What I'm looking for

I’m looking for an applied data science role where I can build end-to-end AI/ML and LLM-driven solutions (NLP, computer vision, BI) on cloud platforms and partner with stakeholders to deliver measurable ROI.

I have been working as an applied data scientist at PersuMedia since 2021, designing and deploying end-to-end AI, Machine Learning, and Business Intelligence solutions both offline and on cloud platforms. I translate real-world problems into formal models and build practical, scalable ChatGPT and GenAI solutions.

I integrate multilingual natural language processing (NLP) capabilities to improve global applicability, and I develop predictive computer vision models using research-based techniques and engineered prompts for large language models (LLMs). My work achieved a 35% increase in marketing ROI and reduced business costs.

I focus on improving model performance through data quality enhancements, refined feature engineering, hyperparameter tuning, and selecting optimal models—driving up to a 50% improvement in model accuracy. I also build Tableau UI/UX to help stakeholders visualize key metrics and improve insights accessibility and usability, contributing to an estimated 20% improvement.
