In my first full-time role at Sera Global, I've contributed to production systems for Japan-based clients, working on purchase and reward flows, improving performance for data-heavy interfaces, and collaborating cross-functionally to deliver end-to-end functionality.

Through this work, I've helped improve system performance in user-critical flows—boosting React table rendering performance for large-scale data views and supporting applications handling 2,400+ monthly transactions. These experiences reinforced how frontend responsiveness, backend efficiency, and overall system design together shape real user experience.

I strongly value learning by doing. When facing unfamiliar challenges, I take initiative to understand the problem deeply, apply the right tools, and continuously improve both the product and my engineering skills through real-world implementation and feedback.
