라떼군 이야기

Hi there!

I’m Mr. Latte, a freelance software engineer based in Seoul, South Korea. With over two decades of hands-on experience since 2002, I build web applications, mobile apps, and cloud-based services. Currently, I’m developing and operating my own SaaS products while taking on freelance projects.

What I Do

I specialize in full-stack development across diverse platforms and technologies. From desktop applications to modern cloud-native systems, from monolithic architectures to microservices—I adapt to what each project needs. My work has reached millions of users through products like ALTools and CABAL Online.

Services

I’m currently building:

InverseOne - Algorithm-based contrarian investment analysis platform for Korean, US, and Japanese stocks and cryptocurrencies
Libsac - Comprehensive platform providing daily updates on competitions, events, performances, and lectures
GameSnapshots - Community platform for sharing game screenshots and connecting with fellow gamers
Hizine - Film and drama location discovery platform for planning trips to real-world filming spots
