Jinny Moon's profile on Product Hunt

About

I’m Jinny, a Computer Science student at Boston University and a software engineer passionate about building products that connect technology, creativity, and community. My goal is to create practical, human-centered technology that solves real problems and makes digital experiences feel less isolating. I’m currently building Crazy Sajangnim, a platform that combines designer-fashion sale discovery with a community where shoppers can exchange honest feedback, share styling ideas, and make purchasing decisions together. Long term, I aspire to become a founder and engineer who builds innovative global products that bring people together and turn everyday frustrations into meaningful experiences.

I’m building the place I wish existed between “I found it” and “I bought it.”

Finding clothes online is actually the easy part.

The harder part is everything that happens after:

Is this actually a good price?
Does anyone know how this fits?
Would I still wear this six months from now?
Is there a better version somewhere else?
Should I buy it before it sells out?

Most shopping sites are designed to get you from product page checkout as quickly as possible.

How I went from CS student to building a fashion startup

Hi everyone! I m Jinny

I m a Korean-American Computer Science student at Boston University, currently working as a Software Engineer at EXTORY in Seoul. I spend most of my time building products, working on frontend and admin systems, experimenting with AI-powered developer tools, and learning as much as I can about what makes people actually want to use a product.

Outside of software, one of my biggest interests has always been fashion. I love discovering designer brands, comparing prices between Korea and the U.S., finding pieces on sale, looking at how other people style things, and having those very serious conversations with friends that start with:

Should I buy this?

Hi Product Hunt — I’m Jinny, and I’m Making Online Shopping Less Lonely 👋

Hi everyone! I m Jinny, a Korean American Computer Science student at Boston University and a software engineer.

I m currently building Crazy Sajangnim, an early-stage fashion platform featuring sale items from Korean and U.S. retailers. The name comes from the Korean phrase , or The boss has gone crazy, which is often used to advertise surprisingly large discounts.

The part I m most excited to test is the community blog. Shoppers can share clothing discoveries, upload photos, ask for opinions, exchange styling or sizing advice, and enjoy a co-shopping experience through one shared feed.

The community is still small most posts currently come from my friends and me so I m here to learn from other makers while continuing to build it. If you enjoy fashion, you re welcome to join with a simple Google login, share a post, and shop with us.
