About

I am Mhar Nhel Valentin, a 25-year-old web developer and data science enthusiast currently pursuing a Master of Science in Data Science. I hold a Bachelor of Science in Information Technology and have extensive experience building full-stack web applications. My skill set spans modern web technologies, backend APIs, and data analysis — including forecasting and exploratory analysis using Python with Jupyter and R with RStudio. I also practice AI-assisted development using tools like Claude Code, Cursor, and Codex — leveraging AI to ship faster and smarter.
