About Me

I'm a seasoned Data Scientist and AI Developer with extensive hands on experience in every phase of the data science lifecycle, from the initial problem identification through to model deployment and scaling. I specialize in Generative AI technologies and Large Language Models (LLMs). I have a strong command of a wide range of machine learning tools, especially within the Python ecosystem—think TensorFlow, Scikit-learn, Pandas—and I’m quite skilled in SQL. I'm particularly adept in cloud technologies, focusing on MLOps using Google Cloud Platform (GCP), and I’m experienced in adapting these technologies to solve real business challenges. Over my career, I’ve led numerous data science and AI projects from start to finish. I pride myself on my ability to engage with stakeholders effectively, making complex concepts accessible and ensuring that the solutions we develop align perfectly with business objectives. I’m passionate about using AI to drive nnovation, streamline processes, and create significant value across various industries.
