## Headline

Lead Data Scientist at Sapien\+AI

## About

I have \~3 years of experience working in a high\-frequency trading \(HFT\) environment, where I developed a strong foundation in handling large\-scale data and using it to drive business decisions—such as building and evaluating trading strategies\. Through this experience, I’ve learned how powerful data can be in shaping real\-time decisions and outcomes\. I’m now expanding into Generative AI and Agentic AI systems to explore broader data\-driven applications and deepen my understanding of how data impacts different domains\. Currently, I’m building: • Multi\-file RAG \(Retrieval\-Augmented Generation\) systems • Agentic AI workflows for autonomous problem\-solving • LLM\-based applications integrating structured and unstructured data Where I can contribute: • Turning complex data into actionable business insights/decisions • Building scalable data pipelines and AI\-driven systems • Applying ML/AI to support decision\-making across domains • Developing intelligent, production\-ready data solutions I’m interested in roles where I can apply data and AI to make meaningful, real\-world impact on decision\-making\. Let’s connect if you’re working on data or AI\-driven problems\.
