Summary
I majored in Western cuisine and gained extensive experience working in team-based cooking competitions during college. These experiences taught me the value of planning, timing, and teamwork to achieve high-quality outcomes under pressure. Later, I transitioned into software development to pursue a more scalable and data-driven way to solve real-world problems. Through intensive training and project-based learning, I developed strong skills in backend development, database design, API integration, and data visualization. My background in culinary arts has shaped a detail-oriented and structured approach to development, and I’m excited to continue growing as a developer by building user-focused, reliable systems.
