Informatics student in Medan. I build web apps and machine-learning projects, and I care about how they look.

About

I like projects where a model, an interface and a bit of design all have to work together.

I study Informatics Engineering at Unika Santo Thomas in Medan, with a focus on programming, AI engineering and machine learning. My thesis is about classifying disaster status.

Away from code and screens, I go back to drawing.

Code
Web apps in JavaScript, React, Next.js, Python and Flask. Vervin, CRUD Cura and Keppo are the ones to look at.
AI
A convolutional network for face matching, a quantum-physics chatbot and a backpropagation demo. Disaster-status classification for the thesis.
Design
Interfaces for my own projects, third place in a web design competition, and visual content for the faculty student board.

Selected work

Six projects across web apps and machine learning. Each one links to its source code, and five have a live demo.

Natural language processing

Quantum Bot

A chatbot that explains quantum-physics concepts. It runs as a web page and answers inside a game-style dialog box.
