About

As a Senior Data Scientist and AI Engineer with over 8 years of experience, I have built and scaled machine learning systems applicable to real-world production environments. I enjoy working across the entire lifecycle, from data exploration and predictive model development to the deployment of stable and scalable services. I have gained experience in various fields, including demand forecasting, user behavior modeling, and experimentation, and I build accurate and meaningful models based on a statistical foundation.

Furthermore, I possess a solid engineering mindset honed through experience in backend development, data pipelines, and MLOps. I place great importance on making a positive impact on the real world through my models. I aspire to contribute in diverse areas, such as improving decision-making, optimizing systems, and accelerating team workflows using better data. I am passionate about transforming complex problems into practical solutions applicable to real-world production environments.
