About

I'm pursuing a Master's in Computer Science at Georgia Tech, specializing in Machine Learning. I'm passionate about building intelligent systems that push the boundaries of what's possible with AI, from semantic search and agentic systems to neural networks that understand human cognition.

Experience

Machine Learning Engineer Intern

Adobe | Adobe Experience Platform

May 2025 – August 2025 | San Jose, CA

Built end-to-end semantic search solution for Adobe's new Audience Agent, generating intent-driven audiences for marketing campaigns using natural language queries and scaling to 20M+ profiles with sub-second retrieval on Qdrant vector database. Invented attribute-based chunking algorithm via agglomerative clustering to intelligently segment user data, raising semantic search success rate to 90%.

Patent pending for chunking-based semantic search solution.
