Description

As an AI Architect and Senior Machine Learning Engineer, I combine strategic thinking with hands-on implementation. My expertise ranges from designing scalable data architectures to building production-ready ML systems such as recommendation engines, plausibility checks for form validations, geospatial analytics for renewable energy, and clickstream-based personalization. I specialize in Recommender Systems, Big Data solutions, and Generative AI, and bring deep experience with Python (pandas, scikit-learn, NumPy), Spark, SQL, and MLOps tools like Kubernetes, Airflow, and Docker.

I don’t just build models, I design complete data solutions, ensuring data is structured, validated, and deployed efficiently to maximize business value. Whether creating AI platforms from scratch or optimizing existing pipelines, I deliver measurable impact through robust, scalable solutions.
