About
I am a Frontend Engineer with 5+ years of experience in the startup industry.
I am passionate about building user-friendly and engaging web applications.
I enjoy actively participating in projects from the planning stage, contributing ideas, and engaging in intense discussions to produce optimal results that I then implement into code with a sense of immersion and accomplishment.
Building upon this passion, I aspire to become a frontend developer who provides users with convenient and enjoyable experiences, creating various features that have a positive impact throughout the service usage process.
