What I'm looking for

I seek roles where I can build interpretable ML solutions and scalable data pipelines, work in collaborative teams, and drive measurable business impact while continuing to grow technically.

I am a Master's student in Computer Science with hands-on experience building end-to-end data pipelines, predictive models, and scalable system integrations. I focus on applying interpretable machine learning and statistical analysis to solve practical problems.

My projects include architecting PostgreSQL-backed systems, containerized deployments with Docker, and NLP work using transformer models (BERT, DistilBERT, RoBERTa) with explainability methods such as LIME and SHAP. I have improved model accuracy and interpretability while optimizing training workflows.

I have delivered measurable business impact through forecasting and segmentation projects, including a customer-behavior analysis and sales-forecasting work that produced ROI improvements. I also publish research on medical image analysis and applied ML techniques.

I bring strong technical skills in Python, PyTorch, SQL/PostgreSQL, and data visualization tools, combined with collaborative soft skills and a proactive attitude. I am eager to contribute to software development and digital transformation initiatives in an engineering or data-science role.
