Wiser Locker

Private photos and videos, encrypted on your device and organized by tags instead of folders.

An Android app for people who want to keep private media safe and still find it easily.

Media is encrypted on the device, and access is protected by biometrics and secure key storage.
Multiple tags and saved filters replace a single folder tree, so one photo can belong to "travel", "family", and "friends" at once.
Published on Google Play and maintained under the ForgerWise brand.

FoodList

Less household food waste: know what you have and what to use first.

Food at home often goes to waste simply because people forget what they have and when it expires. FoodList is a household food-management app that keeps track of both.

Problem: about 60% of global food waste happens in households (UNEP Food Waste Index Report 2024), often because people forget what they have and when it expires.
Solution: register ingredients once; green, yellow, and red status shows what is fine, what to use soon, and what has expired.
Background reminders before items expire, full offline use with local storage, and a multilingual UI.

Galaxization

A whole galaxy that evolves on its own, right on your desktop. Your galaxy, yours to watch!

You are the technician of a deep-space observatory, with one rule: look, don't touch. The galaxy turns slowly on your wallpaper while centuries pass as you work — grab a coffee and a dynasty may have fallen. Zoom from the whole galaxy into a single star, then down to a living world. No winning, no reloading, no do-overs: every galaxy writes a history of its own.

History that writes itself: 124 branching technologies, a dozen-plus governments and revolutions, faiths with 16 doctrines and 103 schools of thought, treaties and betrayals, spies, vassals, plagues, and 15 wonders, each with causes and consequences, recorded as a searchable, rewindable chronicle in four languages.
Written from scratch in Rust by AI coding agents, with no game engine and wgpu rendering (DirectX 12 / Metal / Vulkan): a real-time galaxy of 200,000 stars that opens in seconds, runs smoothly on integrated graphics, and pauses when windows cover it.
Deterministic across platforms (the same universe writes the same history on Windows, macOS, and Linux), a second monitor becomes the observatory console, an orchestral score composed for the game and recorded with BBC Symphony Orchestra Discover, and mod support.

Battlesnake AI

A* search for solo play and reinforcement learning for head-to-head matches.

Two team projects in PBL courses at The University of Osaka. Our snakes played against classmates' snakes through the official Battlesnake API.

Solo: proposed and implemented an A* strategy in Python that switches between safety-first and food-first modes — 3rd place in class.
Duel: when our first Monte Carlo approach underperformed, the team moved to reinforcement learning. Building on existing open-source implementations, I trained and evaluated PPO / A2C models with self-play and connected them to the game server — 1st place in class.
