𝗔𝗩𝗔𝗜𝗟𝗔𝗕𝗟𝗘 𝗧𝗢 𝗦𝗧𝗔𝗥𝗧 | 🏅 Expert-Vetted AI Developer & AI Engineer | 💰 $300K+ Earned on Upwork 9+ Years in AI & Machine Learning | 100+ AI & Data Projects | 2,500+ Hours | 10+ Industries Hello, I'm Orhan. I am an AI Developer and AI Engineer with a PhD in Artificial Intelligence, 9+ years of experience and 100+ AI and data projects delivered across 10+ industries. Across 65 Upwork jobs and 2,500+ hours I have held a Expert-Vetted status. If you want an AI Developer who ships models into production instead of leaving them in a notebook, that is the work I do every day. WHAT CLIENTS HIRE ME FOR - Machine Learning models for prediction, forecasting and classification - AI-powered software products, APIs and internal tools - Natural Language Processing: semantic search, extraction, document processing - Computer Vision: image classification, object detection, automated analysis - Data Visualization dashboards and decision-support reporting - AI automation that removes manual steps from a daily workflow RESULTS I HAVE DELIVERED - As a Machine Learning specialist I improved model performance by up to 35% through feature engineering and stronger data preparation. - As a Machine Learning specialist I improved prediction accuracy by up to 25% across classification, forecasting and decision-support systems. - As an AI Engineer I cut data processing and analysis time by up to 60% with automated Python and SQL workflows. - As an AI Engineer I improved model inference speed by up to 40% through architecture and performance optimization. - As a Data Visualization expert I reduced manual reporting work by up to 70% with automated dashboards. - Combining Machine Learning and Data Visualization, I cut the time from raw data to a decision by up to 50%. HOW I WORK AS AN AI DEVELOPER I cover the full Artificial Intelligence lifecycle across 7+ stages: data preparation, model development, evaluation, integration, deployment, monitoring and continued optimization. As an AI Engineer I connect models to web applications, APIs, databases and operational workflows, so you get a working system rather than an isolated experiment. I will also tell you when a problem does not need Machine Learning at all, which usually saves the larger half of the budget. MACHINE LEARNING My Machine Learning work covers 7+ use cases: classification, regression, forecasting, segmentation, anomaly detection, recommendation systems and pattern recognition. I work across both Supervised Learning and Unsupervised Learning, from data preparation and model selection through training, validation and production integration. NLP AND COMPUTER VISION My Natural Language Processing work covers 6+ areas including text classification, semantic search, information extraction, sentiment analysis, document processing and language automation, built with OpenAI models, LangChain, RAG pipelines and agentic AI workflows. My Computer Vision work covers 4+ areas including image classification, object detection, visual recognition and automated image analysis. DATA VISUALIZATION As a Data Visualization expert I have delivered Power BI and analytical dashboard projects valued at $8K+, covering real-time reporting, KPI visualization and operational analytics. My Data Visualization work turns Machine Learning and Data Analysis output into dashboards and reports a non-technical team can act on. MY STACK - AI and ML: Python, TensorFlow, PyTorch, Keras, Deep Learning, Artificial Neural Networks - Data: SQL, databases, Data Analysis, Data Science, Data Visualization - Engineering: APIs, Node.js, PHP, Angular, HTML, CSS, Git, Amazon Web Services WHAT I HAVE SHIPPED As an AI Developer I have delivered $20K+ image-processing systems, $10K+ AI-powered software platforms, Machine Learning prediction systems, AI automation products and production analytics tools across 10+ industries. WORKING WITH ME - One AI Developer owns the work from raw data to deployment. - You get short written updates and honest estimates, including when a model will not reach the accuracy you want. - I hand over documented code and a model your own team can retrain. - Across 2,500+ hours as an AI Developer I have held a 100% Job Success Score and Expert-Vetted status. Whether you need an AI Developer, an AI Engineer, a Machine Learning specialist or a Data Visualization expert, send me a message describing the problem and the data you have. I will tell you what is realistic, what it will cost, and whether Machine Learning is even the right tool, before you commit.
