 years, helping clients build machine learning, data science, computer vision, NLP, Generative AI, RAG, chatbot, LLM fine-tuning, AI agent, and automation projects. So far, I have completed 196 orders for 124 unique clients from different countries. Most of my work starts with a client’s data, idea, or business problem, and I help turn it into a working solution. My projects have included data cleaning, exploratory analysis, feature engineering, model training, model evaluation, forecasting, classification, regression, object detection, image processing, document search, chatbot development, backend API integration, and deployment. I have worked with Python, PyTorch, TensorFlow, OpenCV, Scikit-learn, Hugging Face, LangChain, FastAPI, Django, vector databases, and cloud-based deployments. My focus has always been to deliver practical work that clients can understand, test, and use.
