Experience


2023/10 - 2024/08

Head of Accounting/Websites Coding @ Overfocus

- Accounting
 I created a financial system as one of the early members of Overfocus.
- Websites Coding
 I was in charge of HP&LP coding.

I was selected as 1 of 41 students to pursue the Waffle College Tech Career Course where I learned web programming and the software development cycle from scratch in 8 months. I developed Meishi Kakumei / 名刺革命 in a team of 5 in a fast-paced environment with mentorship from industry leaders which were presented to 50+ people. We utilized JavaScript, PHP, CSS, MySQL, HTML, and Figma to develop Meishi Kakumei / 名刺革命 to help you solve the following four problems:
・business cards are discarded when you change departments,
・it is difficult to manage the business cards you receive,
・printing costs are high,
・and most students do not have business cards
while collaborating and peer programming with team members.
