About Me

ML engineer and full-stack developer based in Auckland, New Zealand

Roshan Aryal — ML Engineer & Full-Stack Developer

I'm a final-year Bachelor of Information Technology student at Otago Polytechnic Auckland, graduating December 2026. I ship real applications — not just coursework — with live deployments on Streamlit, Vercel, and Firebase.

My ML work grew from genuine curiosity into a real specialisation. I built an end-to-end Road Accident Risk Predictor achieving 90.5% R²with Random Forest and GridSearchCV, and I'm actively deepening my stack in Python, scikit-learn, and TensorFlow alongside full-stack web development.

I'm looking to join a team where I can contribute from day one and grow into a strong ML or full-stack engineering role.
