Experience

Jun - Jul 2026
Software Engineer Intern
Gofive Co., Ltd.
Worked on empeo, a B2B HR platform built as an Angular micro-frontend on ASP.NET, and Decio, an internal Scrum tool in Next.js and .NET.
- Closed 74 tickets on empeo in production, working across every layer: the Angular micro-apps, the shared design system, the ASP.NET Core API, and SQL Server stored procedures. Recurring defects got fixed in the design system so every micro-app picked up the fix at once.
- Built features on Decio, including an onboarding flow that matches new logins to employee records through a three-tier fallback, cutting manual placement from 3 steps to 1. I also went through the tool as a real user to find bugs and rough edges, then fixed the ones I found.

Moo-ney: LINE Money Tracker

I often forgot to update my budget spreadsheet. Now I text what I spent, or send a bank slip, to a LINE bot, and it fills in the sheet for me.

Household BP Logger

Grandpa's blood pressure results were not kept in one place. Now the family sends a photo of the monitor in LINE, and a bot adds the numbers to a shared table.
