Arun Karthikeyan

I'm Arun, a Computer Science undergraduate at VIT Chennai (AI & ML specialization, class of 2027), spending most of my time in the space between research and shipped software.

Recent work spans a PPO-based dynamic pricing engine with SHAP explainability, an STGCN traffic forecaster benchmarked against LSTM and Graph WaveNet, a real-time hand-tracking whiteboard, and full-stack products built with Flask, React, and Next.js.

I like problems where a model's output has to survive contact with a real interface — so I build both halves myself.
