What I'm looking for

I seek an early-career data science role where I can apply Python and ML skills, work on production-ready models and APIs, collaborate in cross-functional teams, and continue learning in a growth-focused environment.

I am an applied mathematics student and aspiring data scientist with hands-on experience building predictive models and end-to-end systems that deliver practical business value.

I developed an Air Alert Forecasting System using streaming data and a state algorithm that achieved a 90% recall, and exposed it via a scalable AWS service and RESTful Flask API.

I also designed and implemented a RAG system for contextual code generation leveraging ChromaDB, Qwen2.5, LangChain and Reciprocal Rank Fusion to improve search quality and answer precision.

I work primarily in Python and related data tooling (Scikit-learn, Pandas, NumPy) and am a quick learner and collaborative team player committed to continuous growth and building precise, efficient analytical solutions.
