Data Engineer @ Point72
About
AI Engineer at Replay. I develop full-stack agentic AI solutions to create user-friendly products and optimize internal operations in a fast-paced startup. I regularly use the following tools: Python, TypeScript, AI frameworks like LangChain and Mastra, Vercel, Spark, AWS, LLMs, Linux/Unix, knowledge graphs, and Git, among others. My education is centered on data engineering, machine learning, and economics. I am a senior at BYU finishing a double major with a BS in Machine Learning and a BS in Economics. I spent the 2024 Summer as a Data Engineer Intern at Point72 working on data ingestion, architecture, and search-as-a-service solutions. Learning is my true passion and find great fulfillment in working with other people to find new solutions to challenging problems.
