What I’ve built

I build my own tools and use them every day — never outsourced. That’s exactly why I build yours myself, too.

① Yangpyeong charcoal-grill restaurant · Attendance app

Paper sign-in → one-click reporting app

Problem Checking each employee’s clock-in time by hand in Excel, every single day
Solution Staff clock in themselves → auto-tallied → sent to the accountant and labor advisor in one click
Result The repetitive manual work is gone

Install-free web app (PWA) · BYOC

② Catering company · Content vending machine

One event, content generated automatically

Problem Plenty of events, but no time to write and post promotion
Solution One event auto-generates blog and Instagram content
Result Consistent daily publishing became possible

③ Jeonwon-jipsa · Own service

Payment-integrated website (self-operated)

“Jeonwon-jipsa,” a decluttering & cleaning service I run myself. I planned and built the website firsthand — from the introduction all the way to on-site Toss payment.

I build the tools for my own business

④ Insurance planner · AI analysis app

Policy analysis to recommend the best coverage

Problem It’s hard for a planner to compare every coverage option for each client one by one
Solution An AI tool that analyzes policy terms and finds the most favorable coverage
