Hi, I'm Rheil

Rheil Evans T. Lunio

I'm a Computer Science student at USTP Cagayan de Oro who builds practical software, and I write research when a problem needs a model instead of a guess. My work ranges from AI prompt tooling and desktop utilities to a published study on blood pressure transitions with its own web application.

I go by RETL online.

About Me: Computer Science student at the University of Science and Technology of Southern Philippines (USTP), Cagayan de Oro. Python developer who also builds for the web with JavaScript, TypeScript and React. Published researcher, with a study that pairs a statistical model with a working web app. Active beyond code, in leadership, public speaking, broadcasting and creative work.

Current focus areas: software development, artificial intelligence, web development, research, UI/UX design and technology

Technology stack. Languages: Python, JavaScript, TypeScript, HTML and CSS. Frontend: React, Vite. Backend: Node.js, Express. AI: Gemini API, Gen AI SDK. Tooling: Git, GitHub, VS Code.

Featured Projects

Click any card to open the repository.

PromptPilot: AI prompt workspace with a library, playground, comparison tools, and analytics. SmartFileOrganizerPro: Python desktop tool that automatically sorts files into organized folders.
CommitQuest: gamified coding challenges with XP, hints, and achievements. DayForm: scheduling platform with customizable templates for daily planning.

Blood Pressure Transition Modeling: my published research and its accompanying web-based application, modeling how blood pressure categories change over time as a basis for hypertension prevention programs.
