🍃 About Me 🍃
Name: Jayani Sivakumar
Pronouns: She/Her
School: North Carolina State University
Major: Computer Science
Grad Year: 2027
Location: Raleigh, NC
I’m a Computer Science student at NC State who enjoys building thoughtful, human-centered software. My work blends creativity with engineering, whether I’m shaping AI tools for learning or experimenting with security-focused ML projects.
In the Game2Learn lab, I contributed to MerryQuery, an AI tutor for introductory programming. I worked on training and evaluation workflows to make system explanations clearer, more reliable, and grounded in real course materials.
Recently, I’ve explored phishing and malware detection to understand how classical ML applies to practical security problems.
Outside of class, I support mentorship and community-building through WiCS at NC State. I love working on projects where clean code, iteration, and thoughtful collaboration matter.
