    Chavo(Chasing hard allows valuable opportunities.) I majored in computer science and anthropology at Seoul National University. I love using participatory observation in my life and learning insights from doing things first. At the suggestion of the gym owner, who asked me to work as a personal trainer, I achieved the National Coaching Certification of bodybuilding in Korea and worked as a personal trainer, released the music I made through a music distribution company and received royalties for the music, and started web development when CEO Lee Seung-yong told me that I needed web development, and now I am in charge of the overall web development of Codetree. Why not? It's the first thought before doing something. Even in product development, I try to make decisions based on quick execution, and I try to use the lessons learned to make the product a little more perfect. For me, I don't hesitate to learn new skills and try new ways of solving problems.

    I'm New here. I'm interested in FrontEnd, BackEnd, and Application. I'm mainly focusing with the front end now. I Look the various codes, and strive to improve the code. I want to grow together through learning and communication. I majored in advertising industry psychology at university, Because I was curious about how human psychology and industrial structure marketing work, and how to predict how human psychology works and what results it produces. I've been curious about those points since I was young, so I think the process of solving problems and producing results is similar to this from the perspective of the developer I'm doing now. In particular, I wonder how the process of solving problems together and the knowledge of the domain will lead me to be more interesting based on communication with team members. So I want to try it. *Speak : Korean / English *WhatsApp : +82 10 8324 0892 *Phone : +82 1083240892 *Email : hsg829@gmail.com *Experience : New comer *Education : Bachelor Degree / Daejeon University(south-korea) *Skills : Typescript / React.js / Next.js / React-Query / Recoil / Zustand / Firebase / RestfulApi / Css / Redux / Tailwind / Style Component / Aws / Docker / Hooks / CI,CD / Github /
