Productivity Tools

Tools That Solve Real Problems

Every tool here was built to solve a specific workflow challenge, from classroom management to job hunting. Designed for practical, daily use in professional environments. Source code available on GitHub.

Classroom & Workflow Tools

Built and tested during my time teaching high school. These tools handle attendance, group management, and student engagement efficiently.

Games

Games Built With Purpose

Every game started with a frustration: ads, paywalls, or mechanics that just did not feel right. So I rebuilt them the way I always imagined they should be. All games are playable in-browser.

Classic Games, Reimagined

Familiar games with thoughtful twists. No ads, no paywalls, just clean gameplay with unique mechanics.

More Projects

Other Things I Have Built

Additional projects that showcase range, from game prototypes to classroom utilities. Available on my itch.io or built for specific use cases.

Game / Python / Pygame
Block Breaker Simple

Breakout-style game with powerups (explode, pierce, split) and an auto-aim homing mechanism when 90% of blocks are cleared. No more watching the ball bounce endlessly.

Game / Python / Pygame
Chess Basic

A minimal chess board with drag-and-drop pieces. No rule enforcement, just a clean board for freeform play, experimentation, or teaching.

Tool / Python / Tkinter
Group Sorter (Manual)

Drag and drop names into colored group boxes. Double-click to rename, paste lists from clipboard, save and load sessions. Prevents anyone from being forgotten or double-placed.

Tool / Python / Tkinter
Skripsi Title Database

Research paper management tool for students with submission form, admin review dashboard, and draft generator. Built to streamline the skripsi/thesis process in my classroom.

About

Who I Am

I am a self-taught Python developer and indie game creator based in Depok, West Java. My background is in Industrial Engineering (President University, 2023) which means I think in systems, processes, and optimization.

I got into programming because I was tired of simple mobile games being ruined by ads and paywalls. So I started building my own: clean, focused, and actually fun.

I also spent a year teaching Python and Informatika to high school students, which taught me how to explain complex things simply and build tools that solve real classroom problems.

Currently expanding into data science and machine learning through Kaggle certifications, while continuing to build and publish games and productivity tools.
