Software engineer. I build software people use at work.
Client project
NU's women professors were recorded only in scattered documents. I led four developers building a public directory, member portal, and admin system. 187 members migrated, 90 endpoints live.
Production app
A kids' futsal academy ran on WhatsApp and notebooks. I built one app for parents, coaches, and admins, on my own. 211 active students use it.
Personal project
Train seats sell out between manual checks. I wrote a Go service that watches the official booking site and messages me on Telegram. It found a seat and sent the booking link.
Apr 2026–present
IT Digitalization Staff
Main developer of DX-Platform, the plant's replacement for paper and Excel: 1,400 of its 1,800 commits are mine. Since April I shipped line patrol, improvement plans, quality-cost tracking for 2,500+ defect lots, and QC checksheets that used to take three days on paper. Three of the four went live a month early.
Oct 2025–Mar 2026
IT Digitalization Intern
Training requests, approvals, and skill records all ran on paper. I built the training system and the approval engine every later module reuses; both went live on schedule in February. Hired as contract staff when the internship ended.
Jun–Aug 2025
Fullstack Developer Intern
An HRIS used by 30+ hospitals needed to be more stable. I fixed bugs and added input validation, shipping through CI/CD and code review.
Nov 2024–May 2025
Fullstack Developer Intern
Every travel booking had to be re-entered into Accurate ERP by hand. I built middleware on Cloud Run that passes transactions through Pub/Sub. They now sync on their own.
