Experience

Responsibilities

• —Found, reproduced and reported defects as part of a five-person debugging team
• —Wrote and ran test cases; organised bug reports and tracked their status
• —Helped raise the quality of multi-platform games shipping on mobile and Steam

Key achievement

Uncovered a hard-to-reproduce, critical bug in a key feature ahead of release. By digging through the log files I pinned down the exact conditions that triggered it and shared them with the development team, so the fix landed before launch.

What I learned

• —Looking at defects from an engineer’s point of view, not just a QA one
• —Communicating repro steps and context accurately and concisely

Overview

Planned and ran a farewell party for graduating members (about 75 people) at the Shibuya live house SHIBUYA DAIA, handling everything from initial planning to on-the-day operations and accounting.

What I did

• —Scheduling, venue booking and budgeting (including setting a ticket price guideline)
• —Promotion and attendee management; running the programme and coordinating the whole event on the day
• —Turned the operations flow into a template and wrote handover docs for the following year

Outcome

The documentation was well received: in March 2026 the next cohort will use it to hold the event at the same venue.

Overview

Built a web app that proofreads press releases with AI in a four-person team at a hackathon hosted by PR TIMES. Three days of intensive development.

My role

• —Backend: implemented the endpoints that call the AI API
• —Set up the team’s Git branching and pull-request based workflow

What I learned

In a short team sprint, agreeing on a minimal set of Git rules and coding conventions directly affects both speed and quality.
