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.

I m building Crazy Sajangnim, an early-stage platform that combines discounted fashion discovery with a shared community blog.

The name comes from the Korean phrase , which roughly means The boss has gone crazy. Korean retailers often use it playfully to advertise prices so low that the owner must be crazy. I wanted the name to preserve that part of Korean shopping culture while building something that connects Korean and U.S. fashion retailers.

However, the question I m most interested in testing isn t simply whether people want another place to find discounted products. It s whether a blog can recreate some of the social experience of shopping together.

The idea is to let shoppers post clothing photos, share deals, ask for sizing or styling advice, compare products, and get opinions before purchasing. Rather than evaluating everything alone across multiple tabs, shoppers could bring their discoveries and questions into one shared feed.

Online shopping gives us access to more fashion than ever, but finding a genuinely good deal can still take far too much time. Discounted products are scattered across different retailers, prices appear in different currencies, and shoppers often have to search multiple websites before finding the right item. Even after discovering something interesting, making the final decision can feel surprisingly lonely. There is no friend beside you to ask, Does this look worth it? or How would you style this?

I created Crazy Sajangnim to make that experience easier and more social. It is a fashion-discovery platform that brings discounted designer products from Korean and U.S. retailers into one place. Rather than visiting numerous stores separately, shoppers can explore sale items through a single interface and filter them by market, brand, category, and gender. The platform processes product information including the brand, price, currency, category, image, retailer, and intended market so users can spend less time searching and more time discovering fashion they actually want to wear.

One of Crazy Sajangnim s central features is its Korean and American market support. Fashion shoppers often discover that a brand or product available in Korea may have a different price, selection, or discount in the United States. Crazy Sajangnim helps organize Korean listings in KRW and American listings in USD, allowing users to browse the market that is most relevant to them. This cross-border approach is especially useful for people interested in Korean fashion as well as international designer brands.

The platform is also designed to support an expanding selection of brands. Alongside established labels, Crazy Sajangnim can help shoppers discover smaller, emerging, or regionally popular designers that may be difficult to find on large international shopping platforms. New brands can be added through the administrative system, while aliases and product-inference logic help identify and organize search results by brand, category, gender, price, and currency.
