Hi, I'm Valerie!
Final year NUS Data Science & Analytics student
I'm currently exploring the fields of data science and analytics, with hands-on experience in projects involving Retrieval-Augmented Generation (RAG), knowledge graphs, OCR, and prompt engineering.
Outside of tech, you'll probably find me playing table tennis or figuring out piano chords by ear.
If you're curious about my work or just want to connect, feel free to reach out!
