About Me

I am a Data Scientist with a strong foundation in machine learning, statistical modeling, and data analysis, focused on building data-driven systems that are both theoretically sound and practically deployable. My work spans time-series forecasting, computer vision, and applied research, with hands-on experience across the full machine learning lifecycle.

I have worked extensively with real-world datasets, designing end-to-end pipelines that involve data preprocessing, feature engineering, model development, evaluation, and deployment. My technical experience includes deep learning models such as LSTMs and CNNs, as well as classical machine learning techniques for structured data and predictive analytics.

In addition to applied industry projects, I have research experience and a published research paper, reflecting my interest in rigorous experimentation and analytical thinking. I am actively seeking roles in data science, data analysis, machine learning, and research, where I can contribute to impactful data-driven decision-making while continuing to grow as a practitioner and researcher.
