D Defoe L. Building systems, breaking them on purpose.
Information Systems student at Universitas Ciputra. I build web, mobile, and data tools — and write about what they teach me. Currently exploring a double degree at Fontys.
Things I’ve built or am building.

A multi-role registration platform built with a 4-person team. In active development.

A native Android reader app. Built in Android Studio.
read case study →Data Engineering Stack
An end-to-end analytics pipeline. dbt models, BigQuery warehouse, DuckDB locally.
read case study →Notes on becoming, frameworks, and warmth.
Three living documents: a self-becoming codex, a tactical warmth codex, and a collection of guides. They’re how I try to make sense of the gap between who I am and who I’m becoming.

Who’s behind this.
“No matter how much a person tries to control their surroundings, there are always imperfections.”
I’m Shika — Information Systems for Business at Universitas Ciputra Surabaya. I build across stacks: Laravel + Alpine on the web, Kotlin on Android, dbt/BigQuery/DuckDB for data. I also mentor freshmen in beginner programming and coordinate group-specific mentoring sessions.
Outside of school: leverless fighting game controllers, Indonesian stock market analysis, a Roblox survival game, and three codices in progress.
